IPv6 Management and Interfaces

391

Cisco 500 Series Managed Switch Administration Guide

This page displays the neighbors that were automatically detected or manually 
configured entries. Each entry displays to which interface the neighbor is 
connected, the neighbor’s IPv6 and MAC addresses, the entry type (static or 
dynamic), and the state of the neighbor.

To define IPv6 neighbors: 

In Layer 2 system mode, click Administration > Management Interface > IPv6 
Neighbors.
In Layer 3 system mode, click IP Configuration > IPv6 Management and 
Interfaces > IPv6 Neighbors.

You can select a Clear Table option to clear some or all of IPv6 addresses in the 
IPv6 Neighbors Table. 

•

Static Only—Deletes the static IPv6 address entries. 

•

Dynamic Only—Deletes the dynamic IPv6 address entries. 

•

All Dynamic & Static—Deletes the static and dynamic address entries IPv6 
address entries. 

The following fields are displayed for the neighboring interfaces:

•

Interface—Neighboring IPv6 interface type.

•

IPv6 Address—IPv6 address of a neighbor.

•

MAC Address—MAC address mapped to the specified IPv6 address.

•

Type—Neighbor discovery cache information entry type (static or dynamic).

•

State—Specifies the IPv6 neighbor status. The values are:

-

Incomplete

—Address resolution is working. The neighbor has not yet 

responded. 

-

Reachable

—Neighbor is known to be reachable.

-

Stale

—Previously-known neighbor is unreachable. No action is taken to 

verify its reachability until traffic must be sent.

-

Delay

—Previously-known neighbor is unreachable. The interface is in 

Delay state for a predefined Delay Time. If no reachability confirmation is 
received, the state changes to Probe.

-

Probe

—Neighbor is no longer known to be reachable, and Unicast 

Neighbor Solicitation probes are being sent to verify the reachability.
