Configuring Static ARP Addresses

For devices that do not respond to ARP requests, traffic will be dropped
because the IP address cannot be mapped to a physical address. If this
occurs, you can manually map an IP address to the corresponding physical
address in the ARP.
Command Usage
You can define up to 128 static entries in the ARP cache.
Static entries will not be aged out or deleted when power is reset. You
