NOTE

The SNMP NBI supports two formats of management information bases (MIBs): U2000 MIB and U2000-T MIB. l Both HW-IMAPV1NORTHBOUND-TRAP-MIB.mib and HW-IMAPV2NORTHBOUND-TRAPMIB.mib refer to the U2000 MIB, which is used to manage transport, access, and datacom devices, or crossdomain devices. V1 and V2 indicate the SMI (Structure of Management Information) versions of the HWIMAPV1NORTHBOUND-TRAP-MIB.mib and HW-IMAPV2NORTHBOUND-TRAP-MIB.mib respectively. The OSS selects a version based on its supported SMI version. SMI versions differ in syntax. For details, see RFC 1155 and RFC 1902. l T2000-NETMANAGEMENT-MIB.mib refers to the U2000-T MIB, which supports upgrades of original transport NMSs and can manage only transport devices.

2 Overview

2.1 Introduction The Simple Network Management Protocol (SNMP) northbound interface (NBI) is one of the NBIs provided by the U2000. The operational support systems (OSSs) can access U2000 by the SNMP NBI to monitor and manage alarms in Huawei equipment networks. The SNMP protocol consists of a set of standards for network management and is the most widely used protocol in TCP/IP networks. TCP is short for Transmission Control Protocol and IP is short for Internet Protocol. Huawei developed the SNMP NBI for the U2000 in compliance with industry standards. With this NBI, OSSs can interconnect with the U2000 quickly and manage alarms on the network. NOTE

OSSs are computer systems used by telecommunications carriers to manage performance, inventories, services, and faults of network equipment efficiently. By function, OSSs can be classified into the service assurance OSS, the service provisioning OSS, and the inventory management OSS. In this document, OSSs cover upper-layer NMSs and third-party NMSs (NMS is short for network management system). Currently, the SNMP NBI supports alarm management only and the OSS is usually a service assurance OSS.

2.2 Network Position The SNMP NBI is deployed between the OSS and the U2000; it establishes transmission channels for alarm information between these two systems. After an alarm is generated on the equipment, the alarm is reported to the U2000 for processing. The U2000 then reports the processed alarm to the OSS through the SNMP NBI in real time. The OSS queries, acknowledges, unacknowledges, or clears alarms on the U2000 through the SNMP NBI. Figure 2-1 shows the position of the SNMP NBI in a network.

iManager U2000 Unified Network Management System SNMP NBI User Guide

2 Overview

synchronizing, clearing, acknowledging, and unacknowledging. Alarm synchronizing is to query active alarms.

U2000 At the U2000 side, the primary functions are: l

Reporting alarms

l

Reporting heartbeat NOTE

To enable this function, set third-party NMS parameters only on the U2000 when deploying the SNMP NBI instead of configuring the OSS. Alarm information will be received at the preset port of the OSS server.

After receiving alarms from the equipment or the U2000, the SNMP NBI reports these alarms to the OSS by means of standard SNMP trap messages. The SNMP NBI periodically reports heartbeat to the OSS. Based on the heartbeat, the OSS determines whether the connection with the SNMP NBI is proper. For details on trap messages, see C.3 U2000 MIB Trap. Function

Description

Subscribi ng alarms

Subscribes alarms by alarm severity and alarm category. You can set the severity and category when deploying the SNMP NBI. Sets the alarm field or variable binding (VB).

Reporting alarms

Reports alarms from NEs or the U2000.

Reporting heartbeat

Reports heartbeat and sets the heartbeat period.

OSS At the OSS side, the primary functions are: l

Synchronizing alarms (querying current alarms)

l

Changing filter criteria in real time

l

Acknowledging/Unacknowledging alarms

l

Clearing alarms NOTE

Ensure that the OSS is connected to the SNMP NBI properly before the query function is enabled.

2 Overview

Function

Description

Synchronizing alarms (querying current alarms)

Queries current alarms (uncleared alarms) on the U2000 in the Set operation. To query current alarms on the U2000, the OSS issues the query begin command (value: 1) in the Set operation. After receiving the command, the SNMP agent queries current alarms from the U2000 and reports the result to the OSS. If there are too many alarms and the query needs to be stopped, the OSS issues the query end command (value: 0) in the Set operation. After receiving the command, the SNMP agent stops querying and does not report the result to the OSS. For details on alarm synchronization, see 6.1.3 Synchronizing Alarms. For details on trap messages, see C.3 U2000 MIB Trap.

Querying alarms by criteria

Reports alarms by alarm severity and category. The filter criteria are specified during alarm subscription. You can change filter criteria in real time when loading the U2000 MIB.

