Command History

To configure the Cisco uBR7200 series so that it inserts the subscriber unit MAC-address into a DHCP packet when a packet is received from a subscriber unit or another host, use the radio relay-agent-optioninterface configuration command. The Cisco uBR7200 series then forwards the packet to a DHCP server. To disable the insertion, use the no form of this command.

12.1(3)XQ1	This command was introduced.

Usage Guidelines If you are having trouble, make sure that you entered the correct port and subscriber unit card slot number when you activate radio relay-agent-option. A DOCSIS-compliant DHCP server is required. The DHCP server verifies that the fixed IP address, if any, returned to the host is valid for the IP subnet on that downstream interface. The IP address must be unique and valid in the subnet for the user to obtain connectivity.

Examples	The following example enables the insertion of DHCP relay-agent information into DHCP packets:
	Router(config-if)#radio relay-agent-option
