Command History

To activate the radio proxy Address Resolution Protocol (ARP) for host-to-host communications, use the radio proxy-arpinterface configuration command. The radio proxy ARP enables the Cisco uBR7200 series to issue ARP requests on behalf of the subscriber units on the same wireless network subnet. To disable this feature, use the no form of this command.

12.1(3)XQ1	This command was introduced.

Usage Guidelines To verify if radio proxy ARP has been activated or deactivated, enter the show running-configcommand and look for the interface configuration information. If radio proxy ARP has been activated, it does not appear in this output. If radio proxy ARP has been deactivated, it appears in the output as no radio proxy-arp. If you are having trouble, make sure that you entered the correct port and radio modem card slot number when you activated radio proxy ARP.

Examples	The following example shows how to activate proxy ARP for host-to-host communications:
	CMTS01(config-if)# radio proxy-arp
