Appendix A CSG2 Command Reference
ip csg radius reauthorization attribute
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-number | vsa {vendor-id | 3gpp}
radius-subattribute-number}
no ip csg radius reauthorization attribute {radius-attribute-number | vsa {vendor-id | 3gpp}
radius-subattribute-number}
Syntax Description
Defaults The default behavior is that no RADIUS attribute is defined.
Command Modes Global configuration
Command History
Usage Guidelines Roaming Service Control, also known as seamless roaming or RADIUS reauthorization, enables the
CSG2 to reauthorize prepaid users, instead of ending the users’ sessions, when a configured list of
attributes changes.
1. When you enable Roaming Service Control, you also configure a list of RADIUS attributes and VSA
subattributes to be monitored and saved by the CSG2.
2. When the CSG2 receives a RADIUS Start message, it saves the subset of attributes that are in both
the configured list and the message.
3. When the CSG2 receives a subsequent RADIUS Start or RADIUS Interim Accounting message, it
compares the saved subset of attributes to the list of attributes in the new message. (The CSG2
compares only the list of attributes, not the actual contents of those attributes.)
4. If any attribute in the saved subset is missing from the list of attributes in the new message, or if
there are any new attributes in the message that are not in the saved subset, the CSG2 reauthorizes
prepaid users without ending their sessions.
5. If service-level CDR summarization is enabled, the CSG2 sends a Service Usage CDR for each
service in the session.
