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.

Use display qinq to display QinQ-enabled interfaces.

Syntax

display qinq [ interface interface-type interface-number ]

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.

qinq transparent-vlan

Use qinq transparent-vlan to enable transparent transmission for a list of VLANs on a port.

Use undo qinq transparent-vlan to disable transparent transmission for a list of VLANs on a port.

Syntax

qinq transparent-vlan vlan-id-list

undo qinq transparent-vlan { vlan-id-list | all }

Default

Transparent transmission is disabled for all VLANs on a port.

Views

Predefined user roles

mdc-admin

Parameters

vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a single VLAN ID or a VLAN ID range in the form of vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to 4094. The end VLAN ID must be equal to or greater than the start VLAN ID.

all: Specifies all VLANs.

Usage guidelines

By default, QinQ tags all incoming frames with the PVID on a port. This command disables QinQ to tag incoming traffic from a list of VLANs. These VLANs are called transparent VLANs.

To ensure successful transmission for a transparent VLAN, follow these configuration guidelines:

·     Set the link type of the port to trunk or hybrid, and assign the port to the transparent VLAN.

·     Do not configure any other VLAN manipulation actions for the transparent VLAN on the port.

·     Make sure all ports on the traffic path permit the transparent VLAN to pass through.

Examples

# Configure GigabitEthernet 1/0/1 as a trunk port, and assign the port to VLAN 2, VLAN 3, and VLANs 50 through 100. Enable QinQ on GigabitEthernet 1/0/1, and configure the port to transparently transmit frames from VLAN 2.
