Configuring a VLAN

8.1 Overview There are four VLAN types, namely standard VLAN, smart VLAN, MUX VLAN and super VLAN. Table 8–1 gives a detailed description of the four VLAN types. Table 8–1 VLAN type and application range VLAN type Standard VLAN

Description The Ethernet ports in a standard VLAN can communicates with each other, while the Ethernet port of different standard VLANs cannot.

Application range It is used for the LAN access and the LAN subtending services of the IPMB card.

A smart VLAN can contain multiple xDSL virtual ports. Smart VLAN

Service flows of the xDSL virtual ports are isolated. In addition, services flows in different smart VLANs are also isolated.

It is used for xDSL access services.

A smart VLAN can access multiple xDSL subscribers, reducing the number of VLANs occupied. A MUX VLAN contains only one xDSL virtual port. MUX VLAN

Service flows in different MUX VLANs are isolated. There is a one-to-one mapping between the MUX VLAN and the access subscriber. Therefore, you can distinguish different subscribers by the VLAN tags.

It is used for xDSL access services.

A super VLAN is a layer-3 based VLAN. Super VLAN

A super VLAN consists of multiple sub-VLANs that can communicate with each other at layer 3 through the ARP Proxy. There are three types of sub-VLANs: standard VLAN, smart VLAN and MUX VLAN.

It saves IP addresses and increases the service efficiency of the IP addresses.

8.3 Configuring a VLAN This section shows how to configure a VLAN.

8.3.1 Adding a VLAN To add one or more VLANs and specify the VLAN types, use the vlan command. Example To add a standard VLAN (VLAN ID=2), a smart VLAN (VLAN ID=3), a MUX VLAN (VLAN ID=4) and a super VLAN (VLAN ID=5), do as follows: huawei(config)#vlan { vlanid|attrib }:2 { vlantype|to }:standard huawei(config)#vlan 3 mux huawei(config)#vlan 4 smart huawei(config)#vlan 5 super

To add MUX VLANs in batches, with VLAN IDs from 10 to 15, do as follows: huawei(config)#vlan { vlanid|attrib }:10 { vlantype|to }:to { end-vlanid }:15 { vlantype }:mux It will take several minutes, and console may be timeout , please use command idle-timeout to set time limit Are you sure to add VLANs? (y/n)[n]:y The total of the added vlan is 6

8.3.2 Querying the VLAN Settings To query the settings of one or all VLANs, use the display vlan command. Example To display the settings of VLAN 20, do as follows: huawei(config)#display vlan 20 { |to }: Command: display vlan 20 VLAN ID: 20 VLAN type: MUX VLAN attribute: common -----------------------------F/S /P

8.3.3 Configuring the VLAN Attributes The VLAN supports three attributes: Common, QinQ and Stacking. Table 8–3 shows the details of the VLAN attributes. Table 8–3 VLAN attributes VLAN Attributes

Application

Common VLAN

A common VLAN acts as a common layer 2 VLAN or the layer 3 virtual interface.

QinQ VLAN

A QinQ VLAN packet contains an internal VLAN tag of the subscriber private network and an external VLAN tag allocated by the UA5000. The QinQ VLAN can form a layer 2 VPN tunnel to transparently transmit services among private networks. A stacking VLAN packet contains an internal VLAN tag and an external VLAN tag. Both tags are assigned by the UA5000.

Stacking VLAN

VLAN stacking is adopted for the upper BAS to realize dual VLAN authentication and increase the number of access subscribers. In a network working in the layer-2 mode, the packets can be forwarded based on the VLAN tags and the MAC addresses. In this way, the UA5000 offers the multi-ISP wholesale service.

To configure the attributes for a specified VLAN, use the vlan attrib command. The default attribute of a VLAN is common. Example To configure the attributes of a VLAN (VLAN ID=2) as QinQ, do as follows: huawei(config)#vlan attrib 2 q-in-q

To restore the default attributes of a VLAN, use the undo vlan attrib command.

