User Guidelines

The associated interface of a MAC address can be aged out from the FDB table, so that the Interface field

can be empty.

When an ARP entry is associated with an IP interface that is defined on a port or port-channel, the VLAN field

is empty.

The possible neighbor cache states are:

INCMP (Incomplete) — Address resolution is being performed on the entry. Specifically, a Neighbor

Solicitation has been sent to the solicited-node multicast address of the target, but the corresponding
Neighbor Advertisement has not yet been received.

REACH (Reachable) — Positive confirmation was received within the last ReachableTime milliseconds

that the forward path to the neighbor was functioning properly. While REACHABLE, no special action
takes place 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 STALE, no action takes place 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, and a packet was sent within the last
