- 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 resending
neighbor solicitation messages every RetransTimer interval until
confirmation of reachability is received.
- ???? - Unknown state.
The following states are used for static entries:
- INCMP (Incomplete) -The interface for this entry is down.
- REACH (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.
Adding Static Neighbors (IPv6 Neighbor -- Add)
• IPv6 Address – The IPv6 address of a neighbor device that can be
reached through one of the network interfaces configured on this switch.
You can specify either a link-local or global unicast address formatted
according to RFC 2373 “IPv6 Addressing Architecture,” using 8
colon-separated 16-bit hexadecimal values. One double colon may be
used in the address to indicate the appropriate number of zeros required
to fill the undefined fields.
• VLAN – VLAN ID (Range: 1-4093)
• Hardware Address – The 48-bit MAC layer address for the neighbor
device. This address must be formatted as six hexadecimal pairs
separated by hyphens.
