show udld

描述

Displays UDLD information for all interfaces or for a specific interface.

Command context

Operator (>)或经理(#)

Parameters

interface

Specifies the name of a logical interface on the switch, which can be:

• An Ethernet interface associated with a physical port. Use the format会员/槽/ port(for example,1/3/1).

• UDLD runs only on physical interfaces. LAGs, tunnels, and the like are not supported. However, UDLD can be configured individually on each port of a LAG or trunk group. Configuring UDLD on a trunk group primary port enables UDLD on that port only.

[vsx-peer]

Shows the output from the VSX peer switch. If the switches do not have the VSX configuration or the ISL is down, the output from the VSX peer switch is not displayed. This parameter is available on switches that support VSX.

权威

Operators or Administrators or local user group members with execution rights for this command. Operators can execute this command from the operator context (>) only.

Examples

On the 6400 Switch Series, interface identification differs.
