Configuring WDM Services (Manually by Station)
About This Chapter When manually configuring WDM services by station, you need to perform various operations such as configuring board service types and creating cross-connections. Configuring WDM services in this mode involves multiple NMS GUIs and the configuration process is complex. However, the mode is applicable to various scenarios and very flexible. 2.1 Basic Concepts The basic concepts involved in WDM service configuration include electrical cross-connections, WDM service types, and board models. Understanding the basic concepts helps you successfully configure services. 2.2 WDM Service Configuration Flow This section describes the configuration process of boards and services. Before configuring WDM services according to the configuration flow, complete the basic configuration of NEs according to the configuration flow of creating a network. 2.3 Configuring WDM Services for OTU Boards Without Cross-Connect Capability This section describes how to configure the GE services by using the LDM board, which is a type of OTU board that does not require cross-connection configuration. 2.4 Configuring WDM Services for OTU Boards with Cross-Connect Capability This section describes how to configure GE services by using the LQMS board. 2.5 Configuring WDM Services for Tributary Boards and Line Boards This section describes how to configure GE services by using the TQM and NQ2 boards. 2.6 Configuring WDM Services for Boards with the Layer 2 Switching Function This section describes how to configure GE services by using the boards with Layer 2 processing functions (the TBE and L4G boards in this example). 2.7 Configuring 10GE LAN Services by Using the TDX and NS2 Boards This section describes how to configure 10GE LAN services by using the TDX and NS2 boards. 2.8 Parameters Describes the parameters involved in the WDM services configuration.

2 Configuring WDM Services (Manually by Station)
2.1 Basic Concepts The basic concepts involved in WDM service configuration include electrical cross-connections, WDM service types, and board models. Understanding the basic concepts helps you successfully configure services.
2.1.1 Electrical Cross-Connections Cross-connections on WDM equipment can be classified into two types: optical crossconnections and electrical cross-connections. Optical cross-connections cross-connect optical signals and are not related to the types of carried services; electrical cross-connections crossconnect electrical signals and are closely related to the types of carried services. Before configuring WDM services, you need to be familiar with basic types of cross-connections.
Overview of Cross-Connections The grooming function of electrical cross-connections of WDM equipment helps WDM networks to change from static networks to dynamic networks. The MUX/DMUX of the traditional WDM equipment supports only the point-to-point multiplexing scheme, whereas the MUX/DMUX of the NG WDM equipment supports the end-to-end management capability. In addition, the NG WDM equipment supports cross-connections such as GE and ODUk crossconnections. Electrical cross-connections are classified as follows: l l
According to the cross-connection level and granularity, electrical cross-connections are classified into, for example, GE, 10GE, Any, and ODUk cross-connections. According to the cross-connection mode, cross-connections are classified into centralized cross-connections, distributed cross-connections, and mesh-group cross-connections. – Centralized cross-connections: Cross-connections are implemented using crossconnect boards. The board where a cross-connect service is created can be housed in any slot that supports the board. – Distributed cross-connections: Cross-connections are implemented using boards that are housed in paired slots.
l
– Mesh-group cross-connections: Cross-connections are implemented using boards that are housed in mesh-group slots. Electrical cross-connections can be also classified into intra-board cross-connections and inter-board cross-connections according to their positions. – Intra-board cross-connections: Services signals are still on a board after they are processed by a cross-connect unit in the board. As shown in Figure 2-1, crossconnections between channel 1 of client-side port 5 (RX3/TX3) on a board and channel 1 of WDM-side port 201 (LP1/LP1) on the same board are referred to as intra-board cross-connections.

2 Configuring WDM Services (Manually by Station)
When ports or channels at the two ends of cross-connections are corresponded according to the arrangement sequence, the cross-connections are also referred to as direct crossconnections. See Figure 2-2. Figure 2-2 Direct cross-connections A 3(RX1/TX1)-1 5(RX3/TX3)-1

Signal Flow of Electrical Cross-Connections For WDM equipment, the OTU board, tributary board, and line board work together to complete service grooming. Client services are transmitted from the client side of the WDM equipment, and then modulated to the WDM system for transmission after service grooming and convergence. Figure 2-4 considers the OTU board with the GE/Any and ODUk crossconnection function as a module to describe the signal flow of the electrical cross-connections. Figure 2-4 describes the signal flow of the SDH electrical cross-connection service of the OptiX OSN 8800.

Tributary board Line board OTU board (tributary-and-line-joint board) NOTE
The boards that support the grooming of electrical cross-connections have both external ports and internal ports. These ports are classified into the following types: l TX/RX port: client-side optical port of the board that receives and transmits signals. l IP port: internal port that corresponds to the RX/TX port. It can be regarded as a RX/TX port. l AP port: convergence port that represents the internal port of the L2 module. In this case, the corresponding IP port is an external port. l LP: logical port that functions as the connection point of cross-connections. l OP port: internal port that corresponds to the IN/OUT port. It can be regarded as an IN/OUT port. l IN/OUT port: line-side optical port of the board that receives and transmits signals.
The signals are cross-connected in the following process: 1.
The optical signals are transmitted to the OTU board through the RX/TX port and become electrical signals. After the possible L2 processing, the electrical signals are transmitted to the GE/Any cross-connect module through the AP port and work with the possible crossconnect signals from the backplane, to implement the GE/Any cross-connections.
2.
The electrical signals are transmitted to the ODUk cross-connect module through the LP port and work with the possible ODUk signals from the backplane, to implement the ODUk cross-connections. Then, the signals are transmitted to the optical module through an OP port and added to the WDM line for transmission. NOTE
The OptiX OSN 8800 supports the electrical signals that are transmitted to the ODUk cross-connect module through the LP port and work with the possible ODUk signals from the backplane, to implement the ODUk cross-connections. Then, the signals are transmitted to the optical module through an OP port and added to the WDM line for transmission.

NOTE
The boards that support the grooming of electrical cross-connections have both external ports and internal ports. These ports are classified into the following types: l
TX/RX port: client-side optical port of the board that receives and transmits signals.
l
LP: logical port that functions as the connection point of cross-connections.
l
OP port: internal port that corresponds to the IN/OUT port. It can be regarded as an IN/OUT port.
l
IN/OUT port: line-side optical port of the board that receives and transmits signals.
The signals are cross-connected in the following process: Signals are transmitted to an SDH board through the RX/TX port and become electrical signals. Then, the electrical signals are transmitted to the VC4/VC3/VC12 cross-connect module, and work with the cross-connect signals that may come from the backplane to implement VC-4/ VC-3/VC-12 cross-connections. After being transmitted to the SDH processing module on the SDH board, the electrical signals are transmitted to a WDM-side optical module and become the optical signals that have the DWDM standard wavelengths compliant with ITU-T G.694.1.
For details on how to choose ports of a board for cross-connections, see service configuration descriptions of the board in the Hardware Description.
Restrictions on Cross-Connection Configuration l
The slots that support cross-connections vary according to different types of equipment and boards. – The OptiX OSN 8800 supports only centralized cross-connections with the granularity of ODU0, ODU1, ODU2/ODU2e, ODUflex, and ODU3. – The OptiX OSN 6800 supports both centralized cross-connections and distributed crossconnections. When both types of cross-connections are configured, the system uses distributed cross-connections with preference.

– The granularity of centralized cross-connections can be GE, 10GE, ODU1, or ODU2. – The granularity of distributed cross-connections can be GE, ODU1, OTU1, or Any. Cross-connections can be implemented using boards that are housed in seven groups of paired slots: IU1 and IU2, IU3 and IU4, IU5 and IU6, IU7 and IU8, IU11 and IU12, IU13 and IU14, and IU15 and IU16. – The OptiX OSN 3800 supports both distributed cross-connections and mesh-group cross-connections. – The granularity of distributed cross-connections is GE. Cross-connections can be implemented using boards that are housed in two groups of paired slots: IU2 and IU3, and IU4 and IU5. For the OptiX OSN 3800, only the 52TOM board supports distributed cross-connections. – The granularity of mesh-group cross-connections can be GE, ODU1, or Any. Crossconnections can be implemented using boards that are housed in four slots in the mesh group: IU2, IU3, IU4, and IU5. l
If you configure a cross-connection between the two optical ports on the OTU board, the source of a normal cross-connection can also serve as the source of other normal crossconnections, but its sink cannot be the sink of other cross-connections. The two sources of an SNCP cross-connection cannot be the source of other cross-connections, and its sinks cannot be the sink of other cross-connections.
l
When configuring the electrical cross-connection for a service on the OptiX OSN 3800, OptiX OSN 6800, and OptiX OSN 8800, you must make sure that the WDM-side optical channel numbers at the transmit and receive ends of the service in a direction must be the same. Otherwise, the service fails.

2.1.3 Board Model (Standard Mode and Compatible Mode) Starting from V100R006C01, some boards support new board models. To distinguish new models from existing models, the new board models are marked as standard mode and the existing board models are marked as compatible mode. Compared with the compatible mode, the standard mode facilitates operations and reduces maintenance costs. Service configurations on the NMS vary according to board models.
Boards Supporting Standard Mode Table 2-7 lists the boards that support standard mode, the names of the boards in different modes, and the availability of the boards on different types of equipment. Table 2-7 Names displayed on the NMS and availability on different types of equipment

Internal logical ports
Internal logical ports are reserved.
Internal logical ports are removed. Instead, all ODU-level internal logical ports are configured as channels for each physical port and they can be ignored during configuration.
Number of timeslots
The number of timeslots allocated to each service is fixed.
Services can be transmitted if there are sufficient timeslots and timeslot continuity is not required. For example, the maximum permitted bandwidth of a TN53NS2 board is 10 Gbit/s. After the board receives one channel of ODU1 services, it can still receive ODU0, ODUflex, or ODU1 services on the remaining bandwidth.
Comparison of NMS GUIs for Different Modes Service creation operations on the NMS vary according to board models. Table 2-9 uses the TN53NS2 board as an example to illustrate the differences in the board operation GUIs. Table 2-9 GUIs on the NMS

There are connections between the ODU1LP ports of the NQ2 board and WDM-side IN/OUT ports, and therefore cross-connections do not need to be configured.
2.5.3 Configuration Process This section describes how to configure a bidirectional GE service at stations A and B.
Prerequisite Fibers are connected correctly according to the network structure. (Namely, OCh trails can be searched out. For details, see Searching for WDM Trails.) Check parameters of the OTU board and ensure that no error is found. You must be an NM user with "NE operator" authority or higher.
Tools, Equipment, and Materials U2000/Web LCT (U2000 is recommended)
Background Information Due to the limitations of cross-connections over the backplane, the boards configured with interboard cross-connections must be installed in cross-connection slots. For the limitations of crossconnection slots, see the limitations on cross-connections in 2.1.1 Electrical CrossConnections. The available cross-connection capacity of a board depends on the slot where the board is installed. For the OptiX OSN 6800, the available cross-connection capacity of the slots 1, 4, 11, or 14 is 40 Gbit/s; the available cross-connection capacity of any other slots is 20 Gbit/s. For the OptiX OSN 8800, the available cross-connection capacity of all any slots is 40 Gbit/s. Different boards have different cross-connection capacities. For details, see the functions and features of each board in the Hardware Description. If the capacity of the configured services is greater than the available cross-connection capacity, the service configuration fails.
Procedure on the U2000/Web LCT Step 1 Set Service Mode of the client-side ports on the TN12TQM boards at stations A and B to Client Mode. For details, see 12.3 Configuring the Service Mode. Issue 02 (2011-10-31)

CAUTION l When 10GE LAN signals are received on the client side of the TDX board and Port Mapping of the TDX board is set to Transparent Mapping (11.1 G), Line Rate of the 71 (ODU2LP/ODU2LP)-1 port on the backplane side of the TN52NS2 board that services pass through must be set to Speedup Mode. l When 10GE LAN signals are received on the client side of the TDX board and Port Mapping of the TDX board is set to MAC Transparent Mapping (10.7 G), Line Rate of the 71(ODU2LP/ODU2LP)-1 port on the backplane side of the TN52NS2 board that services pass through must be set to Standard Mode. l The Service Mode must be set to ODU2 or Automatic.
2.7.3 Configuration Process This section describes how to configure a bidirectional 10GE LAN service at stations A, B, and C.
Prerequisite You are an NMS user with "Operator Group" authority or higher.
Tools, Equipment, and Materials U2000/Web LCT (U2000 is recommended)
Background Information l
The port mapping mode of 10GE LAN services can be configured as Bit Transparent Mapping (11.1 G) or MAC Transparent Mapping (10.7 G). Users can select a proper mapping mode according to the service transmission requirements.
l
Bit Transparent Mapping (11.1 G) meets customer requirement for transparent bit transport of 10GE LAN signals. In the Bit Transparent Mapping (11.1 G) mode, transmission of signals are achieved by increasing the OTU frame frequency. This ensures the encoding gain and correction capability of FEC. In this mode, however, the bit rate is higher than the standard bit rate of OTU2 signals.
l
MAC Transparent Mapping (10.7 G) is specific to transparent transmission of 10GE MAC frames as required by customers. In this port mapping mode, a 10GE LAN signal is encapsulated in the GFP-F format and then mapped into a standard OTU frame. This mode supports transparent transmission of only client 10GE MAC frames. In this mode, the signals are in standard OTU2 frames. In addition, the FEC/AFEC code pattern is applicable to 10GE LAN services in this mode. Originally, the FEC/AFEC code pattern is intended for 10G SDH services.
l
The port mapping modes of the upstream and downstream board must be the same.