Changing filter criteria in real time

Changes filter criteria using the Set operation when the SNMP NBI is running. The change will take effect without restarting the SNMP NBI.

Acknowledging/ Unacknowledging alarms

Acknowledges or unacknowledges current alarms on the U2000 based on alarm serial numbers (SNs).

Clearing alarms

Clears alarms on the U2000 based on alarm SNs.

2.3.2 U2000-T MIB The U2000-T MIB is used to be compatible with upgrades of transport NMSs. It is used to manage only transport NEs. When the U2000-T MIB is loaded, the SNMP NBI supports automatic alarm reporting and synchronizing. Synchronizing alarms is to query active alarms.

U2000 At the U2000 side, the primary function is automatic alarm reporting. NOTE

To enable this function, set third-party NMS parameters only on the U2000 when deploying the SNMP NBI instead of configuring the OSS. Alarm information will be received at the preset port of the OSS server.

After receiving alarms from the equipment or the U2000, the SNMP NBI reports these alarms to the OSS using standard SNMP traps. For details, see D.3 U2000-T MIB Trap.

Function

Description

Subscribi ng alarms

Subscribes alarms by alarm severity and alarm category. You can set the severity and category when deploying the SNMP NBI.

Reporting alarms

Reports alarms from NEs or the U2000.

OSS At the OSS side, the primary function is querying current alarms on the U2000 (current alarms are uncleared alarms). The OSS uses the Set operation to query these alarms. NOTE

Ensure that the OSS is connected to the SNMP NBI properly before the query function is enabled.

To query current alarms on the U2000, the OSS issues the query begin command (value: 1) in the Set operation. After receiving the command, the SNMP agent queries current alarms from the U2000 and reports the result to the OSS. If there are too many alarms and the query needs to be stopped, the OSS issues the query end command (value: 0) in the Set operation. After receiving the command, the SNMP agent stops querying and does not report the result to the OSS. For details on alarm synchronization, see 6.2.2 Synchronizing Alarms. For details on traps, see D.3 U2000-T MIB Trap. Function

Description

Querying all current alarms

Reports all alarms by default. You can stop alarm synchronization using the Set operation.

Querying alarms by criteria

Reports alarms by alarm severity and category. The filter criteria are specified during alarm subscription.

2.4 Security Mechanism The security mechanism used by the SNMP NBI is also the security mechanism of the SNMP protocol. Any access to the SNMP NBI must be authenticated by the security mechanism of the specific SNMP version (SNMPv1, SNMPv2c, and SNMPv3). Figure 2-2 shows that SNMPv1 and SNMPv2c use the community-based security mechanism, while SNMPv3 uses the user-based security mechanism.

SNMP alarm northbound interface

SNMPv1 and SNMPv2 The security mechanism of SNMPv1 and SNMPv2c is community-based: the NMS authenticates NEs based on the community name list and the agent does not check the validity of the community name. SNMP packets are transferred without encryption. Therefore, authentication security and confidentiality are not well guaranteed. l

Before the Get, Get Next, or Set operation, the NMS must know the read and write community names configured for the agent.

l

For trap and inform packets, the community name is the read community name configured for the agent. NOTE

SNMPv1 does not support the inform mode.

SNMPv3 The security mechanism of SNMPv3 is user-based. In terms of security, SNMPv3 emphasizes data security and access control and therefore offers a higher level of security than SNMPv1 and SNMPv2c. In data security, SNMPv3 provides protection for SNMP packets in the following ways: l

Data integrity check The data cannot be modified in an unauthorized manner. Any changes in the data sequence are limited to the allowed extent.

l

Data origin authentication SNMPv3 authenticates users from whom received packets are sent rather than applications that generate these packets.

l

Data confidentiality check When the NMS or agent receives a packet, it checks when the packet was generated. If the interval between the creation time and the system time exceeds the preset time range, this packet will be discarded. This check prevents packets from being maliciously modified and malicious packets from being received.

In access control, the NMS performs security checks on managed objects (MOs) based on SNMPv3. Issue 05 (2013-05-17)

3 Introduction to the SNMP NBI

3.1 Overview SNMP is one of the widely applied NMS protocols in the TCP/IP network. As a widely applied industry standard for the NMS protocols, the SNMP aims: l

To transmit the management information between two nodes.

l

To help the manager to search and modify the information, and locate faults at any node in the network.

l

To help the manager to diagnose the faults, configure the capacity, and generate reports.

The features of the SNMP are as follows: l

Uses the polling mechanism and provides a basic function set.

l

Fits small, fast and cost effective network.

