QinQ commands

This feature is supported only on the following ports:

 

‌

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

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 1/0/1. Then, verify that QinQ is enabled on the interface.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] qinq enable

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

Interface

 GigabitEthernet1/0/1

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

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] qinq enable

[Sysname-GigabitEthernet1/0/1] quit

[Sysname] interface gigabitethernet 1/0/3

[Sysname-GigabitEthernet1/0/3] qinq enable

[Sysname-GigabitEthernet1/0/3] display qinq

Interface

 GigabitEthernet1/0/1

qinq ethernet-type (interface view)

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

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

Syntax

qinq ethernet-type service-tag hex-value

undo qinq ethernet-type service-tag

Default

The interface-level TPID value in SVLAN and CVLAN tags equals the global TPID value.

Views

Layer 2 Ethernet interface view

Layer 2 aggregate interface view

Predefined user roles

network-admin

Parameters

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

hex-value: Sets a hexadecimal TPID value in the range of 600 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.

Examples

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

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

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

qinq ethernet-type (system view)

Use qinq ethernet-type to set the TPID value in SVLAN or CVLAN tags globally.

Use undo qinq ethernet-type to restore the default TPID value in SVLAN or CVLAN tags globally.

Syntax

qinq ethernet-type customer-tag hex-value

undo qinq ethernet-type customer-tag

Default

The TPID value in both SVLAN and CVLAN tags is 8100 in hexadecimal notation.