4.1 Overview of the Working Modes This section describes the board working mode and port working mode. A specific service signal flow of a board is available when the board working mode and port working mode are set to specific values.
Board Working mode The TN11TOM and TN52TOM boards support the cascading and non-cascading modes. l
In cascading mode, a maximum of eight multi-rate (< 2.5 Gbit/s) Any services can be input to the TN11TOM or TN52TOM board through the SFP module on the client side. The services are then multiplexed into different timeslots of one or two ODU0 services or one ODU1 service. Each group of ClientLP ports, for example, 201(ClientLP1/ClientLP1)-1 to 201(ClientLP1/ClientLP1)-8 ports, can access a maximum of eight Any services.
l
In non-cascading mode, a maximum of eight multi-rate (< 2.5 Gbit/s) Any services can be input to the TN11TOM or TN52TOM board through the SFP module on the client side. The services are then multiplexed into different timeslots of one to eight ODU0 services or one to four ODU1 services. Each group of ClientLP ports, for example, 201(ClientLP1/ ClientLP1)-1 to 201(ClientLP1/ClientLP1)-4 ports, can access a maximum of four Any services. NOTE
l The navigation path for setting the TN11TOM board is Configuration > WDM Interface > By Board/ Port(Channel) > Board. l The navigation path for setting the TN52TOM board is Configuration > Working Mode. A specific service signal flow of the TN52TOM board is available only when both the board working mode and port working mode are set to specific values.
Port Working Mode The TN52TOM board should be set to the cascading or non-cascading mode. In addition, application scenarios such as the ODU0 or ODU1 mapping mode and tributary-line mode of the ports on the board should be set. As shown in Table 4-1, the TN52TOM board supports 14 working modes. Table 4-1 Mapping between the working modes and signal flows of the TN52TOM board Board Working mode

4.2 Configuration Principles This section describes the principles for configuring the TN52TOM board. The rules for configuring the TN52TOM board are as follows: l
The OptiX OSN 8800 does not support distributed cross-connection.
l
For the OptiX OSN 6800, – The TN52TOM board can groom a maximum of six Any services through the backplane. – The TN52TOM board can groom Any services on the opposite board.

OptiX OSN 8800/6800/3800 Configuration Guide
4 Configuring the TN52TOM Board (Manually by Station)
– The TN52TOM board can groom a maximum of six Any services through the backplane. – The TN52TOM board cannot groom Any services throughout the full-mesh network. – Inter-board ODU1 cross-connections between the TN52TOM and TN52NS2 boards, if required, should be configured in such a manner that the ClientLP3-1 port on the TN52TOM board is cross-connected to the ODU1LP1-3 port on the TN52NS2 board, the ClientLP5-1 port on the TN52TOM board is cross-connected to the ODU1LP1-2 port on the TN52NS2 board. – When a TN52TOM board is used to configure GE service and Any service crossconnections, the TN52TOM board working with another board must be installed in the following slots: – IU2 and IU3 – IU4 and IU5 – When a TN52TOM board is used to configure ODU1 cross-connections, the TN52TOM board working with another board must be installed in the following slots: – IU2 and IU4 – IU2 and IU5 – IU3 and IU4 – IU3 and IU5 l
When the board works in any mode, the source and sink channel IDs for services must be consistent. For example, if a client-side service is configured at ClientLPX.1, the service must be also configured at ClientLPY.1 on the interconnected board. If a client-side service is configured at ClientLPX.2, the service must be also configured at ClientLPY.2 on the interconnected board. That is, service interconnection must be implemented at channels with the same ID (port numbers may be different). This is due to hardware limitations.
l
In non-cascading board working mode, the ports on the board can be set to different port working modes.
l
In tributary-line mode, the ODU1 service does not support centralized cross-connection.
l
When the cross-connect board is the XCS board, the ODU0 scheduling is not supported and thus the following port working mode application scenarios are not supported: – Application Scenario 8: Non-cascading ODU1_ODU0 mode (OTU1->ODU1->ODU0) – Application Scenario 9: Non-cascading ODU1_ANY_ODU0 re-encapsulation mode (OTU1->ODU1->Any->ODU0)
l
When the cross-connect board is the XCM or XCH board, the following port working mode application scenario is not supported: – Application Scenario 10: Non-cascading ODU1_ANY_ODU0_ODU1 reencapsulation mode (OTU1->ODU1->Any->ODU0->ODU1)
4.3 Application Scenario 1: Conversion Between Eight Any Services and Two ODU0 or One ODU1 Electrical Signals This configuration example shows how the TN52TOM board is configured to implement conversion between eight channels of optical signals of any rate from 100 Mbit/s to 2.5 Gbit/s and two ODU0 or one ODU1 (with ODU0 mapping) electrical signals.

4 Configuring the TN52TOM Board (Manually by Station)
Precautions NOTE
When the cross-connect board is the XCM or XCH board, the TN52TOM board cannot groom the ODU1 service in non-cascading ODU0 mode (Any->ODU0[->ODU1]). When the cross-connect board is the XCS board, the TN52TOM board cannot groom the ODU0 service in non-cascading ODU0 mode (Any->ODU0[->ODU1]). NOTE
The total rate of services that are input at each group of ClientLP ports, such as 201(ClientLP1/ClientLP1)-1 to 201(ClientLP1/ClientLP)-4, cannot be higher than 1.25 Gbit/s. Only one GE service can be input at each group of ClientLP ports. The client-side eight pairs of optical ports can access services at a maximum rate of 10 Gbit/s. If a channel of the ClientLP1 port and a channel of the ClientLP2 port are identified by the same number, these two channels cannot be used at the same time. For example, if the 201(ClientLP1/ClientLP1)-1 channel is configured with a service type, you cannot configure a service type for the 202(ClientLP2/ ClientLP2)-1 channel. Service configurations at the ClentLP3 and ClientLP4, ClientLP5 and ClientLP6, and ClientLP7 and ClientLP8 ports must also comply with this restriction.
Procedure on the U2000/Web LCT Step 1 Set Working Mode of the TN52TOM board: Set Board Working mode to Non-Cascading and then set Port Working Mode of all the ClientLP ports to ODU0 mode (Any->ODU0[>ODU1]). For details, see 12.1 Configuring Working Modes. Step 2 Configure the Service Type at the WDM Interface of the TN52TOM according to the service planning. For details, see 12.2 Configuring the Service Type. Step 3 Configure the cross-connections for the eight Any services that are input to the TN52TOM board. 1.
Configure the cross-connections from the RX/TX ports to the ClientLP ports on the TN52TOM board for the Any services that are input to the board. For details, see 12.4.1 Creating Cross-Connections. NOTE
In this configuration, you can set Level to GE or ANY. If you set Level to ANY, you can set Service Type to only FE, FC100, FICON, DVB-ASI, SDI, ESCON, or FDDI. The service type must be the same as Service Type in the WDM Interface window of the TN52TOM board.

Precautions NOTE
The client-side optical ports only can access two OTU1 services, and the OTU1 service can be configured on only the first channel of the ClientLP port. When the Any service is mapped into the ODU0 service, the TN52TOM board supports de-encapsulation and then re-encapsulation of only 10 Any services. NOTE
The client-side optical ports and WDM-side optical ports can be selected as required.
Procedure on the U2000/Web LCT Step 1 Set Working Mode of the TN52TOM board: Set Board Working mode to Non-Cascading and then set Port Working Mode of ClientLP1 and ClientLP3 to ODU1_ANY_ODU0_ODU1 re-encapsulation tributary-line mode (OTU1->ODU1->Any->ODU0->ODU1). NOTE
l The ClientLP5 and ClientLP7 ports do not support the Non-Cascading ODU1_ANY_ODU0_ODU1 reencapsulation tributary-line mode (OTU1->ODU1->Any->ODU0->ODU1) mode l Before the working mode of the ClientLP1 and ClientLP3 are set to ODU1_ANY_ODU0_ODU1 reencapsulation tributary-line mode (OTU1->ODU1->Any->ODU0->ODU1), the working modes of the ClientLP5 and ClientLP7 ports must be set to NONE Mode (Not for Port).
Step 2 Set the type of ports 9 (RX7/TX7) and 10 (RX8/TX8) to Line Side Color Optical Port. For details, see 11.1 Modifying Port. NOTE
When the TN52TOM board is used as a tributary & line board, a corresponding WDM-side optical module must be inserted in the WDM-side optical port, and the Type of this optical port must be changed to Line Side Color Optical Port.
Step 3 Set Service Mode of the client-side port of TN52TOM as OTN Mode. For details, see 12.3 Configuring the Service Mode. NOTE
When the TN52TOM board accesses OTU1 services on the client side, you first need to set the Service Mode of the TN52TOM board to OTN Mode.
Step 4 Set Service Type in the WDM Interface window of the TN52TOM board to OTU1. For details, see 12.2 Configuring the Service Type. Issue 02 (2011-10-31)

4.14 Application Scenario 12: Regeneration of Four OTU1 Optical Signals This configuration example shows how the TN52TOM board is configured to implement electrical regeneration of four OTU1 optical signals. If you set only two of the 7(RX5/TX5), 8 (RX6/TX6), 9(RX7/TX7), and 10(RX8/TX8) optical ports as WDM-side optical ports, the TN52TOM board can implement conversion between six Any services and two channels of OTU1 optical signals. If the 7(RX5/TX5) and 8(RX6/TX6) optical ports are configured as one protection group and the 9(RX7/TX7) and 10(RX8/TX8) optical ports are configured are another protection group, the TN52TOM board can implement conversion between four Any services and two channels of OTU1 optical signals and implement the function of dual feeding and selective receiving at the WDM side.
4.14.1 Configuration Networking Diagram This section describes how to configure the TN52TOM board on a ring network.
Service Requirement See Figure 4-25. The optical NEs (ONEs) A, B, C, and D form a ring network. All the ONEs function as OADM stations. User1 and User2 communicate with each other. Four bidirectional OTU1 services are available between station A and station B. At station A, the TN52TOM board accesses four OTU1 services, decapsulates them into four ODU1 electrical signals, and then converts them into four OTU1 services.

