•

ipv6-address—Shows the neighbor discovery cache information entry of a 
specific IPv6 address.

•

specific MAC address.

•

interface-id—Specifies an interface ID. The interface ID can be one of the

Command Mode

Privileged EXEC mode

User Guidelines

Since the associated interface of a MAC address can be aged out from the FDB 
table, the Interface field can be empty.

When an ARP entry is associated with an IP interface that is defined on a port or 
port-channel, the VLAN field is empty.

The possible neighbor cash states are:

•

INCMP (Incomplete)—Address resolution is being performed on the entry. 
Specifically, a Neighbor Solicitation has been sent to the solicited-node 
multicast address of the target, but the corresponding Neighbor 
Advertisement has not yet been received.

•

REACH (Reachable)—Positive confirmation was received within the last 
ReachableTime milliseconds that the forward path to the neighbor was 
functioning properly. While REACHABLE, no special action takes place as 
packets are sent.
