RADIUS Accounting
RADIUS Accounting
RADIUS accounting tracks users’ activity and consumption of network
resources. NASs, such as the Wireless Edge Services zl Module, send reports
that summarize users’ activity to a centralized RADIUS accounting server. A
company might analyze the reports for security auditing and traffic manage-
ment. Or the company might submit the reports to a billing server in order to
charge users for wireless access.
The Wireless Edge Services zl Module can implement RADIUS accounting in
one of two ways:
■ It can report to an external RADIUS server.
■ It can report to its internal RADIUS server.
The module can send the following messages:
■ Stop messages—when a station disconnects from a wireless LAN
(WLAN)
■ Start messages—when a station connects to a WLAN
■ Interim messages—at set intervals throughout the station’s session
You choose which messages the module sends.
A message includes information such as the identity of the user, the duration
of the session, and the bandwidth consumed. Table 11-4 shows a complete list
of fields in the report. Some fields are present in all messages; others are
specific to certain types of messages.
