show ipv6 neighbors The show ipv6 neighbors Privileged EXEC mode command displays IPv6 neighbor discovery cache information. Syntax • show ipv6 neighbors {static | dynamic}[ipv6-address ipv6-address] [mac-address mac-address] • static - Display static neighbor discovery cash entries. • dynamic - Display dynamic neighbor discovery cash entries. • ipv6-address - Display the neighbor discovery cache information entry of a specific IPv6 address. • mac-address - Display the neighbor discovery cache information entry of a specific MAC address. Command Mode Privileged EXEC mode. User Guidelines • The associated interface of a MAC address can be aged out from the FDB table, so 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. STALE - More than ReachableTime milliseconds have elapsed since the last positive confirmation was received that the forward path was functioning properly. While stale, no action takes place until a packet is sent. DELAY - More than ReachableTime milliseconds have elapsed since the last positive confirmation was received that the forward path was functioning properly, and a packet was sent within the last DELAY_FIRST_PROBE_TIME seconds. If no reachability confirmation is received within DELAY_FIRST_PROBE_TIME seconds of entering the DELAY state, a Neighbor Solicitation is sent and the state is changed to PROBE. PROBE - A reachability confirmation is actively sought by retransmitting Neighbor Solicitations every RetransTimer milliseconds until a reachability confirmation is received. IPv6 Addressing 229
