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. Table 122 ARP Configuration commands

Command	Description
ip arp rearp <2-120>	Defines re-ARP period in minutes. You can set this duration between 2
	and 120 minutes.
show ip arp	Displays the current ARP configurations.
	Command mode: All except User EXEC
