dot1q vid vlan-id: Specifies the outermost VLAN ID in VLAN-tagged packets that are terminated by subinterfaces. The value range for the vlan-id argument is 1 to 4094.

second-dot1q vlan-id: Specifies the outermost Layer 2 VLAN ID in VLAN-tagged packets that are terminated by subinterfaces. The value range for the vlan-id argument is 1 to 4094.

Usage guidelines

This command displays VLAN termination configurations on subinterfaces of a specifed main interface.

This command is available only for VLAN Dot1q termination and VLAN QinQ termination:

· This command displays information about Dot1q termination-enabled subinterfaces when the dot1q vid vlan-id parameter is specified.

· This command displays information about QinQ termination-enabled subinterfaces when both the dot1q vid vlan-id and second-dot1q vlan-id parameters are specified.

Examples

# Display VLAN termination information on subinterfaces of Layer 3 aggregate interface Route-Aggregation 1. The outermost VLAN ID for the subinterfaces is 5.

<Sysname> display subinterface route-aggregation 1 dot1q vid 5

Subinterface Route-Aggregation1.1:

Service VLAN: 5

# Display VLAN termination information on subinterfaces of Layer 3 aggregate interface Route-Aggregation 1. The outermost Layer 1 and Layer 2 VLAN IDs for the subinterfaces are 2 and 3, respectively.

Subinterface	VLAN termination configuration on a subinterface.
Current state	Link state of the subinterface: · UP—The interface is both administratively and physically up. · DOWN—The interface is administratively and physically down (possibly because the subinterface has been shut down by using the shutdown command or the physical link of the main interface has failed).
Service VLAN	This field indicates the outermost layer VLAN for VLAN Dot1q termination.
Customer VLAN	This field indicates Layer 2 VLAN for VLAN QinQ termination. This field displays only when the second-dot1q argument is specified.

Parameters

interface-type: Specifies an interface type.

interface-number.subnumber: Specifies a subinterface by its number. The interface-number argument specifies the main interface number, and the subnumber argument specifies a subinterface number.

slot slot-number: Specifies a card by its slot number. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. (In IRF mode.)

Usage guidelines

This command displays user VLAN information on a subinterface only if the following conditions exist:

· The user-vlan dot1q vid or user-vlan dot1q vid second-dot1q command has been configured on the subinterface.

· Online users are present on the subinterface.

When you specify the slot slot-number option, following these restrictions and guidelines:

· If member ports of an aggregation group belong to different slots, user this option to specify a slot. If you do not specify this option, the command displays user VLAN information on the slot that hosts the aggregation member port with the smallest port number. The Port Number field of the display link-aggregation member-port command output displays the port number of an aggregation member port.

· To display user VLAN information on other types of subinterfaces, do not specify this option.

Examples

# Display user VLAN information on Layer 3 Ethernet subinterface Ten-GigabitEthernet3/1/1.1.

<Sysname> display user-vlan interface ten-gigabitethernet 3/1/1.1

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.

Configurations made on a Layer 3 Ethernet interface or Layer 3 aggregate interface take effect on all subinterfaces of the interface.

Examples

# Set the TPID value to 0x9100 in the outermost VLAN tag of VLAN-tagged packets received and sent by the subinterfaces of Ten-GigabitEthernet 3/1/1.

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.

This command is not supported on the device operating in SDN-WAN mode.

After you configure user VLAN QinQ termination on a subinterface of a Layer 3 aggregate interface with port mirroring configured, port mirroring does not take effect if no user accesses the network through the Layer 3 aggregate interface. For more information about port mirroring, see Network Management and Monioring Configuration Guide.

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.

This command and the vlan-type dot1q vid second-dot1q command are mutually exclusive on the same subinterface.

Usage guidelines

IMPORTANT:

This command affects system performance. If system performance is seriously affected by this command, execute the undo form of this command to remove the command configuration.

To transmit a broadcast or multicast packet, the interface starts a traversal over all the VLAN IDs specified for Dot1q/QinQ termination. It copies the packet and tags each copy with VLAN IDs, until all combinations of VLAN IDs are traversed.

Examples

· Configure Ten-GigabitEthernet 3/1/1.10 to tag a multicast or broadcast packet with each VLAN tag in the range of 10 to 20.

Usage guidelines

To transmit an RA multicast packet, the interface starts a traversal over all the VLAN IDs specified for Dot1q/QinQ termination. It copies the packet and tags each copy with VLAN IDs, until all combinations of VLAN IDs are traversed.

You must 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 Ten-GigabitEthernet 3/1/1.10 to tag RA multicast packets with each VLAN tag in the range of 10 to 20.

Usage guidelines

After you modify VLAN termination on a subinterface, the subinterface automatically restarts. In some networks (for example, networks using IPoE or PPPoE connections), the subinterface restart logs off online users. To prevent the subinterface restart and protect the online user state, enable user mode of VLAN termination before you modify VLAN termination on the subinterface.

After you enable user mode of VLAN termination and modify VLAN termination on a subinterface, clear entries of VLANs that are no longer terminated by the subinterface. If you do not clear these entries, running services might be affected.

For example, after you modify VLAN termination on a subinterface, perform the following tasks for the subinterface:

· Use the reset arp interface command in user view to clear all ARP entries.

· Use the reset ipv6 neighbors interface command in user view to clear all dynamic neighbors.

For more information about the reset arp and reset ipv6 neighbors commands, see ARP and IPv6 basics commands in Layer 3—IP Services Command Reference.
