ip-address - IP address to map to a specified hardware address.
hardware-address - Hardware address to map to a specified IP address. (The
format for this address is xx-xx-xx-xx-xx-xx.)
The ARP cache is used to map 32-bit IP addresses into 48-bit hardware (i.e.,

other routers on local network interfaces defined on this router.
The maximum number of static entries allowed in the ARP cache is 128.
