Service Port IPv6 Neighbors
The Service Port IPv6 Neighbors page provides information about IPv6 neighbors the device has
discovered through the service port by using the Neighbor Discovery Protocol (NDP). The manually
configured static service port IPv6 neighbors are also displayed.

Table 15: Service Port IPv6 Neighbors Fields
Field
Description
IPv6 Addresses
Displays the IP address of the neighbor.
MAC Address
Displays the MAC address of the neighbor.
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 local.
•
Other – The neighbor entry is unknown.
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.
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:
