Use the CLEAR IP ARP_CACHE command to clear the Address Resolution 
Protocol table when ring configuration changes are made. The ARP table entries 
time out if not updated within 20 minutes.

You should clear the ARP table if you either:

■

Change a station's IP configuration (for example, interfaces, IP address)

■

Experience difficulty in communicating with a station

After the table is cleared, the DMM relearns all stations' IP-to-MAC addresses 
when the next IP-based operation is established. The ARP table is then rebuilt 
with the new information.

The following command clears the DMM ARP cache:

CB5000>  clear ip arp_cache

ARP Cache Flushed.

SET IP
SHOW IP
