Chapter 8 Configuring VLAN

This chapter introduces the following:

Overview

Command List

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 Description Application range

StandardVLAN

The Ethernet ports in a standard VLAN cancommunicates with each other, while theEthernet port of different standard VLANscannot.

It is used for the LANaccess and the LANsubtending servicesof the IPMB card.

SmartVLAN

A smart VLAN can contain multiple xDSLvirtual ports.

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

A smart VLAN can access multiple xDSLsubscribers, reducing the number of VLANsoccupied.

It is used for xDSLaccess services.

MUX VLAN

A MUX VLAN contains only one xDSL virtualport.

Service flows in different MUX VLANs areisolated.

There is a one-to-one mapping between theMUX VLAN and the access subscriber.Therefore, you can distinguish differentsubscribers by the VLAN tags.

It is used for xDSLaccess services.

SuperVLAN

A super VLAN is a layer-3 based VLAN.

A super VLAN consists of multiplesub-VLANs that can communicate with eachother at layer 3 through the ARP Proxy.

There are three types of sub-VLANs:standard VLAN, smart VLAN and MUXVLAN.

It saves IP addressesand increases theservice efficiency ofthe 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

Example

8-3

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

Example

To display the settings of VLAN 10 to VLAN 15, do as follows:

huawei(config)#display vlan

{ vlanid|all|number }:10

{ |to }:to

{ end-vlanid }:15

{ |vlantype|vlanattr }:

Note : STND-Port--standard port, SERV-Port--service virtual port

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 3virtual interface.

QinQ VLAN

A QinQ VLAN packet contains an internal VLAN tag of thesubscriber private network and an external VLAN tag allocated

by the UA5000. The QinQ VLAN can form a layer 2 VPN tunnelto transparently transmit services among private networks.

Stacking VLAN

A stacking VLAN packet contains an internal VLAN tag and anexternal VLAN tag. Both tags are assigned by the UA5000.

VLAN stacking is adopted for the upper BAS to realize dualVLAN authentication and increase the number of accesssubscribers.

In a network working in the layer-2 mode, the packets can beforwarded based on the VLAN tags and the MAC addresses. Inthis 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.

8-5

Note:

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

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

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

upstream interface for a VLAN

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 2

--------------------------------------------

Total: 2 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 MACaddress 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:


8/9



8-7

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: super

VLAN attribute: common

sub vlan number: 3

---------------------------------------------------------

VLAN Type Attribute STND-Port NUM SERV-Port NUM

---------------------------------------------------------

2 standard sub 1 0

3 MUX sub 1 0

4 smart sub 1 0

-------------------------------------------------------------------------

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:


9/9



8-8

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.
