the requestor, who stores the sender information in its ARP cache. Newer information
always replaces existing content in the ARP cache.
The number of supported ARP entries is platform-dependent.
Devices can be moved in a network, which means the IP address that was at one
time associated with a certain MAC address is now found using a different MAC, or
may have disappeared from the network altogether (i.e., it has been reconfigured,
disconnected, or powered off). This leads to stale information in the ARP cache
unless entries are updated in reaction to new information seen on the network, peri-
odically refreshed to determine if an address still exists, or removed from the cache if
the entry has not been identified as a sender of an ARP packet during the course of
an ageout interval, usually specified via configuration.

.
MAC Address
The unicast MAC address (hardware address) associated with the net-
work host. When adding a static ARP entry, specify the MAC address
to associate with the IP address in the entry.
Interface
The routing interface associated with the ARP entry. The network host
is associated with the device through this interface.
Type
The ARP entry type:
Dynamic: An ARP entry that has been learned by the router
Gateway: A dynamic ARP entry that has the IP address of a rout-
ing interface
Local: An ARP entry associated with the MAC address of a rout-
ing interface on the device
Static: An ARP entry configured by the user
Age
The age of the entry since it was last learned or refreshed. This value
is specified for Dynamic or Gateway entries only (it is left blank for all
