Release 5.1 Supplement for Remote Annexes
Accounting
This section describes the RADIUS Accounting features that the Remote
Annex supports. Note that the RADIUS Accounting-Request {4}
packets include the actual values of RADIUS attributes used, and not
necessarily the values returned in the Access-Accept {2} packet. For
example, this means that for a PPP user, the Framed-IP-Address (8)
attribute is the address actually negotiated during IPCP startup, and not
necessarily the address returned by RADIUS. Note that this address is
included in the Accounting-Request {4} packet when Acct-Status-Type
(40) = IPCP-Start [VSE Bay Networks 3], because the actual negotiated
address is not known at authentication time.
Events
This section describes the events that trigger RADIUS Accounting from
the Remote Annex. Each RADIUS Accounting log is queued for
transmission, and once transmitted, requeued for acknowledgment. When
the Remote Annex receives the corresponding Accounting-Response, the
Accounting-Request log is purged. Periodically, the Remote Annex
retransmits the Accounting-Request logs that have been sitting on the
acknowledgment queue. Once the Remote Annex determines that it has
too many logs, the Remote Annex starts syslogging the oldest ones and
purging them from memory, clearing room for newer events to be held
in buffers.
