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-option interface 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.

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
