show lldp neighbor-info

Syntax

show lldp neighbor-info [<INTERFACE-NAME>] [vsx-peer]

Description

Displays information about neighboring devices for all interfaces or for a specific interface. The information displayed varies depending on the type of neighbor connected and the type of TLVs sent by the neighbor.

Command context

Manager (#)

Parameters

<INTERFACE-NAME>

Specifies the interface for which to show information for neighboring devices. Use the format member/slot/port (for example, 1/3/1).

[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.

Authority

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