5 Configuring the THA/TOA Board (Manually by Station)
Configuring the THA/TOA Board (Manually by Station)
About This Chapter The THA/TOA board can be configured with different port working modes and is applicable to various scenarios accordingly. You need to manually configure the board by station on the NMS for the application scenarios. The THA and TOA boards are almost the same except for the number of optical ports. The THA board provides 16 optical ports while the TOA board provides 8 optical ports. This chapter uses the TOA board as an example for illustration. The descriptions and configuration of the THA board are similar to those of the TOA board. The THA board differs from the TOA board in the following aspects: l
The first eight client-side ports on the THA board can be configured with cross-connections only to the first eight LP ports; the last eight client-side ports on the THA board can be configured with cross-connections only to the last eight LP ports.
l
The THA board cannot receive SDI and HD-SDI services on the client side.
l
The THA board does not support ODUflex non-convergence mode (Any->ODUflex). Therefore, all configurations related to this port working mode are applicable only to the TOA board.
5.1 Overview of the Working Mode Each port on the TOA board can work in different modes so that services can be processed on different paths. 5.2 Configuration Procedures Six port working modes are available for the TOA board on the NMS. The port for the None (not for ports) mode does not require configurations. The other five modes require configurations. 5.3 Application Scenario 1: ODU0 Non-Convergence Mode When using the ODU0 non-convergence mode, the TOA board performs conversion between eight channels of optical signals with arbitrary bit rates (125 Mbit/s to 1.25 Gbit/s) and eight channels of ODU0 electrical signals. 5.4 Application Scenario 2: ODU1 Non-Convergence Mode Issue 02 (2011-10-31)

Configuring WDM Services (by Station Service Package)
About This Chapter This chapter describes how to configure the TN52TOM, THA/TOA, and LOA boards in station service package mode to achieve one-click configuration. In station service package mode, multiple configurations such as configuring port working modes and service types are performed on a single NMS GUI, facilitating operations and improving configuration efficiency. The station service package mode is applicable only to some fixed scenarios. NOTE
You can also configure the TN52TOM, THA/TOA, and LOA boards in manual station mode. In this mode, you need to perform various operations such as configuring port working modes and service types on multiple NMS GUIs. The configuration process is complex but applicable to various scenarios. For details about the manual station mode, see the related sections for manually configuring the TN52TOM, THA/ TOA, and LOA boards by station.
7.1 Overview of the Service Packages Service packages enable one-click configuration of typical services by issuing multiple configuration commands in batches, facilitating product deployment commissioning and reducing maintenance costs. The configuration commands include commands for configuring working modes, service types, cross-connections, and port types. Configuration contents vary according to boards and service packages. Currently, service packages are available to the TN52TOM, THA/TOA, and LOA boards. 7.2 Configuring Service Packages You can configure service packages for multiple boards in batches or configure the service package for each board separately.

Configuring WDM Services (by Trail)
About This Chapter You can configure WDM services in end-to-end mode by searching for trails and creating trails at different layers. In addition, the NMS provides the signal flow diagram that visually displays the signal flow and the transmission media layer route of trails. This facilitates operations and improves the maintenance efficiency. 8.1 WDM Trail The concept, type, and relevant information about trails are described here. 8.2 Creating OCh Trails by Trail Search After you create fiber connections and configure services for WDM equipment on the U2000, the trail information does not exist in the network layer of the U2000. To manage OCh trails, you need to search for the data of cross-connections and fiber connections over the network to generate end-to-end WDM trails at the network layer of the U2000. 8.3 Configuration Example After you create fibers and configure services for WDM equipment on the U2000, the trail information does not exist in the network layer of the U2000. To manage WDM trails, you need to search for the data of cross-connections and fiber connections over the network to generate end-to-end WDM trails at the network layer of the U2000. 8.4 Parameters: End to End Service Configuration In this user interface, you can configure WDM trails.

ODUk trail: optical channel data unit (ODUk) trail
l
OTUk trail: optical channel transport unit (OTUk) trail
l
OCh trail: optical channel trail
l
OMS trail: optical multiplexing section trail
l
OTS trail: optical transmission section trail
l
OSC trail: optical supervisory channel (OSC) trail
l
The first six types are related to services, and the OSC trail is related to supervisory signals.
l
The OTS trail cannot be deleted from the NMS. You must delete the fiber connection before deleting the OTS trail.
l
The rate level varies with the value of "k" in ODUk/OTUk. For details, see Table 8-1. ODU5G/OTU5G is a level customized by Huawei.

Inverse Multiplexing Trail The rate of the client layer of an inverse multiplexing trail is greater than the rate of the server layer. Hence, an inverse multiplexing client trail needs multiple trails to serve as its server layer. Currently, you can only search for an inverse multiplexing trail, but you cannot create an endto-end inverse multiplexing trail. An inverse multiplexing client trail can take an ODU1 or ODU2 trail as the server trail. That is, an inverse multiplexing client trail cannot take ODU1 and ODU2 trails as the server trails at the same time.
40G inverse multiplexing trail model The transmission rate of a single wavelength is 40G, but a single wavelength cannot be used for long-distance transmission due to an optical layer index (such as dispersion) restriction. In a 40G inverse multiplexing transmission scheme, a 40G signal is converted to four 10G ODU2 signals, each of which uses one wavelength. This is equal to four 10G signals on the line side and lowers the optical layer index requirement. Figure 8-5 shows the inverse multiplexing trail model of the TSXL card. You cannot dynamically adjust the bandwidth of STM-256 or OC768 services whose rate is 40G. Hence, you can search for a client trail only after you configure four ODU2 trails. If you configure only one, two or three ODU2 trails, services are unavailable and you fail to search for the client trail. Figure 8-5 40G Inverse Multiplexing Trail
10G Inverse Multiplexing Trail Model The TDX card is a 10G inverse multiplexing tributary card that has two individual transmission paths. Each path inversely multiplexes a 10G service to multiple ODU1 signals, which are crossconnected to a line card for transmission. The 10G service uses any or all of the four ODU1 signals according to bandwidth status. When the 10G service does not use all of the four ODU1 signals, the 10G service share an ODU2 trail with other ODU1 signals. This saves line resources. Issue 02 (2011-10-31)

8 Configuring WDM Services (by Trail)
Figure 8-6 shows the inverse multiplexing trail model of the IP3 port on the TDX card. A 10G service is an Ethernet service for which you can dynamically adjust bandwidth. The server layer allows one, two, three or four ODU1 trails. Hence, the client trail that you search out is of different rate levels. Figure 8-6 10G inverse multiplexing trail
8.2 Creating OCh Trails by Trail Search After you create fiber connections and configure services for WDM equipment on the U2000, the trail information does not exist in the network layer of the U2000. To manage OCh trails, you need to search for the data of cross-connections and fiber connections over the network to generate end-to-end WDM trails at the network layer of the U2000.
Prerequisite l
You are an NMS user with "Operator Group" authority or higher.
l
Fiber connections must be created correctly for the WDM equipment.
l
If certain cross-connections exist, you can create an optical-layer trail by using any of the following methods:
Precautions
– Delete the original cross-connection and create the optical-layer trail by using the trail function. This method affects services. – Complement cross-connections on NEs and search for the trail. l
Issue 02 (2011-10-31)
You can create only single-NE optical cross-connections from the AM port to the OUT port of the RMU9 board, from the IN port to the DM port of the RDU9 board, from the AM port to the OUT port of the WSMD4/WSMD2 board and from the IN port to the DM port of the WSMD4/WSMD2 board. In this case, the board optical cross-connection is not supported. These single-NE optical cross-connections do not affect services. You need to create such single-NE optical cross-connections and search for trails if you want to manage the services transmitted in the cross-connections by using the trail management function.

Procedure on the U2000 Step 1 In the Main Topology view, choose Service > WDM Trail > Search for WDM Trail from the Main Menu. Step 2 Under Advanced settings, set the search policies. NOTE
In the mode of searching by subnet, the selected subnet range must be independent from the networking aspect. That is, no fiber connection exists between the selected subnet range and the area that is beyond the selected subnet range.
Step 3 Click Next to begin to search for trails. The U2000 takes some time to return the results, depending on the number of services. NOTE
l If there are cross-connections that are collisions and these cross-connections cannot form end to end trails, the U2000 shows the conflicting trails after you perform the search operation. l The principles of verifying a conflict trail are as follows: The networking changes. The trail may cause interruption of service flow. For example, the key information of the trail, including deleting a crossconnection or fiber, is verified.
Step 4 Optional: Click Next to view the conflicting trail information. If you want to set a trail management flag, check the Management Flag check box or right-click it and select the management flag. NOTE
Skip this step if the policy of automatically creating trails after searching is selected in Step 2.
Step 5 Click Next to view all discrete services in the network. NOTE
If Step 4 is executed, the U2000 deletes trails that do not have the management flag from the network layer. This does not affect services of the actual NE or the data of an individual NE on the U2000.
Step 6 After the search is complete, click Finish. ----End
Follow-up Procedure Step 1 In the Main Topology view, choose Service > WDM Trail > Manage WDM Trail from the Main Menu. Step 2 On the Basic Settings tab, select the level of the service being queried for Level. Step 3 Optional: On the Subnet Settings tab, select the subnet being queried. Step 4 Click Filter All. In Manage WDM Trail, check whether the trails on the subnet being queried are consistent with the network design. ----End Issue 02 (2011-10-31)

8.3.3 Configuration Process After searching for the relevant trail information on the U2000, you can create OCh, ODUk, or client trails by specifying the sources and sinks of the trails. This section describes how to configure an end-to-end GE service between NEs A and C.
Prerequisite l
You must be an NM user with "NE administrator" authority or higher.
l
A license for trail management must be available.
l
The OCh server trail must be searched out.
l
The physical and logical fiber connections between and inside all relevant stations must be established correctly.
Tools, Equipment, and Materials U2000
Precautions NOTE
The value of TN52TOM Board Mode is NON-Cascading mode by default. In this case, the 201 (ClientLP1/ ClientLP1) and 205(ClientLP5/ ClientLP5) ports can access a maximum of four services, and the 203 (ClientLP3/ ClientLP3) and 207 (ClientLP7/ ClientLP7) ports can access a maximum of two services. NOTE
A ClientLP port can access only one service that has a rate higher than 1.25 Gbit/s, and this service can be configured in only the first channel of the ClientLP port. The total rate of services accessed by a ClientLP port must be equal to or lower than 2.5 Gbit/s. The client-side eight pairs of optical ports can access services at a maximum rate of 10 Gbit/s. The client-side ports can be grouped as required.
Background Information ODUk SNCP is classified into three types: SNC/I, SNC/N, and SNC/S. The difference among the three types is that they have different monitoring abilities and therefore are triggered by different conditions. l
SNC/I (inherent monitoring): inherent monitoring; the trigger condition is the state of overheads in the SM section. When there is neither need for ODU end to end protection nor need for TCM subnet application, select SNC/I.
l
SNC/S (sub-layer monitoring): sub-layer monitoring; the trigger condition is the state of overheads in the SM and TCM sections. When there is no need for ODU end to end protection but there is need for TCM subnet application, select SNC/S.

Configuring SDH Services
About This Chapter The OptiX OSN 8800 supports SDH boards. Hence, the OptiX OSN 8800 can be interconnected to the SDH equipment. When you configure an SDH service for the OptiX OSN 8800, you can configure the SDH service on a per-NE basis. In this way, you can specify the timeslot and route for the service on each NE. 9.1 SDH Service Configuration Process This topic describes the process of configuring SDH services. The process consists of deploying a network, configuring the source NE, configuring the sink NE, configuring a pass-through NE, and verifying services. 9.2 SDH Service Overhead This topic describes the SDH overheads, including J0, J1, and C2, that the OptiX OSN 8800 supports. 9.3 Configuring Services on the Non-Protection Ring Configure the protection subnet and the services on the non-protection ring separately. It is recommended that you configure the protection subnet before configuring services on the nonprotection ring. 9.4 Configuring 1+1 Linear MSP Services In the case of 1+1 linear MSP, the source NE dual-feeds service signals to the working and protection lines. In normal conditions, the sink NE selectively receives the services from the working line. When the working line is faulty, the sink NE selectively receives the services from the protection line. 9.5 Configuring the Two-Fiber Bidirectional MSP Ring Services To configure the two-fiber bidirectional MSP services, you need to create the MSP subnet protection and MSP services. There is no requirement for the sequence of creating the MSP subnet protection and MSP services. 9.6 Configuring the SNCP Tangent Ring Services With respect to the physical topology, the SNCP tangent ring is similar to the MSP tangent ring. It can protect services on the two SNCP rings when one fiber between any adjacent stations on each ring is cut. For service configuration of the SNCP tangent ring, you should focus on the tangent node. Each bidirectional service that passes by the tangent node must be configured with four pairs of protection groups. Issue 02 (2011-10-31)

9.2.1 Trace Byte Trace bytes are used to trace the connection status between the receive end and transmit end. The trace bytes can be used to detect and solve problems in advance to prevent transmitted services from being affected. This decreases the network restoration time to a great extent.
J0 Byte The J0 byte is located at line 1 and column (6N+1) in a STM-N frame. The J0 byte is the regenerator section trace byte. The J0 byte is continuously to carry an access point identifier of a regenerator section, according to which the receive end verifies the continuous connection to the intended transmit end.
J1 Byte The J1 byte is the first byte in a virtual container (VC) and its location is indicated by the relevant pointer. The J1 byte is the higher order path trace byte. The J1 byte is used to repetitively transmit the access point identifier of a higher order path (HO APId) so that the receive end of the path can verify its continuous connection to the intended transmit end. The J1 byte can be used to detect and solve problems in advance to prevent transmitted services from being affected. This decreases the network restoration time to a great extent.
9.2.2 Signal Label Byte This topic describes the locations and functions of the signal label bytes C2 in SDH overheads.
C2 Byte The C2 byte is the third byte in a VC. C2 is the signal label byte, which is used to indicate the multiplexing structure of VC frames and the payload property. The sent C2 byte must match the received C2 byte. If C2 mismatch occurs, an HP_SLM alarm is generated in the corresponding VC4 path at the local end.
9.3 Configuring Services on the Non-Protection Ring Configure the protection subnet and the services on the non-protection ring separately. It is recommended that you configure the protection subnet before configuring services on the nonprotection ring.
9.3.1 Networking Diagram You can configure a non-protection ring if the services on the ring do not need to be protected. In this case, all the timeslots on the ring can carry services. Figure 9-2 shows a non-protection ring that consists of four NEs. NE1, NE2, NE3 and NE4 are the OptiX OSN 8800. In this example, the source NE NE1 and the sink NE NE3 use the SLO16 boards to add or drop services, and use the SLQ64 boards to transmit SDH services. NE2 and NE4 use the SLQ64 boards to pass through the SDH services. Issue 02 (2011-10-31)

9.3.2 Signal Flow and Timeslot Allocation To configure services on the non-protection ring, you need to plan the traffic direction and timeslot allocation for the services on the non-protection ring. Figure 9-3 shows the signal flow and timeslot allocation. In this example, five STM-1 services are added to or dropped from the source NE NE1 and the sink NE NE3, and the STM-1 services pass through the intermediate NE NE2.