Chapter 8 Configuring VLAN

Note: These VLANs cannot be configured as the QinQ or stacking VLANs: z

A VLAN which is configured with a virtual port or has enabled the layer 3 function , such as the super VLAN or the sub VLAN

z

The system default VLAN (VLAN ID=1), and the default VLAN which is set as the upstream interface for a VLAN

z

A standard VLAN

8.3.4 Deleting a VLAN To delete a VLAN, use the undo vlan command. Example To delete VLAN 15, do as follows: huawei(config)#undo vlan 15

To delete a VLAN, you must delete all the ports in the VLAN.

8.3.5 Adding a Port to a VLAN To add a port to one or more VLANs, use the port vlan command. Example To add port 0/2/1 to VLAN 2, do as follows: huawei(config)#port vlan { vlanid }:2 { frame/slot|to }:0/2 { portlist }:1

8.3.6 Querying the VLAN Settings of a Port To query the VLAN settings and the default VLAN of a port, use the display port vlan command. Example To query the VLAN settings of port 0/2/1, do as follows: huawei(config)#display port vlan { frame/slot/port|frame/slot }:0/2/1 --------------------------------------1

Native VLAN: 1

8.3.7 Deleting a Port from a VLAN To delete a port from a VLAN, use the undo port vlan command. Example To delete port 0/2/1 from VLAN 2, do as follows: huawei(config)#undo port vlan { vlanid }:2 { frame/slot|to }:0/2 { portlist }:1

Note: If a VLAN is the default VLAN of a port, or a VLAN is referenced by the static MAC address entry of a port, the port cannot be deleted from the VLAN.

8.3.8 Configuring a Layer 3 Virtual Interface for a VLAN To configure a layer 3 virtual interface for a VLAN and enter the interface configuration mode, use the interface vlanif command. To delete a layer 3 virtual interface from a VLAN, use the undo interface vlanif command.

Note: A VLAN which is configured with a layer 3 virtual interface cannot be added to a super VLAN as a sub-VLAN.

8.3.9 Configuring a Super VLAN After creating a super VLAN using the vlan command, you can configure it as shown below.

I. Adding sub-VLANs to a super VLAN To add multiple sub-VLANs to a super VLAN, use the supervlan command. The sub-VLANs must exist and can be the standard VLAN, smart VLAN and MUX VLAN. Example To add the standard VLAN (VLAN ID=2), MUX VLAN (VLAN ID=3) and smart VLAN (VLAN ID=4) to the super VLAN (VLAN ID=5), do as follows: Huawei Technologies Proprietary 8-6

Operation Manual – IPM Volume UA5000 Universal Access Unit

Chapter 8 Configuring VLAN

huawei(config)#supervlan 5 { subvlan }:subvlan { vlanid }:2 { |to }:to { end-vlanid }:4 It will take several minutes, and console may be timeout, please use command idle-timeout to set time limit Are you sure to add subvlans? (y/n)[n]:y

The total of the VLAN(s) having been processed is 3

The sum of subvlan(s) which has been added successfully is:

3

Example To query the settings of the super VLAN (VLAN ID=5), do as follows: huaweiconfig)#display vlan { vlanid|all|number }:5 { |to }: VLAN ID: 5 VLAN type:

Note: QinQ or Stacking VLANs cannot be added to a super VLAN as sub-VLANs.

II. Deleting a sub-VLAN from a super VLAN To delete a sub-VLAN from a super VLAN, use the undo supervlan command. Example To delete the sub-VLAN (VLAN ID=2) from the super VLAN (VLAN ID=5), do as follows: Huawei Technologies Proprietary 8-7

Operation Manual – IPM Volume UA5000 Universal Access Unit

Chapter 8 Configuring VLAN

huawei(config)#undo supervlan 5 subvlan 2

III. Configuring an IP address for the layer 3 virtual interface of a super VLAN To configure an IP address for the layer 3 virtual interface of a super VLAN, use the ip address command. All sub-VLANs share the IP address, which saves the IP address resources. Example To configure the IP address of the layer 3 virtual interface of the super VLAN (VLAN ID=5) as 10.1.1.1/24, do as follows: huawei(config)#interface vlanif 5 huawei(config-if-Vlanif5)#ip address { ip_addr }:10.1.1.1 { ip_addr|integer }:24 { |sub }:

Note: The layer 3 forwarding function of a super VLAN is implemented through the ARP Proxy. Therefore, you must enable the ARP proxy function to let the sub-VLANs in a super VLAN communicate with each other.