3.2 Network Management Framework The Simple Network Management Protocol (SNMP) is a set of protocols and standards. It provides channels for the OSS to collect network management data from network equipment and for network equipment to report problems and errors to the OSS. The SNMP network management framework consists of the network management system (NMS), agent, management information base (MIB), and SNMP protocols. Figure 3-1 illustrates relationships between them. NOTE

In SNMPv3, both the NMS and the agent are called an entity.

3 Introduction to the SNMP NBI

Processes that run on NEs. The SNMP agent performs the following operations: – Receive, parse, and authenticate query packets from the NMS. – Search the MIB tree, call other modules for operation, and obtain responses. – Construct response packets and send them to the NMS. – Send traps to the NMS if urgent. l

MIB A collection of equipment that the agent can query or set. The agent queries the MIB for required operations.

l

SNMP An application-layer protocol carried over UDP in the TCP/IP structure. Exchanges management information between the NMS and agents. Figure 3-2 shows the position of SNMP in the TCP/IP family. Figure 3-2 Position of SNMP

SNMP UDP IP Link Layer Physical Layer NOTE

For the SNMP NBI, the agent is running on the U2000 and the NMS refers to the OSS. Currently two MIBs are supported: U2000-T MIB andU2000 MIB. For details, see C U2000 MIB and D U2000-T MIB.

3.3 SNMP Message Structure The SNMP message structure also refers to protocol data units (PDUs) or SNMP packet types. PDUs are used for communication between the NMS and agents. Figure 3-3 shows five PDUs. Figure 3-3 SNMP PDUs

3 Introduction to the SNMP NBI

l

GetRequest: The PDU that the NMS uses to visit the agent and obtains one or several parameter values.

l

GetNextRequest: The PDU that the NMS uses to visit the agent and obtains the next parameter value.

l

SetRequest: The PDU that the NMS uses to visit the agent and sets one or more parameter values.

l

GetResponse: The PDU that the agent uses to return one or more parameter values to the NMS as responses to GetRequest, GetNextRequest, and SetRequest packets.

l

Trap: The PDU that the agent uses to send traps to inform the NMS of important events or state changes that occurred in NEs.

GetRequest, GetNextRequest, and SetRequest packets are sent from the NMS to agents while GetResponse and trap packets are sent from agents to the NMS.

3.4 MIB MIB is a key part of the SNMP network management framework. NOTE

For U2000, the MIB defines managed objects that are used by the function interfaces of the SNMP NBI. These definitions are extremely important for the U2000 in that they determine what operations the OSS can perform and what network management information the OSS can obtain.

The MIB covers all managed objects (MOs) and refers to a group of SNMP-based entities. The MIB structure resembles a tree, so it is also called a MIB tree. Each MO is mapped to a leaf node, also called an object or object identifier (OID). The MIB tree is static in that after the agent is started and the MIB is initialized, the NMS queries or modifies MOs based on the current MIB. The NMS manages the MIB in read and write mode. All MOs in a network are displayed as a leaf node in the MIB tree. An MO is identified by OID, a unique path that originates from the root node to the leaf node. An OID consists of a set of integers greater than or equal to 0 and is used to identify an MO in the MIB tree. The structure of management information (SMI) ensures that an MO is mapped to a unique OID. Once the MIB file is released, OIDs are bound to related MOs and this binding cannot be modified. A MO in the MIB cannot be deleted, but can be set to obsolete indicating that this MO is not no longer used.

Figure 3-4 gives an OID example: In the MIB tree, the MO mgmt is marked { iso(1) org (3) dod(6) internet(1) mgmt(2) } or simply 1.3.6.1.2.

3.5 SNMP Packet Operation Process This topic uses the SNMPv1 as an example to introduce the operation process of SNMP packet. The agent on the managed node receives a request packet from the NMS through UDP port. U2000 use 9812 by default. The agent treats the received packet as follows: 1.

Decoding the packet based on basic encoding rules of ASN.1 and representing it in an internal data structure The agent discards the packet if some errors cause the decoding failure.

2.

Checking the SNMP version number contained in the packet The agent fetches the version number from the packet and compares it with the version that it supports. If they are inconsistent, the agent discards the packet.

3.

Checking the community name contained in the packet The community name is inserted by the NMS. If the community name is not the supported one, the agent discards the packet. A trap packet is returned to the NMS at the same time. SNMPv1 provides weak security measures, which are enhanced in SNMPv3.

3 Introduction to the SNMP NBI

Fetching the PDU from the authenticated ASN.1 object If the operation fails, the agent discards the packet.

5.

Handling the PDU The agent handles the PDU according to its type. It searches the MIB to find the MO matching the variable, and then obtains the value of the variable from the module. After that, the agent generates the response packet, encodes it and returns it to the NMS.

6.

The NMS performs the same operations as the agent, and displays the final result.

