Table 32: Show IPv6 Neighbors - display description
Field Description
IPv6 Address IPv6 address of neighbor.
Age The time since the address was verified as reachable (in seconds). A static entry is
indicated by the value “Permanent.”
Link-layer
Address Physical layer MAC address.
State The following states are used for dynamic entries:
◆
Incomplete - Address resolution is being carried out on the entry.
A neighbor solicitation message has been sent to the multicast address of
the target, but it has not yet returned a neighbor advertisement message.
◆
Invalid - An invalidated mapping. Setting the state to invalid dis-associates
the interface identified with this entry from the indicated mapping (RFC
4293).
◆
Reachable - Positive confirmation was received within the last
ReachableTime interval that the forward path to the neighbor was
functioning. While in Reachable state, the device takes no special action
when sending packets.
◆
Stale - More than the ReachableTime interval has elapsed since the last
positive confirmation was received that the forward path was functioning.
While in Stale state, the device takes no action until a packet is sent.
◆
Delay - More than the ReachableTime interval has elapsed since the last
positive confirmation was received that the forward path was functioning. A
packet was sent within the last DELAY_FIRST_PROBE_TIME interval. If no
reachability confirmation is received within this interval after entering the
Delay state, the switch will send a neighbor solicitation message and
change the state to Probe.
◆
Probe - A reachability confirmation is actively sought by re-sending
neighbor solicitation messages every RetransTimer interval until
confirmation of reachability is received.
◆
Unknown - Unknown state.
