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 Addr Physical layer MAC address.
State The following states are used for dynamic entries:
◆
INCMP (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.
◆
REACH (Reachable) - Positive confirmation was received within the
last ReachableTime interval that the forward path to the neighbor was
functioning. While in REACH 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 resending
neighbor solicitation messages every RetransTimer interval until
confirmation of reachability is received.
◆
UNKNO - Unknown state.
The following states are used for static entries:
◆
INCMP (Incomplete)-The interface for this entry is down.
◆
REACH (Reachable) - The interface for this entry is up. Reachability
detection is not applied to static entries in the IPv6 neighbor discovery
cache.
VLAN VLAN interface from which the address was reached.
