GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches 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 IPv6 Address MAC Address IsRtr Neighbor State Last Updated. Description Specifies the IPv6 address of neighbor or interface. Specifies MAC address associated with an interface. 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. 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. Time since the address was confirmed to be reachable. 39
