Usage guidelines
After you execute this command, only packets whose TPID in the outermost VLAN tag is 0x8100 or the configured value are processed as VLAN-tagged packets.
When sending a packet, the interface sets the TPID value in the outermost VLAN tag to the configured value. If the packet includes two or more layers of VLAN tags, the interface sets the TPID values in the other VLAN tags to 0x8100.
Do not use this command in subinterface view.
Configurations made in the following interface views take effect on all subinterfaces:
· Layer 3 Ethernet interface view.
· Layer 3 aggregate interface view.
Examples
# Set the TPID value to 0x9100 in the outermost VLAN tag of VLAN-tagged packets received and sent by the subinterfaces of GigabitEthernet 2/1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1

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 2/1/1.10 to tag a multicast or broadcast packet with each VLAN tag in the range of 10 to 20.
# Enable Dot1q termination on subinterface GigabitEthernet 2/1/1.10 to terminate VLAN-tagged packets with outermost VLAN IDs in the range of 10 to 20.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1.10
[Sysname-GigabitEthernet2/1/1.10] vlan-type dot1q vid 10 to 20
# Enable GigabitEthernet 2/1/1.10 to transmit broadcast and multicast packets.
[Sysname-GigabitEthernet2/1/1.10] vlan-termination broadcast enable
· Configure GigabitEthernet 2/1/1.10 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.

vlan-termination broadcast ra
Use vlan-termination broadcast ra to enable an interface to transmit router advertisement (RA) multicast packets.
Use undo vlan-termination broadcast ra to disable an interface from transmitting RA multicast packets.
Syntax
vlan-termination broadcast ra
undo vlan-termination broadcast ra
Default
An ambiguous Dot1q or QinQ termination-enabled interface drops broadcast and multicast packets.

Usage guidelines
To transmit an RA 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.
As a best practice, use this command to enable an ambiguous Dot1q or QinQ termination-enabled interface to transmit RA multicast packets on an IPv6 network. This command prohibits transmission of broadcast packets and other types of multicast packets, and consumes less CPU resources than the vlan-termination broadcast enable command.
Examples
· Configure GigabitEthernet 2/1/1.10 to tag RA multicast packets with each VLAN tag in the range of 10 to 20.
# Enable Dot1q termination on GigabitEthernet 2/1/1.10 to terminate VLAN-tagged packets with outermost VLAN IDs in the range of 10 to 20.

· Configure GigabitEthernet 2/1/1.10 to tag RA multicast packets 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 2/1/1.10 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.

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.
loose: Configures the subinterface to terminate packets that include one or more layers of VLAN tags.
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 2/1/1.1 to terminate VLAN-tagged packets with outermost VLAN IDs in the range of 2 to 100.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1.1
[Sysname-GigabitEthernet2/1/1.1] vlan-type dot1q vid 2 to 100
# Configure GigabitEthernet 2/1/1.1 to terminate VLAN-tagged packets that include one or more layers of VLAN tags with the outermost VLAN ID 2.

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 } [ loose ]
undo vlan-type dot1q vid vlan-id-list second-dot1q { vlan-id-list | any } [ loose ]
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.
loose: Configures the interface to receive and terminate packets that include two or more layers of VLAN tags.
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.
