second-dot1q

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

Use undo second-dot1q to disable QinQ termination on an interface.

Syntax

second-dot1q { vlan-id-list | any }

undo second-dot1q { vlan-id-list | any }

Default

QinQ termination is disabled on a VLAN interface.

Parameters

vlan-id-list: Specifies a space-separated list of up to 10 Layer 2 VLAN ID items. Each item specifies a Layer 2 VLAN ID or a range of Layer 2 VLAN IDs in the form of vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to 4094. The value for the vlan-id2 argument must be equal to or greater than the value for the vlan-id1 argument.

any: Specifies all values between 1 and 4094.

Usage guidelines

When you execute this command, the Layer 1 VLAN ID of VLAN-tagged packets that can be terminated by the interface is the interface number. This Layer 1 VLAN ID is not configurable.

Examples

# Configure VLAN-interface 10 to terminate VLAN-tagged packets with Layer 2 VLAN IDs in the range of 10 to 20.

<Sysname> system-view

[Sysname] interface vlan-interface 10

[Sysname-Vlan-interface10] second-dot1q 10 to 20

[Sysname-Vlan-interface10] quit

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

[Sysname] interface vlan-interface 12

[Sysname-Vlan-interface12] second-dot1q 100

[Sysname-Vlan-interface12] quit

# Configure VLAN-interface 100 to terminate VLAN-tagged packets with any Layer 2 VLAN IDs.

[Sysname] interface vlan-interface 100

[Sysname-Vlan-interface100] second-dot1q any

The following table describes the configuration results:

 

VLAN interface	Layer 1 VLAN ID of VLAN-tagged packets that the VLAN interface can terminate	Layer 2 VLAN IDs of VLAN-tagged packets that the VLAN interface can terminate
VLAN-interface 10	10	10–20
VLAN-interface 12	12	100
VLAN-interface 100	100	1–4094

 

vlan-termination broadcast enable

Use vlan-termination broadcast enable to enable an interface to transmit broadcasts and multicasts.

Use undo vlan-termination broadcast enable to restore the default.

Syntax

vlan-termination broadcast enable

undo vlan-termination broadcast enable

Default

An ambiguous Dot1q or QinQ termination-enabled interface drops broadcast and multicast packets.

Usage guidelines

	CAUTION: This command affects system performance. If the system performance is seriously affected by this command, remove this command.

 

Use this command when ambiguous Dot1q or QinQ termination is enabled on an interface.

To transmit a broadcast or multicast packet, the interface starts a traversal over the VLAN IDs specified for ambiguous termination. It copies the packet and tags each copy with a VLAN ID, until all VLAN IDs in the specified range are traversed. For example, when ambiguous QinQ termination is configured, both layers of VLAN ID ranges are traversed.

Examples

·     Configure GigabitEthernet 1/0/1.10 to tag a multicast or broadcast packet with each VLAN tag in the range of 10 to 20.

# Enable Dot1q termination on subinterface GigabitEthernet 1/0/1.10 to terminate VLAN-tagged packets with outermost VLAN IDs in the range of 10 to 20.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1.10

[Sysname-GigabitEthernet1/0/1.10] vlan-type dot1q vid 10 to 20

# Enable GigabitEthernet 1/0/1.10 to transmit broadcast and multicast packets.

[Sysname-GigabitEthernet1/0/1.10] vlan-termination broadcast enable

·     Configure GigabitEthernet 1/0/1.10 to tag a multicast or broadcast packet with each Layer 1 VLAN ID and each Layer 2 VLAN ID. The Layer 1 and Layer 2 VLAN IDs are in the range of 300 to 400 and 500 to 600, respectively.

# Configure GigabitEthernet 1/0/1.10 to terminate VLAN-tagged packets whose Layer 1 and Layer 2 VLAN IDs are in the range of 300 to 400 and 500 to 600, respectively.

# Enable GigabitEthernet 1/0/1.10 to transmit broadcast and multicast packets.

[Sysname-GigabitEthernet1/0/1.10] vlan-termination broadcast enable

·     Configure VLAN-interface 10 to tag a multicast or broadcast packet with two layers of VLAN IDs. The Layer 1 VLAN ID is 10. The Layer 2 VLAN ID is each VLAN ID in the range of 10 to 20.

# Configure VLAN-interface 10 to terminate VLAN-tagged packets with Layer 2 VLAN IDs in the range of 10 to 20.

Use undo vlan-type dot1q default to disable default termination on a subinterface.

Syntax

vlan-type dot1q default

undo vlan-type dot1q default

Default

Default termination is disabled on a subinterface.

Usage guidelines

This command enables the subinterface to process packets that cannot be terminated by other subinterfaces on the same main interface.

Examples

# Enable default termination on GigabitEthernet 1/0/1.1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1.1

vlan-type dot1q untagged

Use vlan-type dot1q untagged to enable untagged termination on a subinterface.

Use undo vlan-type dot1q untagged to disable untagged termination on a subinterface.

Syntax

vlan-type dot1q untagged

undo vlan-type dot1q untagged

Default

Untagged termination is disabled on a subinterface.

Usage guidelines

This command enables the subinterface to process untagged packets.

Examples

# Enable untagged termination on GigabitEthernet 1/0/1.1.

<Sysname> system-view

Use undo vlan-type dot1q vid to disable Dot1q termination on a subinterface.

Syntax

vlan-type dot1q vid vlan-id-list

undo vlan-type dot1q vid vlan-id-list

Default

Dot1q termination is disabled on a subinterface.

Views

Parameters

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

Usage guidelines

You cannot configure multiple subinterfaces under an Ethernet interface to terminate VLAN-tagged packets from the same VLAN. The VLAN ID ranges specified by the vlan-id-list argument for different subinterfaces cannot overlap.

Examples

# Configure GigabitEthernet 1/0/1.1 to terminate VLAN-tagged packets with outermost VLAN IDs in the range of 2 to 100.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1.1

[Sysname-GigabitEthernet1/0/1.1] vlan-type dot1q vid 2 to 100

The following table describes the configuration results:

 

Subinterface	Outermost VLAN ID of packets that can be terminated	Whether packets to be terminated include more than one layer of VLAN tags
GigabitEthernet 1/0/1.1	2	Yes

 

vlan-type dot1q vid second-dot1q

Use vlan-type dot1q vid second-dot1q to enable QinQ termination on a subinterface, and specify the outermost two layers of VLAN IDs of VLAN-tagged packets that can be terminated by the subinterface.

Use undo vlan-type dot1q vid second-dot1q to disable QinQ termination on a subinterface.

Syntax

vlan-type dot1q vid vlan-id-list second-dot1q { vlan-id-list | any }

undo vlan-type dot1q vid vlan-id-list second-dot1q { vlan-id-list | any }

Default

QinQ termination is disabled on a subinterface.

Parameters

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

any: Specifies all values between 1 and 4094.

Usage guidelines

Two subinterfaces of the same Ethernet interface cannot terminate packets that include the same two layers of VLAN IDs. If you configure the subinterfaces to terminate the same Layer 1 VLAN ID, make sure their Layer 2 VLAN ID ranges do not overlap. If you specify both any and vlan-id-list as the respective Layer 2 VLAN ID ranges of the subinterfaces, the any keyword does not include the VLAN IDs specified by vlan-id-list.

Examples

# Enable QinQ termination on the Layer 3 Ethernet subinterfaces, and configure each subinterface to terminate VLAN-tagged packets with the specified Layer 1 and Layer 2 VLAN IDs.