3.6 Version Evolution Currently there are three SNMP versions: SNMPv1, SNMPv2c, and SNMPv3, all of which are supported by the SNMP NBI.

SNMPv1 l

Mutual access to management information between the NMS (also called SNMP manager) and SNMP agent.

l

Operations include: – Get – Set – Trap

l

Protocol data units (PDU) are: – GetRequest – GetNextRequest – GetResponse – SetRequest – Trap

l

Community-based security model NOTE

The OSS must get the community information from the U2000 administrator.

SNMPv2c SNMPv2 inherits all functions in SNMPv1 and provides the following new features: l

Mutual access to management information between SNMP managers.

l

Operations include: – GetBulk – Inform – Report

l

The format of traps is modified to the same as that of the Get and Set packets.

l

SNMPv2 provides fractionalized error codes. NOTE

The OSS must get the community information from the U2000 administrator.

4.1 Overview This topic describes the background information and the terms involved in the process of deploying and configuring the northbound interface.

Attention Item l

Northbound interface is an optional component of the U2000. A license is required for using this function.

l

If you do not install the northbound interface component during the installation of the U2000, you need to add it manually.

l

The northbound interface is a System single-instance deployment package. Therefore, only one instance can be deployed.

CAUTION l After the northbound interface component is installed or added, you need to add a corresponding instance and configure parameters. Then, the U2000 can start the NBI-related process. l After initializing the database of the U2000, you need to configure the northbound interface instance again. l After the northbound interface instance is configured, you need to restart all the NMS services. l You can configure only one IP address for one network interface. It is not allowed to set multiple IP addresses for the same network interface. It is suggested that configure multiple network interface for multiple IP address. l If the NAT is used to transform addresses between the Msuite server and clients, deploy the NBI on the Msuite client that installed on the U2000 server. Otherwise, the NBI may be failure to deploy. l The U2000 server and the OSS must can communicate with each other. Otherwise, the OSS cannot interconnect with the NBI of the U2000. Therefore, if the U2000 server is configured with multiple network interface cards (NICs) and the NICs are in different network segments, set the IP address for connecting to the OSS as the IP address of the U2000 server. l You must configure the northbound interface again after the IP of NMS changed.

Terms The following explains certain confusable terms: l

Component: It is the software functional unit that you can choose to install. Each component can include multiple deployment packages.

l

Deployment package: It is the software unit deployed on a computer. In distributed mode, the deployment packages of one component may be deployed on different computers. According to the quantity of the instances supported, you can classify the deployment packages into the following types:

4.6 Starting the Msuite The Msuite is a graphical system maintenance tool that is developed for the U2000. The Msuite is used to deploy the instances and distributed system of the U2000. For details of Msuite, refer to appendix "Msuite" in the iManager U2000 Administrator Guide.

4.6.1 Starting the Process of the MSuite Server This topic describes how to start the process of the MSuite server.

Context Generally, the process of the MSuite server server is started with the OS startup. If the process is not started, perform the following operations to start it. NOTE

If the server is a Netra 240, V240, or V440 workstation, the process of the MSuite server is not started with the OS startup.

Procedure l

In Windows OS, check whether the msdaemon.exe and msserver.exe processes are started in the Task Manager window. If you can find the two processes in the process list, the MSuite server is running. If the two processes do not exist in the process list, the MSuite server is not running. In this case, perform the following operations to start the MSuite server: Go to the C:\HWENGR\engineering path, and double-click the startserver.bat file.

l

In Solaris or SUSE Linux OS, run the following command as user root to verify that the MSuite server is running: # ps -ef | grep java

The MSuite server is running if /opt/HWNMSJRE/jre_sol/bin/java -server or /opt/ HWNMSJRE/jre_linux/bin/java -server is displayed. Run the following commands to start the MSuite server if it is not running: # cd /opt/HWENGR/engineering # ./startserver.sh

----End

4.6.2 Logging In to the MSuite Client This topic describes how to log in to the MSuite client.

Context If you consecutively enters incorrect passwords three times, the IP address of the PC on which the MSuite client is installed will be locked by the U2000. The U2000 will unlock this IP address 5 minutes later.

