13 ARP Commands
13.1 arp
To add a permanent entry in the Address Resolution Protocol (ARP) cache, use the arp command in 
global configuration mode. To remove an entry from the ARP cache, use the no form of this command. 
 
Command Syntax 
arp [vrf vrf-name] ip-address hardware-address 
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 
No entries are permanently installed in the ARP cache.
 
Command Mode 
Global configuration
 
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

13.2 arp timeout
To configure how long a dynamically learned IP address and its corresponding Media Control Access 
(MAC) address remain in the Address Resolution Protocol (ARP) cache, use the arp timeout 
command in interface configuration mode. To restore the default value, use the no form of this 
command.
