Table 32: ShowIPv6 Neighbors - display description

Field

Description

IPv6 Address

IPv6 address of neighbor.

Age

The time since the address was verified as reachable (in seconds). A static

entry is indicated by the value “Permanent.”

Link-layer

Address

Physical layer MAC address.

State

The following states are used for dynamic entries:

Incomplete - Address resolution is being carried out on the entry.

A neighbor solicitation message has been sent to the multicast

address of the target, but it has not yet returned a neighbor

advertisement message.

Invalid - An invalidated mapping. Setting the state to invalid dis-

associates the interface identified with this entry from the indicated

mapping (RFC 4293).

Reachable - Positive confirmation was received within the last

ReachableTime interval that the forward path to the neighbor was

functioning. While in Reachable state, the device takes no special

action when sending packets.

Stale - More than the ReachableTime interval has elapsed since the

last positive confirmation was received that the forward path was

functioning. While in Stale state, the device takes no action until a

packet is sent.

Delay - More than the ReachableTime interval has elapsed since the

last positive confirmation was received that the forward path was

functioning. A packet was sent within the last

DELAY_FIRST_PROBE_TIME interval. If no reachability confirmation is

received within this interval after entering the Delay state, the switch

will send a neighbor solicitation message and change the state to

Probe.

Probe - A reachability confirmation is actively sought by re-sending

neighbor solicitation messages every RetransTimer interval until

confirmation of reachability is received.

Unknown - Unknown state.

The following states are used for static entries:

Incomplete - The interface for this entry is down.

Permanent - Indicates a static entry.

Reachable - The interface for this entry is up. Reachability detection is

not applied to static entries in the IPv6 neighbor discovery cache.

VLAN

VLAN interface from which the address was reached.