9.3.3 Configuration Process Configuration of the services on the non-protection ring is not related to the configuration of the protection subnet. To configure the services on the non-protection ring, configure the SDH services on the source and sink NEs and the pass-through services on the intermediate NEs if the protection subnet is already created.
Prerequisite The physical topology of the network must be created. The NEs, boards, and fibers must be created on the U2000. The created protection subnet must be consistent with the actual network topology.

9.4 Configuring 1+1 Linear MSP Services In the case of 1+1 linear MSP, the source NE dual-feeds service signals to the working and protection lines. In normal conditions, the sink NE selectively receives the services from the working line. When the working line is faulty, the sink NE selectively receives the services from the protection line.
9.4.1 Networking Diagram This topic describes the configuration of 1+1 linear MSP. The OptiX OSN 8800 is used as only the intermediate NE that transmits an SDH service. The OptiX OSN 3500 adds or drops the SDH service. In Figure 9-4, NE1, NE2, NE5, and NE6 use the OptiX OSN 3500, and the intermediate NEs NE3 and NE4 use the OptiX OSN 8800. In this example, the OptiX OSN 3500 adds or drops the SDH service, and the OptiX OSN 8800 only transmits the SDH service instead of adding or dropping the SDH service. NE1, NE2, NE5, and NE6 use the PQ1 boards as the tributary boards that add or drop the SDH service, and use the SL16 boards as the line boards that transmit the SDH service. The intermediate NEs NE3 and NE4 use the SLO16 boards as the line boards that dual-feed or selectively receive the SDH service, and use the SLQ64 boards as the line boards that transmit the SDH service.

9.5.1 Networking Diagram In the network construction, you should create and name NEs in sequence according to the certain direction, which helps you facilitate the planning of the service flow and service configuration. In the networking diagram shown in Figure 9-6, a two-fiber bidirectional MSP ring that consists of four OptiX OSN 8800 NEs. The OptiX OSN 3500 NEs at the source and sink ends are used to add or drop services. In this example, the source NE NE5 and the sink NE NE6 use the PQ1 boards as the tributary boards that add or drop services, and use the SL16 boards as the line boards that transmit SDH services. NE2 and NE4 on the ring use the SLO16 boards to receive the services sent from the OptiX OSN 3500 or to transmit the services to the OptiX OSN 3500, and use the SLQ64 boards to transmit the SDH services. NE1 and NE3 on the ring uses the SLQ64 board to transparently transmit the SDH services. Figure 9-6 Networking of two-fiber bidirectional MSP ring 12-SLQ64 8-SLQ64 12-SLQ64 8-SLQ64

9.5.2 Signal Flow and Timeslot Allocation If you have created an MSP protection subnet, you can configure a service on a two-fiber bidirectional MSP ring as follows: The source NE adds a service, an NE accesses the service to the ring network, the intermediate NE passes through the service, an NE transmits the service out of the ring network, and then the sink NE drops the service. The service on a ring network has more than one route from the source NE to the sink NE. You need not configure all routes in actual situations. Hence, it is important that you plan and configure the flow of service signals and timeslot allocation properly before you configure a service. Figure 9-7 shows the signal flow and timeslot allocation of a service. In this example, NE5 adds a service, NE2 accesses the service to the ring network, NE1 passes through the service, NE4 transmits the service out of the network, and NE6 drops the service. There are totally five E1 services. Issue 02 (2011-10-31)

9.5.3 Configuration Process The configuration of the two-fiber bidirectional MSP service is independent of creation of its MSP protection subnet. In the case that the protection subnet is created, you need to respectively configure SDH services from the tributary board to the line board on the source NE and the destination NE, and configure the pass-through service on the intermediate NE.
Prerequisite The physical network topology must be created. NEs, boards, and fibers must be successfully created on the U2000. The created protection subnet must be consistent with the actual topology.

9.6 Configuring the SNCP Tangent Ring Services With respect to the physical topology, the SNCP tangent ring is similar to the MSP tangent ring. It can protect services on the two SNCP rings when one fiber between any adjacent stations on each ring is cut. For service configuration of the SNCP tangent ring, you should focus on the tangent node. Each bidirectional service that passes by the tangent node must be configured with four pairs of protection groups. Issue 02 (2011-10-31)

9.6.1 Configuration Networking Diagram The SNCP tangent ring is similar to the MSP tangent ring in terms of physical networking topology. The difference is that you need to configure only one pair of bidirectional services in the tangent point for the MSP ring. For the SNCP ring, however, you need to configure four protection groups for each pair of bidirectional services. In the networking diagram shown in Figure 9-8, two SNCP tangent rings consist of six OptiX OSN 3500 NEs and an OptiX OSN 8800 NE. The OptiX OSN 8800 NE functions as the tangent NE, namely, NE3. The source NE NE1 and the sink NE NE6 use the PQ1 boards as the tributary boards that add or drop services.

9 Configuring SDH Services
9.6.2 Service Signal Flow and Timeslot Allocation The service in the SNCP tangent ring is not transmitted in a fixed direction. The service flow direction depends on the configuration of the working path and the protection path on each NE where the SNCP protection group is configured. When configuring the SNCP protection group on the tangent NE, you need to configure four SNCP protection groups for each bidirectional service in the tangent point. The service timeslot allocation in the SNCP tangent ring is same as the service timeslot allocation on a single SNCP ring. Figure 9-9 shows the service signal flow and timeslot allocation. The service can be transmitted in the MSP tangent ring in different directions and routes. In this example, the service in the ring is transmitted to the ring network from NE1 and then is dropped on the sink NE (NE6). on tangent NE (NE3), four SNCP protection groups need to be configured. The service flow direction is NE1-NE2-NE3-NE5-NE6 or NE1-NE2-NE3-NE7-NE6. There are five E1 services on the ring. Figure 9-9 Signal flow and timeslot allocation NE1: 5xE1

Configuring Ethernet Services
About This Chapter This chapter describes how to configure Ethernet services. The flexible grooming of Ethernet services is implemented by configuring Ethernet services and electrical cross-connections. 10.1 Ethernet Service Types The WDM equipment supports the following Ethernet services: Ethernet private line (EPL), Ethernet virtual private line (EVPL), Ethernet private local area network (EPLAN) services, and Ethernet virtual private local area network (EVPLAN) services. 10.2 Basic Concepts Before you configure Ethernet boards with services, you need to learn the basic concepts of configuring the Ethernet service. 10.3 Configuration Process of Ethernet Services This section describes the configuration process of Ethernet services using figures. 10.4 Configuring Ethernet Services in an OTN System This section describes how to configure Ethernet services in an OTN system. 10.5 Configuring Ethernet Services in an OCS System This section describes how to configure Ethernet services in an OCS system. 10.6 Configuration Example: Configuring EPL Services The EPL service provides a solution for the point-to-point transparent transmission of Ethernet services over an exclusive bandwidth. EPL services are applied to the scenarios where the userside data communication equipment connected to the transmission network does not support VLANs or where the VLAN planning is kept secret from the network carrier. 10.7 Configuration Example: Configuring EVPL (QinQ) Services on a WDM Network EVPL (QinQ) services realize the nesting of VLAN. With the increase of network users, the existing number of VLAN IDs fails to meet the requirement of users. After EVPL (QinQ) services are configured, however, users can be identified through multiple layers of VLAN IDs. In this case, VLAN extension is achieved. 10.8 Configuration Example: Configuring EPLAN Services (IEEE 802.1d Bridge) on a WDM Network The EPLAN service (IEEE 802.1d bridge) provides an LAN solution for multipoint-tomultipoint convergence. This service applies in cases where user-side data communication Issue 02 (2011-10-31)

equipment connected to the transmission network does not support VLANs or where the VLAN planning is kept secret from the network operator. 10.9 Configuration Example: Configuring EVPLAN Services (IEEE 802.1q Bridge) on a WDM Network The EVPLAN service (IEEE 802.1q bridge) provides an LAN solution for multipoint-tomultipoint convergence. This service applies in cases where user-side data communication equipment connected to the transmission network does not support VLANs or where the VLAN planning is open to the network operator. 10.10 Configuration Example: Configuring EVPLAN Services (IEEE 802.1 ad Bridge) on a WDM Network The QinQ technology provides a cheap and easy solution for Layer 2 virtual private networks (VPNs). The IEEE 802.1ad bridge uses the QinQ technology to provide the VPN solution, thus facilitating the identifying, differentiating and grooming EVPLAN services. 10.11 Configuration Example: Configuring EVPL and EVPLAN Services (IEEE 802.1q Bridge) on a WDM Network Based on different VLANs, EVPL and EVPLAN services can be accessed through a same port, which is applicable to the scenario where the EVPL and EVPLAN users share the same port. 10.12 Configuration Example: Configuring EPL Services on a SDH Network EPL services provide the point-to-point Ethernet transparent transmission solution where the bandwidth is occupied exclusively. EPL services are applicable when the communication equipment that is used to access the client-side data in the transmission network does not support VLAN or when the VLAN planning cannot be disclosed to the network operator. 10.13 Configuration Example: Configuring EVPL (QinQ) Services on a SDH Network The EVPL (QinQ) service provides an Ethernet private line solution. The services are applicable where the services of multiple users that have the same VLAN ID are accessed into a transmission network and need to be transmitted on the same VCTRUNK. In the case of EVPL (QinQ) services, a layer of S-VLAN tag is added on the network side to isolate the services of different users from each other. 10.14 Configuration Example: Configuring PORT-Shared EVPL (VLAN) Services on a SDH Network The PORT-shared EVPL (VLAN) service is applicable when the services of multiple users, which are received from the same external port on the Ethernet board at a station, need to be transmitted on different VCTRUNKs to another station or to another external port of the station. 10.15 Configuration Example: Configuring VCTRUNK-Shared EVPL Services on a SDH Network When the services of multiple users that do not carry VLAN tags are accessed into a transmission network and are transmitted on the same VCTRUNK, the VCTRUNK-shared EVPL (VLAN) service is used to isolate the services of different users by adding VLAN tags. In this manner, the bandwidth is shared on the SDH side. 10.16 Configuration Example: Configuring EPLAN Services (IEEE 802.1d Bridge) on a SDH Network The EPLAN service (IEEE 802.1d bridge) provides a LAN solution for multipoint-to-multipoint convergence. This service is applicable where the user-side data communication equipment connected to the transmission network does not support VLAN tags or where the VLAN planning cannot be disclosed to the network operator. 10.17 Configuration Example: Configuring EVPLAN Services (IEEE 802.1q Bridge) on a SDH Network The EVPLAN service (IEEE 802.1q bridge) provides a LAN solution for multipoint-tomultipoint convergence.

equipment, which is connected to the transmission network, does not support VLAN tags or where the VLAN planning cannot be disclosed to the network operator. 10.18 Configuration Example: Configuring EVPLAN Services (IEEE 802.1ad Bridge) on a SDH Network The QinQ technology provides an economical and easy solution for Layer 2 virtual private networks (VPNs).

