QinQ commands

This document uses the following terms:

·     CVLAN—Customer network VLANs, also called inner VLANs, refer to VLANs that a customer uses on the private network.

·     SVLAN—Service provider network VLANs, also called outer VLANs, refer to VLANs that a service provider uses to transmit VLAN tagged traffic for customers.

display qinq

Use display qinq to display QinQ-enabled interfaces.

Syntax

display qinq [ interface interface-type interface-number ]

Views

Any view

Predefined user roles

network-admin

network-operator

mdc-admin

mdc-operator

Parameters

interface interface-type interface-number: Specifies an interface by its type and number. If you do not specify an interface, this command displays all QinQ-enabled interfaces.

Usage guidelines

If QinQ is not enabled on any interfaces, this command does not provide any output.

Examples

# Enable QinQ on GigabitEthernet 1/2/0/1. Then, verify that QinQ is enabled on the interface.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/2/0/1

[Sysname-GigabitEthernet1/2/0/1] qinq enable

[Sysname-GigabitEthernet1/2/0/1] display qinq interface gigabitethernet 1/2/0/1

Interface

 GigabitEthernet1/2/0/1

# Enable QinQ on GigabitEthernet 1/2/0/1 and GigabitEthernet 1/2/0/3. Then, verify that QinQ is enabled on the interfaces.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/2/0/1

[Sysname-GigabitEthernet1/2/0/1] qinq enable

[Sysname-GigabitEthernet1/2/0/1] quit

[Sysname] interface gigabitethernet 1/2/0/3

[Sysname-GigabitEthernet1/2/0/3] qinq enable

[Sysname-GigabitEthernet1/2/0/3] display qinq

Interface

 GigabitEthernet1/2/0/1

 GigabitEthernet1/2/0/3

undo qinq enable

Default

QinQ is disabled on interfaces.

display qinq

qinq ethernet-type (interface view)

Use qinq ethernet-type to set the TPID value in SVLAN tags on an interface.

Use undo qinq ethernet-type to restore the default TPID value in SVLAN tags on an interface.

Syntax

qinq ethernet-type service-tag hex-value

undo qinq ethernet-type service-tag

Default

If the device supports global TPID configuration, the interface-level TPID value in SVLAN tags equals the global TPID value.

If the device does not support global TPID configuration, the TPID value in both SVLAN tags is 8100 in hexadecimal notation.

Predefined user roles

mdc-admin

Parameters

service-tag: Sets the TPID value in the SVLAN tag.

hex-value: Sets a hexadecimal TPID value in the range of 1 to ffff, excluding the reserved EtherType values listed in Table 1.

Table 1 Reserved EtherType values

Usage guidelines

For a port, the TPID value set in interface view applies preferentially over the TPID value set in system view. You can set the TPID value only to 8100 or 9100 in hexadecimal notation.

Examples

# Set the TPID value in the SVLAN tags to 9100 (hexadecimal) on GigabitEthernet 1/2/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/2/0/1

[Sysname-GigabitEthernet1/2/0/1] qinq ethernet-type service-tag 9100
