Each dynamic ARP entry in theARP table has a limited lifetime rather than is always valid. Dynamic ARP entries that are not refreshedbefore expiring are deleted from the ARP table. The lifetime is called the aging time. The aging time isreset each time the dynamic ARP entry is used within the lifetime. You can adjust the aging time fordynamic ARP entries according to the actual network condition.Follow these steps to set the aging time for dynamic ARP entries:To do… Use the command… RemarksEnter system view system-view —Set the aging time for dynamicARP entries arp timer aging aging-time Optional20 minutes by default.
