ip csg radius proxy

ip csg radius proxy

To specify that the CSG2 is to be a proxy for RADIUS messages, use the ip csg radius proxy command in global configuration mode. To stop the CSG2 from proxying for RADIUS messages, use the no form of this command.

Syntax Description	vrf csg-vrf-name	(Optional) Virtual Routing and Forwarding (VRF) table which the CSG2 IP
		address is to use for RADIUS communication.
	csg-address	Specifies the CSG2 IP address.
		The CSG2 IP address must be a virtual IP address, and it must be unique (or
		the IP address-VRF name combination must be unique, if VRF is configured).
		The CSG2 IP address (or the IP address-VRF name combination) must not be
		specified in other CSG2 commands, and it must not match any real IP address,
		virtual IP address, or alias IP address (or IP address-VRF name combination)
		configured on the CSG2.
		If you want the CSG2 RADIUS proxy IP address to be a member of a CSG2
		interface subnet, you must configure the CSG2 IP address as follows:
		• In non-redundant configurations, you must configure the CSG2 IP address
		as a secondary IP address configured on the appropriate interface.
		• In redundant configurations, you must configure the CSG2 IP address as a
		standby secondary IP address on the appropriate interface.
		Note The CSG2 performs radius proxy processing only on User Datagram
		Protocol (UDP) traffic that is destined for the server IP address. The
		server IP address cannot be used for any other UDP communication
		with the CSG2.
	vrf server-vrf-name	(Optional) Virtual Routing and Forwarding (VRF) table which the server IP
		address is to use for RADIUS communication.
	server-address	Specifies the server IP address.
