View the neighbor cache

ND occurs when there is communication between IPv6 devices on a 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 neighbor cache retains data for a given neighbor until the entry times out. You can view and clear the contents of the neighbor cache using the commands described in this section. For more on this topic, see Neighbor Discovery (ND).
