Avaya M770 ATM Switch User’s Guide

Managing the IP Cache

This section explains how to view the IP and route ARP cache of the M770 ATM 
Switch and how to delete entries in the ARP cache.

When listing the contents of the M770 ATM Switch’s IP ARP cache, the destination 
IP and MAC addresses are shown. Also displayed is whether or not the ARP 
process has completed for each destination IP address in the IP ARP cache.
An entry in the cache becomes aged out 30 minutes from the last time it was used.
To display the contents of the M770 ATM Switch’s IP ARP cache, use the

ip arpcache show

 

command.

When you delete an entry from a M770 ATM Switch IP ARP cache that still has IP 
traffic on it, there will be a short delay while the ARP process finds the remote host 
and the IP address is added to the ARP cache again.

If an IP address is moved on the network then you should delete the entry in 

the IP ARP cache to force the M770 ATM Switch to locate the new MAC address.

To delete an entry from the M770 ATM Switch’s IP ARP cache, use the

ip 

arpcache delete

 

command.

Command:

M15-155s8:/>ip arpcache show

Output:
