QinQ commands

Do not configure QinQ and Ethernet service instance-to-VSI binding on the same Layer 2 Ethernet interface or Layer 2 aggregate interface. Do not configure QinQ on a Layer 2 Ethernet interface or Layer 2 aggregate interface that acts as the source interface of a VXLAN tunnel. Otherwise, these features might not take effect. For more information about VXLAN and VSI, see VXLAN Configuration Guide.

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.

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.

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

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

Interface

 Ten-GigabitEthernet1/0/1

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

The TPID value in SVLAN tags is 8100 in hexadecimal notation.

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.

Usage guidelines

A port without QinQ enabled uses the SVLAN TPID to match incoming tagged frames. The port modifies the TPID in the SVLAN tag of outgoing frames as the configured value.

Examples

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

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/0/1

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

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.

Views

Predefined user roles

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.

You can repeat this command to add VLANs to the list of 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.

·     If you use both transparent VLANs and VLAN mappings on an interface, the transparent VLANs cannot be the following VLANs:

¡     Original or translated VLANs of one-to-one or one-to-two VLAN mappings.

¡     Original or translated outer VLANs of two-to-two VLAN mappings.

Examples

# Configure Ten-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 Ten-GigabitEthernet 1/0/1, and configure the port to transparently transmit frames from VLAN 2.