Procedure Step 1 On a computer where the MSuite client is installed, double-click the U2000 NMS Maintenance Suite shortcut icon on the desktop and then wait about one minute. The Login dialog box is displayed. NOTE

l In Solaris/SUSE Linux OS, log in to the Java desktop system as user nmsuser. Otherwise, the U2000 NMS Maintenance Suite shortcut icon is not displayed on the desktop. To start the MSuite client by running commands, run the following commands as user nmsuser. If you have logged in as the root user, you cannot run the su - nmsuser command to switch to the nmsuser user to run the following command: $ cd /opt/U2000/engineering $ ./startclient.sh

l If a dialog box showing The client and server versions are different. Upgrade the client using the CAU. is displayed, the method of upgrading the U2000 client by using the CAU is as follow: 1. Install the U2000 client software in network mode: Enter https://server_IP_address:10443/cau (more secure) or http://server_IP_address:8080/cau in the address box of the Internet Explorer, and press Enter to access the Web installation page. For details, see Installing the U2000 Client in Network Mode in the U2000 Client Software Installation Guide. 2. If you upgrade the U2000 client software using the CAU, the MSuite client is also upgraded. For details, see Upgrading a Standalone U2000 Client in In-Service CAU Mode in the U2000 Client Upgrade Guide.

Step 2 Set the login parameters. The login parameters are described as follows: l IP Address: – To log in to the local MSuite server, use the default IP address 127.0.0.1. – To log in to the remote MSuite server, enter the IP address of the computer where the MSuite server is installed. If multiple IP addresses are configured for the computer, use the NMS application IP address. TIP

The Login dialog box of the MSuite client has the function to keep the login list. Selecting an IP address from the IP Address drop-down list is recommended. If the desired IP address is not displayed in the drop-down list, enter an IP address.

l Port No.: The default port ID is 12212. There is no need to change the default value during login but ensure that the port is not occupied. l User Name: The default user name is admin. l Password: The default password is Changeme_123. If the password has been changed, enter the new password. Step 3 Click Login.

NOTE

The Receive Trap Address is not the IP address of the U2000 server. Currently a maximum of 10 third-party NMSs are supported. The same SNMPv3 user configured for different third-party NMSs, for example, NMS 1 and NMS 2, must use the same authentication and encryption passwords When the U2000-T MIB is used, the SNMP NBI identifies OSSs by read or write community. l If multiple OSSs use the same read or write community, only the first OSS gets the synchronized results when any of the OSSs tries to synchronize data. l It is recommended that each OSS uses a unique read or write community so that the OSS can get correct synchronized results.

CAUTION In a Linux-based HA system, if the floating IP address function is enabled during NMS installation, set Send Trap address and Receive Request from NMS address to floating IP addresses. 2.

Set SNMP security parameters. For security concern, input parameters are encrypted. For example, to set Read Community, click in the Set Password dialog box.

next to Read Community and set parameters

The following are the default security parameters. Modifying these parameters is recommended for security concern. l If the SNMP version is set to v1 or v2c, configure the read and write communities. By default, the read community is Changeme_123 and the write community is Changeme_123. l If the SNMP version is set to v3, configure the V3 User Name, V3 Authentication Password, and V3 Privacy Password for SNMPv3 users. l By default, the user name is admin and the two passwords are blank.

CAUTION In the case of SNMPv3, the V3 User Name is required. If no user name is entered, the SNMP service process cannot start after deployment. To ensure the security of the U2000, passwords must be complex enough. For example, a password must contain eight or more characters of two types. The allowed characters are digits, letters, and special characters. Remember to change passwords regularly. The password must meet the following requirements to safeguard your user account. l Consists more than 8 characters. l The password cannot be the user name or its reverse spelling. l The password must consist of three of the following types of characters at least: l Lower-case letters l Upper-case letters l Digits l Special characters including ~ ! @ # $ % ^ & * ( ) - _ = + \ |[ { } ] ; : ' " , < . > / ? and space 3.

Set the alarm filter criteria, including Alarm Level and Alarm Category. NOTE

Alarms are reported to the OSS based on the defined alarm severity and category. The OSS can change the filter criteria in real time. For details, see 6.1.2 Changing Filter Criteria. Fault: Indicates that the SNMP NBI will report alarm generation and alarm clearance. That is, the second and third places of the value of AlarmCategoryFilter in binary mode are set to 0 when the thirdNMSFaultFilter subinterface is invoked. Event alarm reporting is disabled by default and cannot be configured by using the Msuite. But you can enable this function by following methods. l You can enable event alarm function manually. For details, see 7.3.10 How to report the event alarm. l To configure event alarm reporting, you can invoke the thirdNMSFaultFilter subinterface and set the first place of the value of AlarmCategoryFilter in binary mode to 0.

