ip csg radius reauthorization attribute {radius-attribute-number | vsa {vendor-id | 3gpp}

radius-subattribute-number}

Command History

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.

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.