Based on different VLANs, EVPL and EVPLAN services can be accessed through a same port, which is applicable to the scenario where the EVPL and EVPLAN users share the same port. 10.20 Parameters

10.1 Ethernet Service Types The WDM equipment supports the following Ethernet services: Ethernet private line (EPL), Ethernet virtual private line (EVPL), Ethernet private local area network (EPLAN) services, and Ethernet virtual private local area network (EVPLAN) services. NOTE
When configuring Ethernet services between the client-side ports of the boards, the ALS function of the client side interfaces should be set to Disable.
10.1.1 Ethernet Private Line Service Ethernet private line services include Ethernet private line (EPL) services and Ethernet virtual private line (EVPL) services.
EPL Services Two nodes are used to access EPL services and implement transparent transmission of the Ethernet services to the users. Service of one user occupies one VCTRUNK and does not need to share the bandwidth with the services of the other users, as shown in Figure 10-1. Hence, in the case of EPL services, a bandwidth is exclusively occupied by the service of a user and the services of different users are isolated. In addition, the extra QoS scheme and security scheme are not required. Figure 10-1 EPL services
EVPL Services For EVPL services, services of different users share the bandwidth. Therefore, the VLAN/QinQ scheme needs to be used for differentiating the services of different users. If the services of different users need to be configured with different quality levels, you need to adopt the corresponding QoS scheme. EVPL services are classified into two types, depending on whether the PORT or VCTRUNK is shared. There are two types of EVPL services: l

– QinQ technology-based convergence and distribution of EVPL services PORT-shared EVPL services As shown in Figure 10-2, the services of different users are accessed through an external port (that is, PORT) at a station, and are then isolated from each other by using the VLAN IDs. Services are transmitted to other PORTs at this station through different VCTRUNKs. Figure 10-2 PORT-shared EVPL services
VCTRUNK-shared EVPL services As shown in Figure 10-3, the services of different users are isolated by using the VLAN/QinQ scheme. Hence, the services of different users can be transmitted in the same VCTRUNK. l

l
QinQ technology-based convergence and distribution of EVPL services The implementation principle of the QinQ technology-based EVPL services and the implementation principle of the VLAN tag-based EVPL services are similar. Users of VLAN tag-based EVPL services are identified by only one layer of VLAN IDs. Users of QinQ technology-based EVPL services are identified by multiple layers of VLAN IDs. In this manner, the number of VLANs is extended and more users can be identified.

Based on the Layer 2 switch function, The EPLAN realizes transmission of the accessed data based on destination media access control (MAC) address of the data. The EPLAN services can be accessed from a minimum of two nodes. The services of different users need not share the bandwidth. That is, in the case of EPLAN services, a bandwidth is exclusively occupied by the service of a user and the services of different users are isolated. In addition, the extra QoS scheme and security scheme are not required. There is more than one node in the EPLAN services, Hence, the nodes need to learn the MAC addresses and forward data according to MAC addresses. Therefore, Layer 2 switching is involved.

As shown in Figure 10-4, three branches of user F need to communicate with each other. On NE1, the IEEE 802.1d bridge is established to achieve EPLAN services. IEEE 802.1d bridge can create the MAC address-based forwarding table, which is periodically updated by using the Issue 02 (2011-10-31)

self-learning function of the system. Accessed data can be forwarded or broadcast within the domain of the IEEE 802.1d bridge according to the destination MAC addresses. To avoid broadcast storm, the EPLAN services cannot be set as a ring. If the EPLAN services are set as a ring, the rapid spanning tree protocol (RSTP) or Multiple Spanning Tree Protocol (MSTP) must be started in the network.
EVPLAN Services EVPLAN services of different users need to share the bandwidth. Hence, the VLAN/QinQ scheme needs to be used for differentiating the data of different users. If the services of different users need to be configured with different quality levels, you need to adopt the corresponding QoS scheme. As shown in Figure 10-5, three branches of user G need to communicate with each other. Services of user G need to be isolated from the services of user H. In this case, the operator needs to separately groom the VoIP services and HSI services, be established on NE1 to achieve EVPLAN services. IEEE 802.1q bridge: IEEE 802.1q bridge supports isolation by using one layer of VLAN tags. This bridge checks the contents of the VLAN tags that are in the data frames and performs Layer 2 switching according to the destination MAC addresses and VLAN IDs.

As shown in Figure 10-6, the GE services from user M and the FE services from user N need to access network respectively. In this case, the operator needs to separately groom the GE services and FE services, and isolate the data on the transmission network side. On NE1, the IEEE 802.1ad bridge must be established to support the EVPLAN services. IEEE 802.1ad bridge: The IEEE 802.1ad bridge supports data frames with two layers of VLAN tags. This bridge adopts the outer S-VLAN tags to isolate different VLANs and supports only the mounted ports whose attributes are C-Aware or S-Aware. This bridge supports the following switching modes: Issue 02 (2011-10-31)

10.2 Basic Concepts Before you configure Ethernet boards with services, you need to learn the basic concepts of configuring the Ethernet service.
10.2.1 Tag Attributes In a virtual LAN, the tag attribute of an Ethernet port indicates how the port processes Ethernet packets. Ethernet packets are classified into tagged and untagged packets in 802.1q. A four-byte field is added to the Ethernet frame header of a tagged packet. The 802.1q-compliant field is used to identify the VLAN ID. An untagged packet does not have such a four-byte field. That is, tagged packets contain VLAN IDs and untagged packets do not contain VLAN IDs. An Ethernet port has the following three types, which are Tag aware, Access and Hybrid. See Table 10-1 for details on how an Ethernet board processes tagged and untagged packets at the ingress.

As shown in Table 10-1 and Table 10-2, in an actual network, you need to set the port type for the Ethernet board of an NE according to the Tag attribute of the messages sent from the userside equipment. If the user-side equipment sends the Untag message, set the ingress port to Access and set the egress port to Tag aware. If the user-side equipment sends the Tag message, set the ingress port to Tag aware and set the egress port to Tag aware.
10.2.2 VLAN Group This section describes the application scenarios of the VLAN group.
VLAN Group The U2000 and its managed NG WDM equipment organize certain consecutively accessed VLAN services in a group (usually service demands of the same type) to form a VLAN group. U2000 creates services, manages the QoS flow, and performs Ethernet OAM operations according to the initial VLAN ID so that the other VLAN services in the VLAN group have the same configuration.

10 Configuring Ethernet Services
Application Scenarios of the VLAN Group Currently, the digital subscriber line access multiplexer (DSLAM) does not support the QinQ function. The broadband remote access server (BRAS), however, requires that two layers of VLAN tags should be verified. Based on this, the VLAN grouping function provides the broadband bearer solution from the DSLAM to the BRAS. Currently, the NG WDM equipment supports the following three service scenarios: l
Convergence from multiple GE services to one 10GE service. The BRAS has the 10GE access port. The GE service of the DSLAM is converged to the 10GE port of the BRAS/ PE through the NG WDM VLAN group.
l
Convergence from multiple GE services to one GE service. The BRAS increases the number of access ports. The WDM equipment implements GE transparent transmission or GE convergence from the DSLAM to the BRAS.
l
Private line from GE services to GE services. In the metropolitan enterprise private lines, point-to-point service transparent transmission is required. In this case, a typical transmission channel is adopted. That is, services are transmitted over the 10GE optical line by using the WDM equipment. This is realized as follows: GE services are accessed on the client side of the WDM equipment, and then the GE services are multiplexed to the 10GE line for transmission through the VLAN group.
10.2.3 QinQ The QinQ technology is the basis for implementing EVPL services. QinQ technology achieves VLAN nesting. With the increase of network users, the current number of VLAN IDs fail to meet the network requirement. With the QinQ technology, users can be identified through multiple layers of VLAN IDs. In this case, the VLAN is extended. The VLAN is a LAN technology developed along with the Ethernet switch technology. As the Ethernet technology is deployed largely in the networks of carriers, which are the metropolitan area networks, implementing the 802.1Q VLAN to isolate and identifying users is limited to a great extent. The VLAN tag domain that is defined in the IEEE 802.1Q has 12 bits, which can represent 4K VLANs only. This cannot meet the requirements for identifying a large number of users in metropolitan area networks. In order to increase the number of VLANs, the QinQ technology is developed. The QinQ technology is realized by adding a layer of 802.1Q tags to 802.1Q packets. Thus, the number of VLANs is increased to 4096 x 4096. With the development of the metro Ethernet and the requirement of fine operation, QinQ double tags can be implemented in other scenarios. The inner and outer tags can represent different information. The inner tag (namely the C-VLAN) represents the client and the outer tag (namely the S-VLAN) represents the service. See Table 10-3. Table 10-3 EVPL services based on QinQ Operation

10.2.5 IGMP Snooping The Internet group management protocol (IGMP) Snooping technology is used to enhance the multicast management capability of Layer 2 switching equipment. This technology applies to data service boards that support Layer 2 switching. Based on the interception of Layer 3 IGMP packets, the Layer 2 multicast function is created and maintained, to prevent multicast packets from being broadcast in the Layer 2 equipment.
Overview l
Restriction on the User Access: Illegal users are prevented from using multicast services by configuring the attributes of the multicast strategy, static multicast group, static router port and unknown multicast service forwarding. As shown in Figure 10-9, the multicast group strategy is configured on the equipment. In this way, the range of the group addresses that can be accessed by users through the access control list (ACL) is set. Thus, the multicast packets that can be received by the user host can be controlled.
l
Quick Response to the Link Change: When the topology of the network where the equipment resides changes, the switching equipment should set up new forwarding table items in minutes after receiving the subsequent multicast query packet. As a result, the

multicast services are interrupted for a long time. The IGMP Snooping informs the router of the change in the response spanning tree topology and then quickly transmits the query packets. In this way, the switching equipment in the downstream can learn the multicast information quickly and decrease the service interruption time.
Basic Concepts 1.
Enabling the IGMP Snooping Protocol l If the IGMP Snooping protocol is enabled, the equipment begins to perform the learning and aging of the router port and multicast group. Then, the multicast services are multicast in corresponding multicast groups. l If the IGMP Snooping protocol is disabled, the equipment stops learning and aging of the router port and multicast group, and deletes all the learned dynamic multicast groups.
2.
Router Port The router port refers to the port that faces the multicast router. The Ethernet data board of the equipment regards the port that receives the IGMP query packets as the router port. Router ports are classified into two types: l Dynamic router ports: They receive the IGMP query packets. These ports are decided on the basis of the packets transmitted between routers and hosts. Moreover, they are dynamically maintained. Each of this port can enable a router port aging timer. When the timer times out, this router port is invalid and the multicast group that relies on the router port is deleted. l Static router ports: They are specified with configuration commands, and are not aged. NOTE
Both the L4G and TBE boards do not support the static router ports.
3.
Member Port The multicast member port refers to the port that faces the host of the member. The Layer 2 equipment forwards the multicast service packets to these ports. The multicast group member ports, referred to as member ports for short, are classified into the following two types: l Dynamic member ports, which can receive the IGMP report packets. These ports are decided on the basis of the packets transmitted between routers and hosts. Moreover, they are dynamically maintained. Each dynamic member port is aged after reaching the maximum non-response times. l Static member ports, which are specified by users by using configuration commands, cannot be aged.
Basic Principle As a multicast constraint mechanism of the Layer 2 Ethernet switch, the IGMP Snooping runs at the data link layer, to manage and control multicast groups. When the Layer 2 Ethernet switch receives an IGMP packet between the host and router, the IGMP Snooping analyzes the information carried by the packet. l
When monitoring an IGMP response packet sent by the host, the switch adds the host into the corresponding multicast table.
l
When monitoring an IGMP departure packet sent by the host, the switch deletes the multicast table item corresponding to the host.

By monitoring IGMP packets continuously, the switch creates and maintains the MAC multicast address table at Layer 2, and forwards multicast packets sent by the router according to the MAC multicast address table. If the IGMP Snooping does not run, multicast packets are broadcast at Layer 2. When the IGMP Snooping runs, the packets are multicast instead of broadcast at Layer 2. See Figure 10-8.

