Parameters

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.

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

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

Table 39: Command output

Field	Description
Vlan-interface2	VLAN interface name.
Current state	Physical state of a VLAN interface: DOWN (Administratively)—The administrative state of the VLAN interface is down, because it has been shut down by using the shutdown command. DOWN—The administrative state of the VLAN interface is 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 well connected correctly or the lines might have failed. UP—Both the administrative state and the physical state of the VLAN interface are up.
Line protocol state	Link layer protocol state of a VLAN interface: DOWN—The link layer protocol state of the VLAN interface is down. UP—The link layer protocol state of the VLAN interface is up.
Description	Partial or complete interface description configured by using the description command: If you do not specify the description keyword in the display interface brief command, this field displays only the first 27 characters of the interface description. If you specify the description keyword in the display interface brief command, this field displays the complete interface description.
Bandwidth	Expected bandwidth of a VLAN interface.
Maximum transmission unit	MTU of a VLAN interface.
Internet protocol processing : Disabled	The interface cannot process IP packets. This information is displayed when the interface is not configured with an IP address.
Internet address : 192.168.1.54/24 (primary)	The primary IP address of the interface is 192.168.1.54/24. This information is displayed only when the primary IP address is configured for the interface.
IP packet frame type	Framing format of sent IPv4 packets.
hardware address	MAC address of the VLAN interface.
IPv6 packet frame type	Framing format of sent IPv6 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 not executed this command since the device startup.
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.
Link: ADM - administratively down; Stby – standby	Link layer state of the interface: ADM—The interface has been administratively shut down. To bring up the interface, use the undo shutdown command. Stby—The interface is operating as a backup interface.
Protocol: (s) - spoofing	The protocol attribute of an interface includes the spoofing flag (the letter s in parentheses) when the following conditions exist: The data link layer protocol state of an interface is shown as UP. Its link is an on-demand link or is not present.
Interface	Abbreviated interface name.
Link	Physical link state of the interface: UP—The physical link of the interface is up. DOWN—The physical link of the interface is down. ADM—The interface has been administratively shut down. To bring up the interface, use the undo shutdown command. Stby—The interface is operating as a backup interface.
Protocol	Data link layer state of the interface: UP—The data link layer of the interface is up. DOWN—The data link layer of the interface is down. UP(s)—The data link layer of the interface is spoofing up. This state is available for on-demand link setup applications. This state enables the device to initiate an on-demand link setup when a link is not present.
Primary IP	Primary IP address of the interface.
