Arp timeout <>
sets the ARP (Address Resolution Protocol) cache
timeout. The timeout defines the period an ARP
entry remains in the cache. When a new timeout
value is assigned, it only affects the new ARP
entries. All the older entries retain their old
timeout values. The timeout values can be
assigned to dynamic ARP entries only. static ARP
entries remain unaltered by timeout value.
timeout <seconds (30-86400)>
default: 7200
