This command removes entries from the Address Resolution Protocol (ARP) cache. Normally, dynamic entries are timed out after 20 minutes and static entries remain in the cache until the device is restarted.
This command is useful when new hardware using the same higher level protocol address is replaced on a network. It is necessary since the previous hardware address is retained in the ARP mapping cache.
reset arp {address | all}
address | This is the high-level address associated with the hardware address in the ARP cache to be deleted. It must be either a legal IP address specified in dotted- decimal format or an AppleTalk address specified as net:node. |
all | This option specifies that all entries, dynamic and static, be deleted from the ARP cache. |