Compliant Standard and Protocol: The IGMP complies with RFC 4541, Considerations for Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) Snooping Switches.
Application The IGMP Snooping enhances the resource utilization through multicast forwarding, and the network security by restricting the user access. The advantages of the application of the IGMP Snooping are as follows: l
The network bandwidth can be saved.
l
Signals are forwarded based on the VLAN. Hence, the information security is enhanced.
l
Quick response is made to the link fault. Hence, the reliability is enhanced.
Figure 10-9 shows how to configure the IGMP Snooping function. After reaching the equipment, the multicast packets are distributed from the port of the host where group members exist in the downstream. Issue 02 (2011-10-31)

10.2.6 STP/RSTP/MSTP Generally, the topology for the Layer 2 switching network involves the loop. This may result in the broadcast storm and MAC bridge table flapping. The STP/RSTP protocol is used to trim a bridged LAN to a single spanning tree based on the logical topology. Thus, the broadcast storm can be avoided. MSTP is compatible with the STP and RSTP, and it also fixes the defects of the STP and RSTP. The MSTP fixes the defects of the STP and RSTP. The convergence rate of the MSTP is fast. In addition, traffic of different VLANs passes through corresponding trails, which provides a well load balancing mechanism.
Basic Principle STP applies to a redundant network. Based on a certain algorithm, the STP is used to block redundant trails so that a loop network can be trimmed as a tree network. In this way, the reproduction and endless cycling of packets in the loop network are avoided. Besides, a connected network without redundant trails can be formed in the case of the link failure. RSTP is an improvement of the STP. The RSTP not only supports all the functions of the STP, but also shortens the delay of generating the network topology structure and ensures the connectivity of the network. STP is based on this basic principle. That is, bridge protocol data units (BPDUs) are transmitted between bridges to decide the network topology structure. The STP blocks redundant links to prevent possible loops in the bridged network, and activates the redundant backup links to restore Issue 02 (2011-10-31)

the network connectivity when the working trail fails. BPDUs of STP are classified into two types: l
Configuration BPDU (CBPDU)
l
BPDU for topology change notice (TCN)
RSTP is based on STP. RSTP makes, however, detailed modifications and supplements to STP. Different from STP, RSTP shortens the time delay at the ports from congestion to forwarding, rapidly restores the network connectivity, and provides better services if no temporary loops are caused. The protocol packets transmitted between the bridges using RSTP are rapid spanning tree protocol data units (namely, RST PDUs). NOTE
l OptiX NG WDM the Ethernet data boards support both STP and RSTP. By default, they support RSTP. l Only the LEX4/LEM24 boards support MSTP.
Status Migration for Ports The STP ports are of either the Enabled or Disabled status. The Enabled status is further classified into the following statuses: Blocking, Listening, Learning and Forwarding. According to the forwarding and learning situation of the port, RSTP sorts Disabled, Blocking and Listening to Discarding. For this reason, there are altogether three statuses: Learning, Forwarding and Discarding. Figure 10-10 shows the status migration of an STP port. Figure 10-10 Status migration of STP ports

Issue 02 (2011-10-31)
Disabled: The port in the Disabled status is not involved in the topology and does not forward any packets. Any sub-status of the Enabled status can migrate to this status. The Disabled status must migrate to the Blocking status to enter the Enabled status. The STP cannot control this status because the port in the Disabled status is not involved in the topology. This status can only be controlled by the management. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

l
Blocking: The port in the Blocking status is involved in the topology, and does not forward any packets. Moreover, it does not learn the MAC addresses.
l
Listening: The port in the Listening status is involved in the topology. It can forward BPDUs and discard service packets. It does not, however, learn the MAC addresses. The Listening status is a temporary status when a topology is being created or transformed.
l
Learning: The port in the Learning status is involved in the topology. It can forward BPDUs and discard service packets. Moreover, it learns the MAC addresses of the service packets to make ready for forwarding these packets. The Learning status is a temporary status when a topology is being created or transformed.
l
Forwarding: The port in forwarding status is involved in the topology. It can forward the service packets and BPDUs.
Migrate some ports into the Forwarding or Blocking status by controlling the port status. If a loop exists, at least one port is blocked to release the loop. This is the ultimate goal of the STP algorithm. For the STP, the convergence time is relatively long and the ports play unclear roles. In this case, the RSTP is widely used and is compatible with the STP. In comparison with the STP, the RSTP shows the following improvements. l
By configuration, The definition of the role of a port is clearer and there are following four types of port: Root port, Designated port, Replacing port, Backup port. NOTE
RSTP can configure an edge port to help the topology-independent port to rapidly forward service packets.
l
A more active handshake mechanism is applied to decrease the port status to the following types: Forwarding, Learning, and Discarding.
l
The Discarding status in the RSTP maps with the Listening, Blocking, and Disabled status in the STP.
l
Fast convergence.
Improvement of the MSTP The MSTP fixes the defects of the STP and RSTP. The convergence rate of the MSTP is fast. In addition, traffic of different VLANs passes through corresponding trails, which provides a well load balancing mechanism. The MSTP divides a switching network into different regions, each of which is called an MST region. Within each region, there are multiple spanning trees, which are independent from each other. Each spanning tree is a multiple spanning tree instance (MSTI). The MSTP sets the VLAN mapping table, which specifies the mapping relation between VLAN and MSTI. The network shown in Figure 1 can be considered as an MST region when MSTP is used. Thus, Figure 10-11 shows the result. It is computed that two spanning trees are generated for VLAN 2 and VLAN 3 respectively. l
MSTI 1 takes Switch B as the root switch to forward packets of VLAN 2.
l
MSTI 2 takes Switch F as the root switch to forward packets of VLAN 3.
In this way, all VLAN packets can be properly forwarded. In addition, different VLAN packets are forwarded through different paths. Thus, the load is balanced. Issue 02 (2011-10-31)

10.7 Configuration Example: Configuring EVPL (QinQ) Services on a WDM Network EVPL (QinQ) services realize the nesting of VLAN. With the increase of network users, the existing number of VLAN IDs fails to meet the requirement of users. After EVPL (QinQ) services are configured, however, users can be identified through multiple layers of VLAN IDs. In this case, VLAN extension is achieved.

10.8 Configuration Example: Configuring EPLAN Services (IEEE 802.1d Bridge) on a WDM Network The EPLAN service (IEEE 802.1d bridge) provides an LAN solution for multipoint-tomultipoint convergence. This service applies in cases where user-side data communication equipment connected to the transmission network does not support VLANs or where the VLAN planning is kept secret from the network operator.
10.8.1 Networking Diagram The convergence node needs to exchange Ethernet services with two access nodes at Layer 2. The two access nodes need not communicate with each other.
Service Requirement On the network as shown in Figure 10-21, the service requirements are as follows: l
Three branches (F1, F2, and F3) of user F are located at NE1, NE2, and NE4. F1 needs to communicate with F2 and F3.
l
The Ethernet equipment of user F provides Ethernet optical ports that work in autonegotiation mode and support VLANs. VLAN IDs and the number of VLANs, however, are unknown and may be changed. NOTE
The application scenarios whether one branch needs to communicate with other branches are as follows: l Branches F2 and F3 need to communicate with each other. l Branches F2 and F3 do not need to communicate with each other. If branches F2 and F3 need to communicate with each other, skip Step 2.

10 Configuring Ethernet Services
10.9 Configuration Example: Configuring EVPLAN Services (IEEE 802.1q Bridge) on a WDM Network The EVPLAN service (IEEE 802.1q bridge) provides an LAN solution for multipoint-tomultipoint convergence. This service applies in cases where user-side data communication equipment connected to the transmission network does not support VLANs or where the VLAN planning is open to the network operator.
10.9.1 Networking Diagram The convergence node needs to exchange Ethernet services with two access nodes at Layer 2. LAN services of the two users (H and G) need to be isolated.
Service Requirement On the network as shown in Figure 10-24, the service requirements are as follows: l
Three branches (G1, G2, and G3) of user G are located at NE1, NE2, and NE4 respectively. G2 and G3 do not need to communicate with each other.
l
Three branches (H1, H2, and H3) of user H are located at NE1, NE2, and NE4 respectively.
l
The service of user G needs to be isolated from the service of user H.
l
The Ethernet equipment of user G and user H provides Ethernet electrical ports that work mode in auto-negotiation mode and do not support VLANs.

10 Configuring Ethernet Services
Board Configuration Information In this example, the convergence node NE 1 is configured with one LEM24 board that supports the IEEE 802.1q bridge to implement EVPLAN services in which user data is isolated. The access nodes NE2 and NE4 are configured with an LEM24 board respectively. EVPL services are configured to implement transparent transmission from NE2 and NE4 to NE1.
10.9.2 Service Signals Flow The Ethernet services of the convergence node are received from an external port and tagged with the corresponding VLAN IDs. After the services are forwarded to an internal port through Layer 2 switching, the VLAN IDs are stripped and then the services are transparently transmitted in the WDM network. In this way, the node communicates with a remote node. Figure 10-25 shows the signal flow of the EPLAN services (IEEE 802.1q bridge) and the timeslot allocation to the EPLAN services (IEEE 802.1q bridge).

The IEEE 802.1ad bridge supports the following operation types: l
Adding the S-VLAN tag based on the port
l
Adding the S-VLAN tag based on the port and C-VLAN
l
Performing port mounting based on the port
l
Performing port mounting based on the port and the S-VLAN
This topic describes the four operation types when Bridge Switch Mode of the IEEE 802.1ad bridge is set to IVL/Ingree Filter Enabled. l
Adding the S-VLAN based on the port: The packets that enter the C-Aware port are added with the preset S-VLAN tag, and are forwarded in the bridge according to the S-VLAN filtering table. Before the packets leave the C-Aware port, the S-VLAN tag is stripped.
l
Adding the S-VLAN tag based on the port and C-VLAN: Then entry detection is performed for the packets that enter the C-Aware port. Then, the corresponding S-VLAN tags are added to the packets according to the mapping relationship between the C-VLAN tags and the S-VLAN tags of the packets. If the mapping relationship does not exist, the packets are discarded. After the S-VLAN tags are added, the packets enter the bridge, where the packets are forwarded according to the S-VLAN filtering table. Before the packets leave the CAware port, the S-VLAN tag is stripped. NOTE
l The same C-Aware port supports different C-VLAN tags being mapped to different S-VLAN tags, but does not support the same C-VLAN tag being mapping to multiple S-VLAN tags.
l
Performing port mounting based on the port: The packets that enter the S-Aware port are not filtered. Instead, the S-VLAN switch is performed directly. The packets must have the S-VLAN tags. Otherwise, the packets are discarded. When the packets leave the S-Aware port, the packets are transparently transmitted.
l
Performing port mounting based on the port and the S-VLAN: The entry filtering is performed according to the preset S-VLAN tag. The packets that do not belong to the SVLAN are discarded. Then, the packets are forwarded according to the S-VLAN filtering table. When the packets leave the S-Aware port, the packets are transparently transmitted.
In the case of the four operation types, the following conditions must be met before the packets leave a port: l
The port is contained in the S-VLAN filtering table that is created by the user.
l
The S-VLAN ID corresponding to the port must be specified when the user manually mounts the port to the bridge. – In the case of a C-VLAN port, the S-VLAN ID corresponding to the port is the S-VLAN ID that is added when the packets enter the port. – In the case of an S-VLAN port, the S-VLAN ID corresponding to the port is the SVLAN ID that is set when the user mounts the port to the bridge. If the S-Aware port is mounted based on the port, the S-VLAN ID is considered to contain all the legal SVLAN IDs.

10.14 Configuration Example: Configuring PORT-Shared EVPL (VLAN) Services on a SDH Network The PORT-shared EVPL (VLAN) service is applicable when the services of multiple users, which are received from the same external port on the Ethernet board at a station, need to be transmitted on different VCTRUNKs to another station or to another external port of the station.
10.14.1 Networking Diagram The services of multiple users, which are received from the same external port on an Ethernet board of a station, need to be transmitted to different stations on different VCTRUNKs.
Service Requirement On the network shown in Figure 10-34, the service requirements are as follows: l
The headquarters C1 of user C is located at NE1. Two branches (C2 and C3) of user C are located at NE2 and NE4. The services between C1 and C2 are transmitted in the VLAN of which the VLAN ID is 100. The services between C1 and C3 are transmitted in the VLAN of which the VLAN ID is 200.
l
The services of C2 are isolated from the services of C3. The services of C2 and C3 require a 100 Mbit/s bandwidth respectively.
l
The Ethernet equipment of C1, C2, and C3 provides 1000 Mbit/s Ethernet optical ports that work in 1000M full-duplex mode. The Ethernet equipment of C1 supports VLAN tags, but the Ethernet equipment of C2 and C3 does not support VLAN tags. – The VLAN ID used by the Ethernet services between C1 and C2 is 100. – The VLAN ID used by the Ethernet services between C1 and C3 is 200.

