3Com CoreBuilder 2500 - Removing an ARP Cache Entry; Flushing the ARP Cache

10-12 CHAPTER 10: ADMINISTERING IP ROUTING
Removing an ARP
Cache Entry
You can remove an entry from the ARP cache if the MAC address has
changed.
To remove an entry from the ARP cache:
1 From the top level of the Administration Console, enter:
ip arp remove
2 Enter the IP address that you want to remove.
The address is immediately removed from the table. If necessary, the
system subsequently uses ARP to find the new MAC address
corresponding to that IP address.
Flushing the ARP
Cache
You can delete all entries from the ARP cache if the MAC address has
changed.
To remove all entries from the ARP cache, from the top level of the
Administration Console, enter:
ip arp flush
All ARP cache entries are immediately removed from the table.
