ip csg radius reauthorization attribute

To define the RADIUS attributes and VSA subattributes to be monitored by the CSG2, and to enable Roaming Service Control, use the ip csg radius reauthorization attribute command in global configuration mode. To delete a RADIUS attribute, use the no form of this command.

ip csg radius reauthorization attribute {radius-attribute-numbervsa {vendor-id3gpp}

radius-subattribute-number}

no ip csg radius reauthorization attribute {radius-attribute-numbervsa {vendor-id3gpp} radius-subattribute-number}

Syntax Description	radius-attribute-number		Specifies the RADIUS attribute number. The range is from 1 to 255.
	vsa		Specifies the vendor-specific attribute (VSA).
	vendor-id		Specifies the vendor ID number. The range is from 1 to 16777215.
	3gpp		Specifies the Third Generation Partnership Project (3GPP) vendor ID.

Command History	Release	Modification

Usage Guidelines	Roaming Service Control, also known as seamless roaming or RADIUS reauthorization, enables the
	CSG2 to reauthorize prepaid users when specified RADIUS attributes change, rather than ending the
	users’ sessions.

When a RADIUS Start request is received, the specified attributes are saved. When a subsequent Start or Intermediate Accounting message is received, the specified attributes in the new message are compared with the saved attributes. If any attribute is different, each service is reauthorized, as new traffic for the service arrives.

If both Roaming Service Control and the reporting of RADIUS attributes are enabled, the CSG2 monitors both sets of attributes, but only changes in the Roaming Service Control attributes trigger reauthorization. For more information about the reporting of RADIUS attributes, see the “Reporting RADIUS Attributes and VSA Subattributes” section on page 9-7.
