Description
Display the interface to which this neighbor is attached.
Display the MAC address of the neighbor.
Display the status for such neighbor.
INCOMPLETE - Address resolution is in progress and the
link-layer address of the neighbor has not yet been
determined.
REACHABLE - The neighbor is reachable recently (within
tens of seconds ago).
STALE-The neighbor is no longer to be reachable. Yet, until
traffic is sent to the neighbor, no attempt should be made to
verify its reachability.
DELAY - The neighbor is no longer to be reachable, and the
traffic has recently been sent to the neighbor.
Rather than probe the neighbor immediately, however, delay
sending probes for a short while in order to give upper layer
protocols a chance to provide reachability confirmation.
PROBE - The neighbor is no longer to be reachable, and
unicast Neighbor Solicitation probes are being sent to verify
reachability.
