Enables Proxy Address Resolution Protocol (APR) on an interface.
Proxy ARP is disabled.
Interface subtype configuration mode
Proxy ARP enables a device to answer ARP requests from devices in one network on behalf of devices in another network. Because ARP requests are MAC-layer broadcasts, they reach only the devices that are directly connected to the sender of the ARP request. Therefore, ARP requests do not cross routers.
The no form of the command disables Proxy ARP on an interface.
The following example enables Proxy ARP on a specified interface.
device(config)# interface ethernet 3/4 device(conf-if-eth-3/4)# ip proxy-arp
The following example disables Proxy ARP on a specified interface.
device(config)# interface ethernet 3/4 device(conf-if-eth-3/4)# no ip proxy-arp