Board Configuration Information In this example, NE1 is configured with an EGSH board. VLAN IDs are used to isolate the data of different users that are received from the same port. NE2 and NE4 are configured with an EGT6 board each. The EPL services are configured to implement service transparent transmission from NE2 and NE4 to NE1. NOTE
The Ethernet boards are classified into the Ethernet transparent transmission boards and Ethernet switching boards, based on the type of the accessed services. The Ethernet transparent transmission boards support only EPL services whereas the Ethernet switching boards support EPL services, EVPL services, and Layer 2 switching. Hence, Ethernet switching boards are used more widely than Ethernet transparent transmission boards.
10.14.2 Signal Flow and Timeslot Allocation The Ethernet services wherein different VLAN IDs are used to isolate the data of different users, are received from the same external port of NE1, encapsulated through an internal port, and then transparently transmitted on the SDH network. In this manner, the node communicates with a remote node. Figure 10-35 shows the signal flow of the PORT-shared EVPL (VLAN) services and the timeslot allocation to the PORT-shared EVPL (VLAN) services. Issue 02 (2011-10-31)

10.15 Configuration Example: Configuring VCTRUNKShared EVPL Services on a SDH Network When the services of multiple users that do not carry VLAN tags are accessed into a transmission network and are transmitted on the same VCTRUNK, the VCTRUNK-shared EVPL (VLAN) service is used to isolate the services of different users by adding VLAN tags. In this manner, the bandwidth is shared on the SDH side.
10.15.1 Networking Diagram The services of multiple Ethernet users are accessed on the same station, transmitted on the same VCTRUNK, and isolated by using different VLAN IDs. In this manner, the bandwidth is shared on the SDH side.
Service Requirement On the network as shown in Figure 10-36, the service requirements are as follows: l
Two branches of user D are located at NE1 and NE2, and need to communicate with each other.
l
Two branches of user E are located at NE1 and NE2, and need to communicate with each other.
l
The services of user D need to be isolated from the services of user E. The traffic of user D and the traffic of user E, however, occupy a 100 Mbit/s bandwidth during different time period.
l
The Ethernet equipment of user D and user E provides 1000 Mbit/s Ethernet optical ports that work in 1000M full-duplex mode and do not support VLAN tags.

Board Configuration Information In this example, NE1 and NE2 are each configured with an EGSH board. Different VLAN IDs are used to isolate the data of different users transmitted on the same VCTRUNK. l
When the data of user D is accessed into the transmission network, the VLAN ID of 100 is added to the data. When the data is transmitted out of the transmission network, the VLAN tag is stripped.
l
When the data of user E is accessed into the transmission network, the VLAN ID of 200 is added to the data. When the data is transmitted out of the transmission network, the VLAN tag is stripped.
10.15.2 Signal Flow and Timeslot Allocation The services of multiple users are received from different external ports on an Ethernet board, tagged with different VLAN IDs, and then transmitted on the same VCTRUNK. In this manner, the services of different users are isolated from each other. After the data arrives at the sink node, the VLAN tags are stripped. Figure 10-37 shows the signal flow of the VCTRUNK-shared EVPL (VLAN) services and the timeslot allocation to the VCTRUNK-shared EVPL (VLAN) services.

10.16 Configuration Example: Configuring EPLAN Services (IEEE 802.1d Bridge) on a SDH Network The EPLAN service (IEEE 802.1d bridge) provides a LAN solution for multipoint-to-multipoint convergence. This service is applicable where the user-side data communication equipment connected to the transmission network does not support VLAN tags or where the VLAN planning cannot be disclosed to the network operator.
10.16.1 Networking Diagram The convergence node needs to exchange Ethernet services with two access nodes at Layer 2. The two access nodes need not communicate with each other.
Service Requirement On the network as shown in Figure 10-38, the service requirements are as follows: l
Three branches (F1, F2, and F3) of user F are located at NE1, NE2, and NE4. F1 needs to communicate with F2 and F3, and requires a 100 Mbit/s bandwidth for communication with each branch.
l
The Ethernet equipment of user F provides 1000 Mbit/s Ethernet optical ports that work in 1000M full-duplex mode and support VLAN tags. The VLAN IDs and the number of VLANs, however, are unknown and may be changed. NOTE
The application scenarios where one branch needs to communicate with other branches are as follows: l Branches F2 and F3 need to communicate with each other. l Branches F2 and F3 need not communicate with each other. If branches F2 and F3 need to communicate with each other, skip Step 1.4.

Board Configuration Information In this example, the convergence node NE1 is configured with an EGSH board that supports the IEEE 802.1d bridge, thus implementing EPLAN services wherein user VLANs are not limited. The access nodes NE2 and NE4 are configured with a EGT2 board each. The EPL services are configured to be transparently transmitted from NE2 and NE4 to NE1.
10.16.2 Signal Flow and Timeslot Allocation The Ethernet services of the convergence node are received from an external port, forwarded to an internal port through Layer 2 switching, encapsulated, and transparently transmitted on the SDH network. In this manner, the node communicates with a remote node. Figure 10-39 shows the signal flow of the EPLAN services (IEEE 802.1d bridge) and the timeslot allocation to the EPLAN services (IEEE 802.1d bridge).

Board Configuration Information In this example, the convergence node NE1 is configured with an EGSH board that supports the IEEE 802.1q bridge, thus implementing EVPLAN services wherein services of different users are isolated from each other. The access nodes NE2 and NE4 are configured with a EGT6 board each. The EPL services are configured to be transparently transmitted from NE2 and NE4 to NE1. NOTE
The Ethernet boards are classified into the Ethernet transparent transmission boards and Ethernet switching boards, based on the type of the accessed services. The Ethernet transparent transmission boards support only EPL services whereas the Ethernet switching boards support EPL services, EVPL services, and Layer 2 switching. Hence, Ethernet switching boards are used more widely than Ethernet transparent transmission boards.

Board Configuration Information In this example, the convergence node NE1 is configured with an EGSH board that supports the IEEE 802.1ad bridge, thus implementing the EVPLAN services in which VoIP data is isolated from HSI data. l
The VoIP services tagged with the C-VLAN ID of 10 from NE2 and NE4 are further tagged with the S-VLAN ID of 100 when they arrive at the IEEE 802.1ad bridge of NE1. Then, the services are forwarded to the VoIP server through Layer 2 switching.
l
The HSI services tagged with the C-VLAN ID of 20 from NE2 and NE4 are further tagged with the S-VLAN ID of 200 when they arrive at the IEEE 802.1ad bridge of NE1. Then, the services are forwarded to the HSI server through Layer 2 switching.
The access nodes NE2 and NE4 are configured with a EGT2 board each. The EPL services are configured to be transparently transmitted from NE2 and NE4 to NE1.
10.18.2 Signal Flow and Timeslot Allocation The services of user M and user N are transmitted from the access nodes NE2 and NE4 respectively to the convergence node NE1 through the Ethernet transparent transmission boards. The VoIP and HSI services carrying different C-VLAN IDs are tagged with different S-VLAN IDs. The service data is isolated and exchanged at Layer 2 through S-VLAN filtering. Issue 02 (2011-10-31)

10.18.3 Configuration Process At the convergence node NE1, you need to create an EVPLAN service (IEEE 802.1ad bridge) and an S-VLAN filtering table. At the access nodes NE2 and NE4, you need to configure transparent transmission EPL services only.
Prerequisite The Creating a Network task must be complete.
Background Information The IEEE 802.1ad provider bridge supports ports with the C-Aware and S-Aware attributes only. The C-Aware ports are used to add and strip the S-VLAN tags. The S-Aware ports are used to transparently transmit the S-VLAN tags. The IEEE 802.1ad provider bridge supports the following operation types: l
Adding the S-VLAN tag based on the port
l
Adding the S-VLAN tag based on the port and C-VLAN
l
Performing port mounting based on the port
l
Performing port mounting based on the port and the S-VLAN
This topic describes the four operation types when Bridge Switch Mode of the IEEE 802.1ad provider bridge is set to IVL/Ingress Filter Enabled. l
Adding the S-VLAN based on the port: The packets that enter the C-Aware port are added with the preset S-VLAN tags, and are forwarded in the bridge according to the S-VLAN filtering table. Before the packets leave the C-Aware port, the S-VLAN tags are stripped.
l
Adding the S-VLAN tag based on the port and C-VLAN: The entry detection is performed for the packets that enter the C-Aware port. Then, the corresponding S-VLAN tags are added to the packets according to the mapping relation between the C-VLAN tags and the S-VLAN tags of the packets. If the mapping relation does not exist, the packets are discarded. After the S-VLAN tags are added, the packets enter the bridge, where the packets are forwarded according to the S-VLAN filtering table. Before the packets leave the CAware port, the S-VLAN tags are stripped.

OptiX OSN 8800/6800/3800 Configuration Guide
10 Configuring Ethernet Services NOTE
l A C-Aware port supports different C-VLAN tags being mapped into different S-VLAN tags, but does not support the same C-VLAN tag being mapping into multiple S-VLAN tags.
l
Performing port mounting based on the port: The packets that enter the S-Aware port are not filtered. Instead, the S-VLAN switch is performed directly. The packets must have the S-VLAN tags. Otherwise, the packets are discarded. When the packets leave the S-Aware port, the packets are transparently transmitted.
l
Performing port mounting based on the port and the S-VLAN: The entry filtering is performed according to the preset S-VLAN tag. The packets that do not belong to the SVLAN are discarded. Then, the packets are forwarded according to the S-VLAN filtering table. When the packets leave the S-Aware port, the packets are transparently transmitted.
In the case of the four operation types, the following conditions must be met before the packets leave a port: l
The port must be contained in the S-VLAN filtering table that is created by the user.
l
The S-VLAN ID corresponding to the port must be specified when the user manually mounts the port to the bridge. – In the case of a C-Aware port, the S-VLAN ID corresponding to the port is the S-VLAN ID that is added when the packets enter the port. – In the case of an S-Aware port, the S-VLAN ID corresponding to the port is the S-VLAN ID that is set when the user mounts the port to the bridge. If the S-Aware port is mounted based on the port, the S-VLAN ID is considered to contain all the legal S-VLAN IDs.
Procedure Step 1 Configure the EVPLAN service of NE1. 1.
Set the attributes of the external ports (PORT1 and PORT2 of the EGSH board) used by the VoIP server and HSI server. l In the NE Explorer, select the EGSH board and then choose Configuration > Ethernet Interface Management > Ethernet Interface from the Function Tree. l Select External Port. l Click the Basic Attributes tab. After setting the parameters, click Apply. Then, the Operation Result dialog box is displayed. Click Close. Parame ter

10.19 Configuration Example: Configuring EVPL and EVPLAN Services (IEEE 802.1q Bridge) on a SDH Network The EGSH board supports the EVPL and EVPLAN services (IEEE 802.1q bridge) on a same port. Based on different VLANs, EVPL and EVPLAN services can be accessed through a same port, which is applicable to the scenario where the EVPL and EVPLAN users share the same port.
10.19.1 Networking Diagram Based on different VLANs, EVPL and EVPLAN services can be accessed through a same port.
Service Requirement On the network as shown Figure 10-44, the service requirements are as follows: l
Three branches (G1, G2, and G3) of user G are located at NE1, NE2, and NE4 respectively. The branches need to form a LAN and share a 100 Mbit/s bandwidth. G2 and G3 need not communicate with each other.
l
Two branches of user H are located at NE1 and NE2, and need to communicate with each other.
l
The services of user G must be isolated from the services of user H.
l
The Ethernet equipment of user G and user H provides 1000 Mbit/s Ethernet optical ports that work in 1000M full-duplex mode and do not support VLAN tags.

