This command deletes all dynamic entries in the IPv6 neighbor discovery cache.
Command Mode
Privileged Exec
Example
The following deletes all dynamic entries in the IPv6 neighbor cache:
State The following states are used for dynamic entries:
• INCMP (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.
• REACH (Reachable) - Positive confirmation was received within the last
ReachableTime interval that the forward path to the neighbor was functioning.
While in REACH 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 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.
