Configuring the ARP Timeout

You can set the ARP timeout, which is the timeout in seconds, for dynamic
ARP cache entries associated with an interface. When the timeout value is
exceeded, the Cuda 12000 flushes out-of-date cache entries from the ARP
cache. The cache contains IP addresses and their associated MAC addresses
that were stored in response to an ARP reply.

Valid ARP timeout values range from 0 to 604800 seconds. The default is
600 seconds. A value of 0 means that ARP entries will never timeout.

To configure the ARP timeout for an interface, perform the following tasks:

Note that you can set the ARP timeout to 0 using the no arp timeout
command.

Example

cli:192.168.208.3:interface:cable:csi(1/1/1)# interface 1/11/1

mode:

interface:ethernet:csi(1/11/1)cli:192.168.208.3:interface:ethernet:csi(1/11/

2)# arp timeout 700

cli:192.168.208.3:interface:ethernet:csi(1/11/2)# show arp timeout
