11.7.5 Viewing IPv6 Neighbor Table Information Page

Selection Criteria

IPv6 Interface Index - Selects the interface whose information has to be displayed.

Non-Configurable Data

Interface - Specifies the interface whose settings are displayed in the current table row.

IPv6 Address - Specifies the IPv6 address of neighbor or interface.

MAC Address - Specifies MAC address associated with an interface.

IsRtr - Specifies router flag.

Neighbor State - Specifies the state of the neighbor cache entry. Following are the states for

dynamic entries in the IPv6 neighbor discovery cache:

 Unknown - Address resolution is being performed on the entry. A neighbor solicitation

message has been sent to the solicited-node multicast address of the target, but the

corresponding neighbor advertisement message has not yet been received.

 Reach - 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.

Last Updated - Time since the address was confirmed to be reachable.

Command Buttons

Refresh - Refreshes the screen with most recent data.

Clear IPv6 Neighbors - Clear IPv6 neighbors on selected interface or all interfaces.
