Address Resolution Protocol (ARP) is the TCP/IP protocol that resides within the Internet layer. ARP resolves a physical
address from an IP address. ARP queries machines on the local network for their physical addresses. ARP also
maintains IP to physical address pairs in its cache memory. In any IP communication, the ARP cache is consulted to
see if the IP address of the computer or the router is present in the ARP cache. Then the corresponding physical
address is used to send a packet.
The following table describes the ARP Configuration Menu options.

ARP Static configuration
Command: /cfg/l3/arp/static
[Static ARP Menu]
add - Add a permanent ARP entry
del - Delete an ARP entry
cur - Display current static ARP configuration
Static ARP entries are permanent in the ARP cache and do not age out like the ARP entries that are learnt
dynamically. Static ARP entries enable the switch to reach the hosts without sending an ARP broadcast request to the
network. Static ARPs are also useful to communicate with devices that do not respond to ARP requests. Static ARPs
can also be configured on some gateways as a protection against malicious ARP Cache corruption and possible DOS
attacks.
