Table 19: Network Port IPv6 Neighbors Fields
Field Description
IPv6 Address Displays the IP address of the neighbor.
MAC Address Displays the MAC address of the neighbor.
IS Router 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.
Type The type of the neighbor entry, which is one of the following:
•
Static – The neighbor entry is manually configured.
•
Dynamic – The neighbor entry is dynamically resolved.
•
Local – The neighbor entry is a local entry.
•
Other – The neighbor entry is an unknown entry.
Neighbor State Specifies the state of the neighbor cache entry. 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 reachability status cannot be determined.
Last Updated Displays the time since the address was confirmed to be reachable.
Use the buttons to perform the following tasks:
•
To add network port static IPv6 neighbor entry, click Add and configure the desired settings.
•
To remove network port static IPv6 neighbor entries, select each static neighbor entry to remove
and click
Remove .
After you click Add or Edit , a window opens and allows you to configure Network Port IPv6 Neighbor
settings.
You can configure the IPv6 Address and the MAC Address.