Configuring the SNMP NBI on the OSS

About This Chapter After the SNMP NBI was deployed properly, the OSS can receive real-time alarms. To connect to the U2000 and enable operations on reported alarms (such as synchronize, acknowledge, unacknowledge, and clear alarms), you need also load the appropriate MIB file to the OSS and set relevant parameters. A maximum of ten OSSs can be connected concurrently to the U2000. For the NMS connection, SNMPv1, SNMPv2c, and SNMPv3 can be used. 5.1 Configuring the SNMPv1 or SNMPv2c NBI The OSS connects to the U2000 through SNMPv1 and SNMPv2c NBIs by using communities for access authentication. Configurations are similar for SNMPv1 and SNMPv2c NBIs. Parameters include the request receive IP address/port on the U2000, SNMP version, and read/ write communities. 5.2 Configuring the SNMPv3 NBI Compared to SNMPv1 and SNMPv2c, the SNMPv3 NBI is characterized by higher security due to its user-based security mechanism. In this mechanism, user names and passwords are used for access authentication and packet data is encrypted. Parameters include the request receive IP address/port on the U2000, SNMP version, security level, authentication/encryption protocol, and authentication/encryption password.

6 Calling the SNMP NBI

Calling the SNMP NBI

About This Chapter The OSS calls SNMP subinterfaces to perform operations such as alarm synchronization on the U2000. Available interfaces vary with the loaded MIB (U2000-T MIB or U2000 MIB). NOTE

Ensure that the OSS has connected to the U2000 through the SNMP NBI and the desired operations have been licensed for use.

6.1 U2000 MIB Subinterfaces When the OSS is loaded with the U2000 MIB, the SNMP NBI provides subinterfaces to enable the following functions: reporting alarms automatically, and synchronizing, clearing, confirming, acknowledging, unacknowledging, and filtering alarms. 6.2 U2000-T MIB Subinterfaces When the OSS is loaded with the U2000-T MIB, the SNMP NBI provides subinterfaces to enable the following functions: reporting alarms automatically and synchronizing alarms.

6.1 U2000 MIB Subinterfaces When the OSS is loaded with the U2000 MIB, the SNMP NBI provides subinterfaces to enable the following functions: reporting alarms automatically, and synchronizing, clearing, confirming, acknowledging, unacknowledging, and filtering alarms.

CAUTION Ensure that the U2000 MIB has been loaded to the OSS. To load the U2000 MIB, set the MIB type to U2000 MIB when deploying the SNMP NBI.

6.1.1 Reporting Real-Time Alarms You do not need to set any parameters for the OSS to receive alarm packets from the U2000 through the SNMP NBI. After the SNMP NBI is properly deployed on the U2000, alarms will be reported to the OSS in real time.

Context The SNMP NBI component has been installed and the SNMP NBI instance has been configured on the U2000. After the trap-receiving IP address or port and SNMP version have been set for the OSS on the U2000, the OSS can receive real-time alarms. You do not need to set related parameters on the OSS. Ensure that the OSS is properly connected to the U2000 and the related ports are permitted by the firewall. For details on how to deploy and configure the SNMP NBI, see 4 Deploying and Configuring SNMP.

6.1.2 Changing Filter Criteria The SNMP NBI allows the OSS dynamically to change filter criteria during its running so only required alarms are reported.

Function The OSS can call the alarm filter interface to change alarm filter criteria dynamically when the SNMP NBI is working.

MIB Definition The OID is 1.3.6.1.4.1.2011.2.15.1.3.5. The full path is iso(1).org(3).dod(6).internet(1).private(4).enterprises (1).huawei(2011).products(2).hwNetManagement(15).hwNmAgent (1).hwNmFault(3).thirdNMSFaultFilter(5) Issue 05 (2013-05-17)

6.1.3 Synchronizing Alarms The SNMP NBI allows the OSS to initiate the synchronization operation to ensure that the alarm information on the OSS and the U2000 is consistent.

Function The UDP-based SNMP protocol cannot guarantee that all alarms are reported to the OSS and some alarm packets may be lost. Therefore, the OSS synchronizes alarms to ensure alarm data consistency and can also stop synchronization. After the synchronization starts, the U2000 sends traps through the SNMP NBI to inform the OSS that the alarm synchronization is started. When the synchronization is complete or stopped, the U2000 will send traps through the SNMP NBI to inform the OSS that the alarm synchronization is ended. Figure 6-1 shows the alarm synchronization process.

Description

Synchronize alarms

1. The OSS synchronizes alarms. 2. The U2000 sends traps through the SNMP NBI to inform the OSS of the start of alarm synchronization. 3. The U2000 sends traps through the SNMP NBI to report the required alarms saved in the database. 4. After the alarms are reported, the U2000 sends traps through the SNMP NBI to inform the OSS of the end of alarm synchronization.

Stop the alarm synchronization

1. The OSS stops the alarm synchronization. 2. The U2000 sends traps through the SNMP NBI to inform the OSS of the stop of alarm synchronization.

