Click Clear to delete all entries from the table. The table is repopulated as the IPv6 neighbors
are discovered on the network. Click Refresh to refresh the screen with most recent data.
The following table describes the information the IPv6 Network Interface Neighbor Table
displays
Field Description
IPv6 Address Specifies the IPv6 address of neighbor or interface.
MAC Address Specifies MAC address associated with an interface.
IsRtr Indicates whether the neighbor is a router. If the neighbor is a router, the value is
True. If the neighbor is not a router, the value is False.
Neighbor State Specifies the state of the neighbor cache entry. The following are the states for
dynamic entries in the IPv6 neighbor discovery cache:
• Reachable. Positive confirmation was received within the last Reachable Time
milliseconds that the forward path to the neighbor was functioning properly. While
in REACH state, the device takes no special action 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 in
STALE state, the device takes no action 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. 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, 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 milliseconds until a reachability
confirmation is received.
• Unknown. The switch cannot determine the state of the cache entry.
Last Updated. Time since the address was confirmed to be reachable.
