Cisco Cisco IOS Software Release 12.2(13)ZF

Timer issue when the arp timeout is set to 60 min from the default 4 hr.

Configuring authorized arp allows dynamic ARP entries to be installed.

Timer expired notification is sent by ARP to DHCP when no arp auth is enabled.

Configuring arp auth removes the ARP entry if the age exceeds the ARP timeout.