NOTE

For details of the alarm synchronization start trap, see C.3.2 Active Alarm Synchronization Start Trap. For details of the alarm synchronization result trap, see C.3.3 Active Alarm Report Trap. For details of the alarm synchronization stop trap, see C.3.4 Active Alarm Synchronization End Trap.

MIB Definition There are two MIB nodes for alarm synchronization: hwNmNorthboundEventSynchronizationCommandStart and hwNmNorthboundEventSynchronizationCommandStop. The former indicates start alarm synchronization, while the latter indicates stop alarm synchronization. The OIDs are 1.3.6.1.4.1.2011.2.15.1.7.7.4 and 1.3.6.1.4.1.2011.2.15.1.7.7.5.

6.2 U2000-T MIB Subinterfaces When the OSS is loaded with the U2000-T MIB, the SNMP NBI provides subinterfaces to enable the following functions: reporting alarms automatically and synchronizing alarms.

CAUTION Ensure that the U2000-T MIB has been loaded to the OSS. To load the U2000-T MIB, set the MIB type to U2000-T MIB when deploying the SNMP NBI.

6.2.1 Reporting Real-Time Alarms You do not need to set any parameters for the OSS to receive alarm packets from the U2000 through the SNMP NBI. After the SNMP NBI is properly deployed on the U2000, alarms will be reported to the OSS in real time.

Context The SNMP NBI component has been installed and the SNMP NBI instance has been configured on the U2000. After the trap-receiving IP address or port and SNMP version have been set for the OSS on the U2000, the OSS can receive alarms in real time. You do not need to set related parameters on the OSS. Ensure that the OSS is properly connected to the U2000 and the related ports are permitted by the firewall. For details on how to deploy and configure the SNMP NBI, see 4 Deploying and Configuring SNMP.

CAUTION The reported alarm field for the U2000-T MIB consists of 36 bound variables (VBs). For details, see D.2 Reported Alarm Field by U2000-T MIB.

6.2.2 Synchronizing Alarms The SNMP NBI allows the OSS to initiate the synchronization operation to ensure that alarms on the OSS and the U2000 are consistent.

Function The UDP-based SNMP protocol cannot guarantee that all alarms are reported to the OSS and some alarm packets may be lost. Therefore, the OSS synchronizes alarms to ensure alarm data consistency and can also stop the synchronization. After the synchronization starts, the U2000 sends traps through the SNMP NBI to inform the OSS that the alarm synchronization is started. Issue 05 (2013-05-17)

7 Maintaining the SNMP NBI

7.1 Maintenance Description This section describes the basic requirement of maintenance SNMP NBI. To ensure that the SNMP NBI works well, there are some requirements as follows: 1.

The maintenance personnel must be familiar with: l Windows or the Sun workstation - Solaris 8 or Solaris 10, and Linux l The SNMP protocol l Basic concepts of the Telecommunication Management Network (TMN)

2.

The U2000 Server runs normally.

3.

The License support SNMP NBI function.

4.

The parameter is correct when you deploy the SNMP NBI by Msuite.

7.2 Deleting and Disabling an SNMP Interface This topic describes how to disable or delete an SNMP interface when the U2000 temporarily need not provide this interface to an external network.

7.2.1 Logging In to the System Monitor Client The U2000 System Monitor Client uses the client/server model. To perform an operation, you need to log in to the server through the U2000 client.

Prerequisites Before login, ensure that the U2000 client and server are connected properly and that the server works correctly.

Context l

The default port number of the server is 31030. Do not change it in normal conditions. Otherwise, you cannot log in to the U2000 server.

l

The login modes include the SSL mode and common mode. In SSL mode, the data is encrypted when being transmitted between the client and the server. In common mode, the data is not encrypted during transmission. To ensure the security of data transmission, you are recommended to use the Security (SSL) mode.

l

The port used for login in common mode is different from that in SSL mode. The port number is 31030 in common mode, and 31080 in security (SSL) mode.

l

After last login, if you do not log in again during the preset period, your account hibernates or the U2000 deletes the account.

l

If you never use a new user account for login, the U2000 does not invalidate or delete the account.

Procedure Step 1 Check whether the license for the SNMP NBI has been obtained. If not, the SNMP service process is not displayed on the System Monitor client. For details, see 4.5 Checking the License. Step 2 If there is a license for the SNMP NBI, redeploy the NBI or restart the U2000. Then check for the SNMP Service process. Step 3 If the SNMP Service process is not running, contact your Huawei engineers. ----End

7.3.2 SNMP Service Process Fails to Be Started Symptom After the SNMP NBI is configured, the SNMP service process fails to be started.

Possible Causes Port 9812 for configuring the SNMP NBI is occupied by other processes. The V3 User is blank when use the SNMP v3.

