Parameters

vlan-interface interface-number: Specifies a VLAN interface number. If you do not specify this argument, the command displays information about all VLAN interfaces.

brief: Displays brief interface information. If you do not specify this keyword, the command displays detailed interface information.

description: Displays complete interface descriptions. If you do not specify this keyword, the command displays only the first 27 characters of each interface description.

down: Displays VLAN interfaces in down state and their down causes. If you do not specify this keyword, the command displays information about VLAN interfaces in all states.

Table 12: Command output

Field	Description
Vlan-interface2	VLAN interface name.
Current state	Physical link state of the VLAN interface: Administratively DOWN—The interface has been shut down by using the shutdown command. DOWN—The interface is administratively up, but its physical state is down. The VLAN of this VLAN interface does not contain any physical ports in up state. The ports might not be connected correctly or the links might have failed. UP—The interface is both administratively and physically up.
Line protocol state	Data link layer state of the VLAN interface: DOWN—The link layer protocol state of the interface is down. UP—The link layer protocol state of the interface is up.
Description	Description of the VLAN interface.
Bandwidth	Expected bandwidth of the VLAN interface.
Maximum transmission unit	MTU of the VLAN interface.
Internet protocol processing : Disabled	The VLAN interface is not assigned an IP address and cannot process IP packets.
Internet Address	IP address of the VLAN interface. The primary attribute indicates that the address is the primary IP address.
IP packet frame type	IPv4 packet framing format.
hardware address	MAC address of the VLAN interface.
IPv6 packet frame type	IPv6 packet framing format.
Output queue - Urgent queuing: Size/Length/Discards 0/100/0 Output queue - Protocol queuing: Size/Length/Discards 0/500/0 Output queue - FIFO queuing: Size/Length/Discards 0/75/0	Information about the urgent, protocol, and FIFO output queues: Size—Number of packets in the queue. Length—Maximum number of packets that the queue can contain. Discards—Number of dropped packets.
Last clearing of counters	The most recent time that the reset counters interface vlan-interface command was executed. This field displays Never if you have never executed this command.
Last 300 seconds input rate: 0 bytes/sec, 0 bits/sec, 0 packets/sec Last 300 seconds output rate: 0 bytes/sec, 0 bits/sec, 0 packets/sec	Average rates of input packets and output packets in the last 300 seconds (in Bps, bps, and pps).
Input: 0 packets, 0 bytes, 0 drops	Total number and size (in bytes) of the received packets of the interface and the number of the dropped packets.
Output: 0 packets, 0 bytes, 0 drops	Total number and size (in bytes) of the sent packets of the interface and the number of the dropped packets.
Brief information on interfaces in route mode	Brief information about Layer 3 interfaces.
Interface	Abbreviated interface name.
Link	Physical link state of the interface: UP—The interface is physically up. DOWN—The interface is physically down. ADM—The interface has been shut down by using the shutdown command. To restore the physical state of the interface, use the undo shutdown command. Stby—The interface is a backup interface in standby state. To see the primary interface, use the display interface-backup state command.
Protocol	Data link layer protocol state of the interface: UP—The data link layer protocol state of the interface is up. DOWN—The data link layer protocol state of the interface is down. UP(s)—The data link layer protocol of the interface is up, but the link is an on-demand link or does not exist. The (s) attribute represents the spoofing flag.
Primary IP	Primary IP address of the interface.
