13.1 arp
To add a permanent entry in the Address Resolution Protocol (ARP) cache, use the arp command in

Command Syntax

no arp [vrf vrf-name] ip-address
ip-address IP address in four-part dotted decimal format corresponding to the local
data-link address.
vrf vrf-name Virtual Routing and Forwarding (VRF) instance. The vrf-name argument is
the name of the VRF table.
hardware-address Local data-link address (a 48-bit address).
Default

Usage
Because most hosts support dynamic resolution, you generally need not specify static ARP cache
entries.
To remove all nonstatic entries from the ARP cache, use the clear arp-cache privileged EXEC
command.
Examples
The following is an example of a static ARP entry for a typical Ethernet host:
Switch(config)# arp 10.31.7.19 0800.0900.1834

in interface configuration mode. To restore the default value, use the no form of this command.
