Appendix C. RADIUS Accounting

This section will briefly introduce the basic configuration of RADIUS server to work with VSA for controlling the
maximum client volume usage (upload; download or upload + download traffic).
This VSA will be sent from the RADIUS server to the gateway along with an Access-Accept packet. In other
words, when the external RADIUS server accepts the request, it will reply not only an Access-Accept but
also a maximum value in bytes each user is allowed to transfer. This value can be the maximum upload traffic,
the maximum download traffic, or the sum of the download and upload traffics in bytes per user. The gateway
will check this value every minute; if the user traffic reaches this value, the gateway will stop the session of
this user and send a "Stop" to RADIUS server.
1. Description
VSA is designed to allow vendors to support their own extended Attributes which are not covered in common
attributes. It MUST not affect the operation of the RADIUS protocol.
The Attribute Type of VSA is "26" and the "Vendor ID" should be determined before proceeding to RADIUS
configuration; in this example; the Vendor ID is "21920". "Attribute Number" and "Attribute Value" can then
be designed to provide additional control over RADIUS.
