• To search by Interface, select Interface from the Search By list, enter the interface
ID in unit/slot/port format, for example, 2/1/1. Then click the Go button. If the address
exists, that entry is displayed.
7. To refresh the page with the latest information on the switch, click the Update button.
8. To clear the IPv6 neighbors on a selected interface or on all interfaces, click the Clear
button.
The following table describes the nonconfigurable data that is displayed.
Table 115. IPv6 Advanced Neighbor Table
Field Description
Interface The interface whose settings are displayed in the current table row.
IPv6 Address The IPv6 address of the 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 The state of the neighbor cache entry. Following are the states for
dynamic entries in the IPv6 neighbor discovery cache:
• Incmp. Address resolution is being performed on the entry.A neighbor
solicitation message was 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 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 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.
