State

The following states are used for dynamic entries:
I1 (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.
I2 (Invalid) - An invalidated mapping. Setting the state to invalid dis-associates the interface
identified with this entry from the indicated mapping (RFC 4293).
R (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.
S (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.
D (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.
P1 (Probe) - A reachability confirmation is actively sought by resending neighbor solicitation
messages every RetransTimer interval until confirmation of reachability is received.
U (Unknown) - Unknown state.
The following states are used for static entries:
I1 (Incomplete)-The interface for this entry is down.
R (Reachable) - The interface for this entry is up. Reachability detection is not applied to static
entries in the IPv6 neighbor discovery cache.
P2 (Permanent) - Indicates a static entry.
