Address Resolution Protocol configuration
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 commands.
