show adjacency

To display adjacency table information, use the show adjacency command.

: show adjacency [{FastEthernet slot/port} | {GigabitEthernet slot/port} | {Null interface-number} | {Port-channel number} | {Vlan vlan_id} | detail | internal | summary]

Syntax Description

FastEthernet

(Optional) Specifies the Fast Ethernet interface.

slot/port

(Optional) Number of the slot and port.

GigabitEthernet

(Optional) Specifies the Gigabit Ethernet interface; valid values are from 1 to 9.

Null interface-number

(Optional) Specifies the null interface; the only valid value is 0.

Port-channel number

(Optional) Specifies the channel interface; valid values are from 1 to 64.

Vlan vlan_id

(Optional) Specifies the VLAN; valid values are from 1 to 4094.

detail

(Optional) Displays protocol detail and timer information.

internal

12.1(8a)EW

Support for this command was introduced on the Catalyst 4000 family switch.

12.1(12c)EW

Added support for extended VLAN addresses.

Usage Guidelines

Adjacency statistics are updated every 10 seconds.

The information contained in the show adjacency command includes the following:

Protocol interface
Type of routing protocol configured on the interface
Interface address
Method adjacency was learned
MAC address of the adjacent switch
Time left before the adjacency rolls out of the adjacency table; after it rolls out, a packet must use the same next hop to the destination
