Adjacency table configuration commands 1

display adjacent-table· 1

display ipv6 adjacent-table· 3

 

The adjacency table feature only applies to hardware forwarding, but not software forwarding.

The adjacency table feature does not apply to Ethernet networks that use ARP for storing and managing neighbor information.

You can only view adjacency tables of tunnel interfaces. For more information about tunnel interfaces, see Layer 3—IP Services Configuration Guide.