Board Configuration Information In this example, the convergence node NE1 is configured with an EGSH board that supports the IEEE 802.1q, the access nodes NE2 and NE4 are configured with a EGT6 board each. When the data of user G is accessed into the transmission network, services of different users are isolated from each other by EGSH board on NE1. The EPL services are configured to be transparently transmitted from NE2 and NE4 to NE1 when the NE2 and NE4 are used as access nodes. When the data of user H is accessed into the transmission network, the VLAN ID of 200 is added to the data. When the data is transmitted out of the transmission network, the VLAN tag is stripped.
10.19.2 Signal Flow and Timeslot Allocation When the data of user E is accessed into the transmission network, the Ethernet services of the convergence node are received from an external port and tagged with the corresponding VLAN IDs. After the services are forwarded to an internal port through Layer 2 switching, the VLAN tags are stripped and then the services are transparently transmitted on the SDH network. In this manner, the node communicates with a remote node. The Ethernet services of user H are received Issue 02 (2011-10-31)

About This Chapter This chapter describes basic operations that may be used when you configure services. For example, configure the service type and WDM-side port attributes of the board. You can see this topic if required. 12.1 Configuring Working Modes Before using some boards, you need to configure the port working modes for the boards. Different port working modes enable a board to process services differently. 12.2 Configuring the Service Type The services can be transmitted normally only when the type of the services at the WDM interface of the board is the same as the actual service type. 12.3 Configuring the Service Mode If services such as OTU1 are input to a board, you need to configure the service mode of the board. 12.4 Configuring Common Cross-Connections This section describes how to configure common electrical cross-connections. 12.5 Configuring Service Timeslots For some boards the transmit and receive timeslots of the client-end services should be configured during service creation. 12.6 Configuring SDH Cross-Connections This topic describes how to configure SDH cross-connections. 12.7 Configuring Path Overhead for SDH Services The path overhead is configured for services, which helps network maintenance personnel to maintain the network. 12.8 Configuring the Board Mode The board supports different functions in different board modes. Set the board mode of the board properly according to the actual requirements. For example, when the ND2 board is used as a regeneration board, set the board mode of the ND2 board to the regeneration mode. 12.9 Creating a VLAN Group Issue 02 (2011-10-31)

The VLAN group can extend the number of supported VLAN flows. You can follow the procedure described in this section to create a VLAN group. 12.10 Configuring the Aging Time for MAC Addresses You can configure the aging time for MAC addresses, to implement the dynamic address aging. The MAC addresses that do not appear again on a transport network during the aging time are regarded as having no route requirements. Then these MAC addresses are deleted from the MAC address table to make space for more MAC addresses. 12.11 Configuring MAC Address Filtering MAC address filtering is a broadband transmission solution intended to alleviate the load of the standby router. 12.12 Configuring Port Mirroring You can configure port mirroring to analyze only packets for mirrored ports. In this way, you can monitor all mirrored ports. This helps you to manage the ports. 12.13 Diagnosing Ethernet Protocol Faults When the Ethernet protocol operates abnormally, the U2000 diagnoses the protocol fault, displays the diagnosis contents, and restores the normal operation of the Ethernet protocol. 12.14 Configuring Non-Intrusive Monitoring Non-intrusive monitoring indicates that the board monitors the overhead, however, does not handle it, thus the service is not affected. The non-intrusive monitoring is performed for the overheads that are transmitted through the intermediate nodes between the nodes where the overhead bytes are added or dropped.

12.9 Creating a VLAN Group The VLAN group can extend the number of supported VLAN flows. You can follow the procedure described in this section to create a VLAN group.
Prerequisite You must be an NM user with "NE operator" authority or higher. Applicable to the TBE board of the OptiX OSN 6800 and OptiX OSN 3800. Applicable to the LEX4 and LEM24 boards of the OptiX OSN 8800 and OptiX OSN 6800. Applicable to the EGSH board of the OptiX OSN 8800.
Tools, Equipment and Materials U2000/Web LCT (U2000 is recommended)
Background Information The configuration principles are as follows: l
The VLAN group is of port attributes. It is valid only at the service input port. Both the PORT and VCTRUNK ports can be set as a VLAN group.
l
The configuration of a VLAN group is based on the C-VLAN.
l
When you create a VLAN group, if a service is configured for a member VLAN (a noninitial VLAN in the VLAN group), the VLAN group cannot be created. The service mentioned includes services that involve VLAN configuration, such as EPL service, flow configuration and ETH OAM configuration.
l
When you create a VLAN group, if a service is configured for the initial VLAN, the VLAN group can be created, but the service may be transiently interrupted.
l
The maximum number of VLAN groups is consistent with the number of board Links.
l
After you create the port VLAN group, if the VLAN ID of the services to be created is within the VLAN group, the services must be created based on the initial VLAN ID. If the VLAN ID is not within the port VLAN group, the services are unrestricted.
CAUTION Creating a VLAN group may affect the services.

A Parameters Description
A.36 Non-Intrusive Monitoring Description The Non-Intrusive Monitoring parameter provides an option for enabling or disabling the nonintrusive monitoring. When the client side of a board receives OTN signals, the board does not need to terminate and then regenerate PM or TCM overheads. In this case, the non-intrusive monitoring function can be enabled to monitor the received OTN signals. The function does not affect service signals.
Impact on the System When the non-intrusive monitoring function is enabled for an optical interface on a board, the board detects the QoS of the service and reports alarms if the QoS is poor. Other modules perform operations according to the detected QoS, such as protection switching. If the non-intrusive monitoring function is disabled, the services at the optical port are transmitted transparently.

NE database
There are three types of database on NE SCC board as following: (1) DRDB: a dynamic database in a dynamic RAM, powered by battery; (2) SDB: a static database in a power-down RAM; (3) FDB0, FDB0: permanently saved databases in a Flash ROM. In efficient operation, the NE configuration data is saved in DRDB and SDB at the same time. Backing up an NE database means backing up the NE configuration data from SDB to FDB0 and FDB1. When an NE is restarted after power-down, the NE database is restored in the following procedures: As the SDB data is lost due to power-down, the main control restores the data first from DRDB. If the data in DRDB is also lost due to the exhaustion of the battery, the data is restored from FDB0 or FDB1.

S S1 byte
In an SDH network, each network element traces step by step to the same clock reference source through a specific clock synchronization path, thus realizing the synchronization of the whole network. If a clock reference source traced by the NE is missing, this NE will trace another clock reference source of a lower level. To implement protection switching of clocks in the whole network, the NE must learn about clock quality information of the clock reference source it traces. Therefore, ITU-T defines S1 byte to transmit network synchronization status information. It uses the lower four bits of the multiplex section overhead S1 byte to indicate 16 types of synchronization quality grades. Auto protection switching of clocks in a synchronous network can be implemented using S1 byte and a proper switching protocol.

sub-network
Sub-network is the logical entity in the transmission network and comprises a group of network management objects. The network that consists of a group of interconnected or correlated NEs, according to different functions. For example, protection subnet, clock subnet and so on. A sub-network can contain NEs and other sub-networks. Generally, a sub-network is used to contain the equipments which are located in adjacent regions and closely related with one another, and it is indicated with a sub-network icon on a topological view. The U2000 supports multilevels of sub-networks. A sub-network planning can better the organization of a network view. On the one hand, the view space can be saved, on the other hand, it helps the network management personnel focus on the equipments under their management.
sub-network number
A number used to differentiate network sections in a sub-network conference. A subnetwork ID consists of the first several digits (one or two) of a user phone number. An oderwire phone number consists of the sub-network ID and the user number.
subnet mask
The technique used by the IP protocol to determine which network segment packets are destined for. The subnet mask is a binary pattern that is stored in the client machine, server or router and is matched with the IP address.
subnetwork connection A function, which allows a working subnetwork connection to be replaced by a protection protection subnetwork connection if the working subnetwork connection fails, or if its performance falls below a required level. Issue 02 (2011-10-31)

subnetwork connection SNCTP provides a VC-4 level channel protection. When the working channel is faulty, tunnel protection the services of the entire VC-4 path can be switched over to the protection channel. support
A part used to support and fix a cabinet on the antistatic floor, it is made of welded steel plates and is used to block the cabinets up, thus facilitating floor paving and cabling. Before the whole set of equipment is grounded, insulation plates must be installed under the supports, and insulating coverings must be added to the expansion bolts to satisfy the insulation requirements.
Suppression state
An attribute set to determine whether an NE monitors the alarm. Under suppression status, NE will not monitor the corresponding alarm conditions and the alarm will not occur even when the alarm conditions are met.
Switching priority
There may be the case that several protected boards need to be switched; thus the tributary board switching priority should be set. If the switching priority of each board is set the same, the tributary board that fails later cannot be switched. The board with higher priority can preempt the switching of that with lower priority.
Synchronization Status A message that carries quality levels of timing signals on a synchronous timing link. Message Nodes on an SDH network and a synchronization network acquire upstream clock information through this message. Then the nodes can perform proper operations on their clocks, such as tracing, switching, or converting to holdoff, and forward the synchronization information to downstream nodes. synchronize NE time
To send the system time of the server of the network management system to NEs so as to synchronize all NEs with the server.
synchronous digital hierarchy
A transmission scheme that follows ITU-T G.707, G.708, and G.709. It defines the transmission features of digital signals such as frame structure, multiplexing mode, transmission rate level, and interface code. SDH is an important part of ISDN and BISDN. It interleaves the bytes of low-speed signals to multiplex the signals to high-speed counterparts, and the line coding of scrambling is only used only for signals. SDH is suitable for the fiber communication system with high speed and a large capacity since it uses synchronous multiplexing and flexible mapping structure.
synchronous equipment timing source
The SETS function provides timing reference to the relevant component parts of multiplexing equipment and represents the SDH network clement clock.
synchronous optical network
A high-speed network that provides a standard interface for communications carriers to connect networks based on fiberoptic cable. SONET is designed to handle multiple data types (voice, video, and so on). It transmits at a base rate of 51.84 Mbps, but multiples of this base rate go as high as 2.488 Gbps (gigabits per second).

TIM
trace identifier mismatch
time division multiplexing
A multiplexing technology. TDM divides the sampling cycle of a channel into time slots (TSn, n=0, 1, 2, 3 and so on), and the sampling value codes of multiple signals engross time slots in a certain order, forming multiple multiplexing digital signals to be transmitted over one channel.
Time Slot
Continuously repeating interval of time or a time period in which two devices are able to interconnect.
Time Synchronization
Also called the moment synchronization, time synchronization means that the synchronization of the absolute time, which requires that the starting time of the signals keeps consistent with the UTC time.
time to live
A technique used in best-effort delivery systems to prevent packets that loop endlessly. The TTL is set by the sender to the maximum time the packet is allowed to be in the network. Each router in the network decrements the TTL field when the packet arrives, and discards any packet if the TTL counter reaches zero.

traffic engineering
A technology that is used to dynamically monitor the traffic of the network and the load of the network elements, to adjust in real time the parameters such as traffic management parameters, route parameters and resource restriction parameters, and to optimize the utilization of network resources. The purpose is to prevent the congestion caused by unbalanced loads.
Transaction Language Transaction Language One is a widely used telecommunications management protocol. 1 TL1 is a vendor-independent and technology-independent man-machine language. TL1 facilities can be provided as part of an OSS for interacting with either underlying management systems or NEs. One popular application is for a management system (or NE) to package its trap/notification data in TL1 format and forward it to an OSS component. ...(from authors.phptr.com/morris/glossary.html) Transaction Language 1 (TL1) is a widely used, "legacy", management protocol in telecommunications. It is a cross-vendor, cross-technology man-machine language, and is widely used to manage optical (SONET) and broadband access infrastructure in North America. It is defined in GR-831 by Bellcore (now Telcordia). (from en.wikipedia.org/wiki/TL1)

tributary unit group
One or more Tributary Units, occupying fixed, defined positions in a higher order VCn payload is termed a Tributary Unit Group (TUG). TUGs are defined in such a way that mixed capacity payloads made up of different size Tributary Units can be constructed to increase flexibility of the transport network
Trivial File Transfer Protocol
A small and simple alternative to FTP for transferring files. TFTP is intended for applications that do not need complex interactions between the client and server. TFTP restricts operations to simple file transfers and does not provide authentication. TFTP is small enough to be contained in ROM to be used for bootstrapping diskless machines.

User Datagram Protocol
B Glossary
A TCP/IP standard protocol that allows an application program on one device to send a datagram to an application program on another. User Datagram Protocol (UDP) uses IP to deliver datagrams. UDP provides application programs with the unreliable connectionless packet delivery service. Thus, UDP messages can be lost, duplicated, delayed, or delivered out of order. UDP is used to try to transmit the data packet, that is, the destination device does not actively confirm whether the correct data packet is received.
