QinQ termination configuration commands

Support for QinQ termination commands depends on the device model. For more information, see About the H3C Access Controllers Command References.

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.

qinq ethernet-type

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

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

Syntax

qinq ethernet-type hex-value

undo qinq ethernet-type

Default

The TPID value in SVLAN tags is 0x8100.

Views

Layer 2 Ethernet interface view, Layer 2 aggregate interface view

Default command level

2: System level

Parameters

hex-value: Sets a hexadecimal TPID value in the range of 0x0001 to 0xFFFF, excluding the reserved protocol type values listed in Table 1.

Table 1 Reserved protocol type values

Usage guidelines

The configuration made in Layer 2 Ethernet interface view takes effect only on the port.

The configuration made in Layer 2 aggregate interface view takes effect on the aggregate interface and its member ports.

Examples

# Set the TPID value in SVLAN tags to 0x9100 on Ten-GigabitEthernet 2/0/1.

<Sysname> system-view

[Sysname] interface Ten-GigabitEthernet 2/0/1

[Sysname-Ten-GigabitEthernet 2/0/1] qinq ethernet-type 9100

second-dot1q

Use second-dot1q to enable QinQ termination and specify the Layer 2 VLAN ID of the VLAN-tagged packets that can be terminated on an interface.

Use undo second-dot1q to restore the default.

Syntax

second-dot1q vlan-id

undo second-dot1q vlan-id

Default

QinQ termination is disabled.

Views

VLAN interface view

Default command level

2: System level

Parameters

vlan-id: Specifies a Layer 2 VLAN ID in the range of 1 to 4094.

Usage guidelines

The Layer 1 VLAN ID of the VLAN-tagged packets that can be terminated by the VLAN interface is the number of the VLAN interface. This Layer 1 VLAN ID is not configurable.

When you delete the Layer 2 VLAN ID specified in QinQ termination on an interface, the following events will occur:

·     The interface will restart.

·     The ARP entry of the interface will be deleted.

Examples

# Configure VLAN-interface 12 to terminate VLAN-tagged packets with Layer 2 VLAN ID 100.

<Sysname> system-view

[Sysname] interface vlan-interface 12

[Sysname-Vlan-interface12] second-dot1q 100
