Viewing the neighbor cache
Neighbor discovery occurs when there is communication between the switch and another, reachable IPv6 device on the same VLAN. A neighbor destination is reachable from a given source address if a confirmation (neighbor solicitation) has been received at the source verifying that traffic has been received at the destination.
The switch maintains an IPv6 neighbor cache that is populated as a result of communication with other devices on the same VLAN.
You can view the contents of the neighbor cache using the commands described in this section.
