show adjacency
Usage Guidelines The show adjacency command is used to verify that an adjacency exists for a connected device, that the
adjacency is valid, and that the MAC header rewrite string is correct.
For line cards, you must specify the line card if_number (interface number). Use the show cef interface
command to obtain line card if_numbers.
You can use any combination of the ip-address, interface-type, and other keywords and arguments (in
any order) as a filter to display a specific subset of adjacencies.
The following information may be displayed by the show adjacency commands:
• Protocol
• Interface
• Type of routing protocol that is configured on the interface
• Type of routed protocol traffic using this adjacency
• Next hop address
• Method of adjacency that was learned
• Adjacency source (for example, Address Resolution Protocol (ARP) or ATM Map)
• Encapsulation prepended to packet switched through this adjacency
• Chain of output chain elements applied to packets after an adjacency
• Packet and byte counts
• High availability (HA) epoch and summary event epoch
• MAC address of the adjacent router
• Time left before the adjacency rolls out of the adjacency table. After the adjacency rolls out, a packet
must use the same next hop to the destination.
Examples The following example shows how to display a summary of adjacency information:
Router# show adjacency summary
Adjacency table has 7 adjacencies:
each adjacency consumes 368 bytes (4 bytes platform extension)
6 complete adjacencies
