display interface

Use display interface to display information about an S-channel interface, an S-channel aggregate interface, a VSI interface, or a VSI aggregate interface.

Syntax

display interface [ s-channel | schannel-aggregation ] [ brief [ down ] ]

display interface [ { s-channel | schannel-aggregation } [ interface-number:channel-id | interface-number:channel-id.vsi-local-id ] ] [ brief [ description ] ]

Parameters

s-channel: Specifies an S-channel interface or a VSI interface.

schannel-aggregation: Specifies an S-channel aggregate interface or a VSI aggregate interface.

interface-number:channel-id: Specifies an S-channel interface or S-channel aggregate interface. The interface-number argument specifies the interface where the S-channel resides. The channel-id argument specifies the ID of the S-channel.

interface-number:channel-id.vsi-local-id: Specifies a VSI interface or VSI aggregate interface. The interface-number argument specifies the interface where the S-channel resides. The channel-id argument specifies the ID of the S-channel. The vsi-local-id argument specifies the local ID of the VSI.

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

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

description: Displays a complete interface description in brief information when you configure an interface description string longer than 27 characters. If you do not specify this keyword, the command displays only the first 27 characters in brief information.

Usage guidelines

If you do not specify the s-channel keyword, the command displays information about all interfaces.

If you specify the s-channel keyword but do not specify an S-channel interface or VSI interface, the command displays information about all created S-channel interfaces and VSI interfaces.

Table 6: Command output

Field	Description
Current state	Interface status: Administratively DOWN—The interface is administratively down. DOWN—The interface is administratively up but physically down. UP—The interface is both administratively and physically up.
Hardware Address	Hardware address of the interface.
Description	Description information for the interface.
Bandwidth	Expected bandwidth for an S-channel interface or a VSI interface.
PVID	Default VLAN ID of the interface.
Port link-type	Link type of the interface.
Trunk port encapsulation	Encapsulation type of the trunk port.
Last clearing of counters	Last time the reset counters interface command was executed to clear interface statistics. Never indicates interface statistics have never been cleared since startup.
Input (total): 6 packets, 384 bytes	Total number of packets and bytes that the S-channel interface received.
Output (total): 18 packets, 1152 bytes	Total number of packets and bytes that the S-channel interface sent.
Link	Physical connection status of an interface: UP—The interface is physically up. DOWN—The interface is physically down. ADM—The interface was shut down by using the shutdown command. Bring it up by using the undo shutdown command. Stby—A standby interface.
Duplex	Duplex mode of an interface: (a)/A—Autonegotiation. H—Half-duplex. F—Full-duplex.
Cause	Causes of a DOWN link: Administratively—The interface was shut down by executing the shutdown command. To restore the physical state of the interface, use the undo shutdown command. Not connected—No physical connection because of absence or failure of network cables.
