Command Line Interface Reference for the ProSafe 7300S Series Layer-3 Stackable Switches, 14.1.8.1 no arp timeout This command configures the default ARP entry ageout time. Format no arp timeout Mode Global Config 14.1.9 clear arp-cache This command causes all ARP entries of type dynamic to be removed from the ARP cache. If the gateway parameter is specified, the dynamic entries of type gateway are purged as well. Format clear arp-cache [gateway] Mode Privileged EXEC 14.1.10 show arp This command displays the ARP cache. The displayed results are not the total ARP entries. To view the total ARP entries, combine the show arp results and the show arp switch results. Format show arp Mode Privileged EXEC Age Time (seconds) Is the time it takes for an ARP entry to age out. This value was configured into the unit. Age time is measured in seconds. Response Time (seconds) Is the time it takes for an ARP request timeout. This value was configured into the unit. Response time is measured in seconds. Retries Is the maximum number of times an ARP request is retried. This value was configured into the unit. Cache Size Is the maximum number of entries in the ARP table. This value was configured into the unit. Dynamic Renew Mode Displays whether the ARP component automatically attempts to renew dynamic ARP entries when they age out. Routing Commands v3.0, January 2008 14-5
