radio helper-address

radio helper-address

To specify an IP address of a Dynamic Host Configuration Protocol (DHCP) server where User Datagram Protocol (UDP) broadcast packets are sent, use the radio helper-addressinterface configuration command. You can specify a DHCP server for UDP broadcast packets from subscriber units and a DHCP server for UDP broadcast packets from hosts. To disable the helper address for the subscriber units, use the no form of this command.

radio helper-address ip-addresssubscriber host

no radio helper-address ip-addresssubscriber host

Syntax Description		ip-address	IP address for the DHCP server.
		subscriber	Sets the downstream helper address to the DHCP server for UDP broadcast
			packets from the subscriber units.

		host	Sets the downstream helper address to the DHCP server for UDP broadcast
			packets from hosts.


Defaults		No default behavior or values.

12.1(3)XQ1	This command was introduced.

Examples	The first of the following examples sets the downstream helper address to the DHCP server at IP address
	10.x.x.x for UDP broadcast packets from the subscriber units, and the second example sets the
	downstream helper address to the DHCP server at IP address 172.56.x.x for UDP broadcast packets
	from hosts.
	UBR(config-if)#radio helper 10.x.x.x subscriber
