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:

· To display user VLAN information on a Layer 3 Ethernet subinterface, do not specify this option.

· If member ports of an aggregation group belong to different cards, user this option to specify a card. If you do not specify this option, the command displays user VLAN information on the card 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.

Examples

# Display user VLAN information on Layer 3 Ethernet subinterface GigabitEthernet 3/1/1.1.

Usage guidelines

This command is not available on the following interfaces:

· Layer 3 Ethernet interfaces on the CSPC cards (except CSPC-GE16XP4L-E, CSPC-GE24L-E, and CSPC-GP24GE8XP2L-E) and CMPE-1104 cards.

· Layer 3 aggregate interfaces that have member ports on the CSPC cards (except CSPC-GE16XP4L-E, CSPC-GE24L-E, and CSPC-GP24GE8XP2L-E) and CMPE-1104 cards.

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.

· L3VE interface view.

Configurations made in VLAN interface view take effect on the VLAN interface.

For more information about L3VE interfaces, see L2VPN access to L3VPN or IP backbone configuration in MPLS Configuration Guide.

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.

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

This command is not available on the subinterfaces of the following interfaces:

· Layer 3 Ethernet interfaces on the CSPC cards (except CSPC-GE16XP4L-E, CSPC-GE24L-E, and CSPC-GP24GE8XP2L-E) and CMPE-1104 cards.

The outermost VLAN ID ranges specified by the vlan-id-list argument for different subinterfaces of a main interface cannot overlap.

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

This command is not available on the subinterfaces of the following interfaces:

· Layer 3 Ethernet interfaces on the CSPC cards (except CSPC-GE16XP4L-E, CSPC-GE24L-E, and CSPC-GP24GE8XP2L-E) and CMPE-1104 cards.

· Layer 3 aggregate interfaces that have member ports on the CSPC cards (except CSPC-GE16XP4L-E, CSPC-GE24L-E, and CSPC-GP24GE8XP2L-E) and CMPE-1104 cards.

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.

The outermost VLAN IDs cannot overlap if this command and the vlan-type dot1q vid second-dot1q command are configured on subinterfaces of the same main interface.

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

Examples

# Enable user VLAN QinQ termination on GigabitEthernet3/1/1.1. Configure the interface to terminate VLAN-tagged packets with Layer 1 VLAN IDs in the range of 1 to 100 and Layer 2 VLAN IDs in the range of 500 to 600.

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.

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

# Enable Dot1q termination on GigabitEthernet 3/1/1.10 to terminate VLAN-tagged packets with outermost VLAN IDs 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.

On an IPv6 network, you must use this command to enable an ambiguous Dot1q or QinQ termination-enabled interface to transmit RA multicast packets. 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 3/1/1.10 to tag RA multicast packets with each VLAN tag in the range of 10 to 20.

# Enable Dot1q termination on GigabitEthernet 3/1/1.10 to terminate VLAN-tagged packets with outermost VLAN IDs 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. For example, use the reset arp interface command in user view to clear all ARP entries for a subinterface after you modify VLAN termination on it. If you do not clear these entries, running services might be affected. For more information about the reset arp command, see ARP commands in Layer 3—IP Services Command Reference.