CAUTION Do not use the default ports of the SNMP protocol (port 161 and port 162) to configure the SNMP NBI, because these they are occupied by other processes. Refer to chapter "U2000 Port List" in the iManager U2000 Administrator Guide and the iManager U2000 Planning Guide before you configure ports for the SNMP NBI.

Procedure Step 1 Check whether other processes are using the port of the SNMP service. Run the netstat -an command to view the service ports opened by the system. l On the Solaris or Linux OS, run the netstat -an | grep port_number command to view the status of a specified port. For example, run the netstat -an | grep 6666 command to view the status of port 6666. l In the Windows OS, run the netstat -an | find "port_number" command to view the status of a specified port. For example, run the netstat -an | find "6666" command to view the status of port 6666. NOTE

If any router or firewall is located on the network between the U2000 and the OSS, you must check the ports used by the U2000 and the OSS and ensure that these ports can be opened for normal communication.

7 Maintaining the SNMP NBI

Possible Causes l

The following parameters are incorrect when the SNMP NBI is deployed. – Send Trap address/port in SNMP Agent – NMS receive Trap address/port in Third-part NMS

l

The request transmit port on the OSS and the request receive port on the U2000 are disabled on the firewall, so they cannot communicate with other. – The request transmit port on the OSS is 6666 by default. – The request receive port on the U2000 is 6666 by default.

Procedure Step 1 After confirming the previous parameters with OSS engineers, log in to the Msuite MSuite client and reconfigure the SNMP NBI based on the confirmation. Step 2 Check whether the request transmit port on the OSS and the request receive port on the U2000 are enabled on the firewall; otherwise they cannot communicate with each other. ----End

7.3.6 Acknowledge or Un-acknowledge or Clear Alarms Fails Symptom The NMS/OSS can receive heartbeat and alarms, but active alarms cannot be acknowledged or unacknowledged or cleared.

Possible Causes l

The alarm have converted to the history alarm.

l

The dependent services are down, such as log service and fault service.

l

Version mismatch of the MIB file. – The U2000-T MIB cannot acknowledged or unacknowledged or cleared alarms. – The MIB file that the NMS/OSS loaded is mismatch with the U2000.

Procedure Step 1 Log in the client of U2000, browse the history alarms. View the serial number is exist. If the serial number is exist, the alarm is converted to history alarm, then you cannot acknowledge, unacknowledge and clear history alarms. Step 2 Log in the client of U2000 System Monitor, view whether the log service and fault service are running normally. If not started, please restart the processes. Step 3 View whether the MIB file the U2000 loaded is correct. 1.

WARNING l Trap mode: A received alarm is reported immediately regardless of whether the OSS returns a response to the previous alarm reporting. l Inform mode: A received alarm is reported immediately after the OSS returns a response to the previous alarm reporting or the retried times is excessed. In this mode, if the parameters configured for the OSS are incorrect, the SNMP agent tries connecting to the OSS for many times. This will occupy a large number of resources. As a result, the efficiency of the SNMP agent is reduced. Therefore, exercise caution when you set this parameter to Inform. l The SNMPv1 supports the Trap mode only. Parameter

NOTE

The following two correlative alarms are involved by the location relationships between correlative alarms and root alarms: l NE-level correlative alarms: Correlative alarms and root alarms are generated on the same NE. l Trail-based correlative alarms: Correlative alarms and root alarms are generated on different upstream and downstream NEs connected by services. After alarm correlation rules are enabled on the U2000, the NBIs report correlative alarms based on the alarm correlation analysis results on the U2000 and different NBIs have different rules for reporting correlative alarms. The SNMP NBI supports only trail-based correlative alarms.

B.2.7 Engineering Alarm During engineering commissioning or service cutover, a large number of alarms are generated on NEs. If you set the NEs in engineering maintenance state, generated alarms are displayed as engineering alarms. You can specify whether to report the engineering alarms.

E Service Ports Description

E.1 Notes and Precautions In the practical communication process, the source (the server) and the sink (the client) use relevant ports. Usually you only need to specify the source port, and the sink port is dynamically created. Note the following during the project implementation: l

The service ports used by the NMS should not be closed. Run the following command to view the system service ports:

netstat -an

l

If there are routers or firewalls between the source and the sink, check all ports used by the source and the sink. Make sure that these ports can be normally turned up to support the communication between the source and sink.

E.2 Port Used Between the U2000 Server and the OSS This topic describes the port used between the U2000 server and the OSS. If a firewall is deployed between the U2000 server and the OSS, ensure that any port on the OSS can set up connections with ports on the U2000 through the firewall. For ports used by the U2000, see U2000 Communication Port Matrix.
