ARP Commands

Use the ip proxy-arp command in Interface Configuration mode to enable 

proxy ARP on a router interface. Without proxy ARP, a device only responds 

to an ARP request if the target IP address is an address configured on the 

interface where the ARP request arrived. With proxy ARP, the device may also 

respond if the target IP address is reachable. The device only responds if all 

next hops in its route to the destination are through interfaces other than the 

interface that received the ARP request. Use the no form of the command to 

disable proxy ARP on a router interface.

Enabled is the default configuration.

Interface Configuration (VLAN) mode

This command has no user guidelines.

The following example enables proxy arp for VLAN 15.

(config)#interface vlan 15

console(config-if-vlan15)#ip proxy-arp

Use the show arp command in Privileged EXEC mode to display the Address 

Resolution Protocol (ARP) cache entries statically added or dynamically 

learned on the routing ports. The displayed results are not the total ARP 

entries. To view the total ARP entries, the operator should view the show ARP 

results in conjunction with the show ARP switch results.
