For information about using the SRC software with the RADIUS relay server to provide
accounting, see “RADIUS Relay Server and the SRC Software” on page 254.
Table 48 on page 254 shows the RADIUS attributes that must be included in accounting
requests. The attributes uniquely identify subscribers.
Table 48: Required RADIUS Accounting Attributes
Description For RADIUS Acct-Start and Acct-Stop Messages
Subscriber’s WAP Called-Station-id [30]
Subscriber’s MAC address Calling-Station-id [31]
For RADIUS Acct-On and Acct-Off Messages

Terminating the Wireless Subscriber’s Connection
The RADIUS relay server terminates the wireless subscriber’s session when one of
the following events occurs. When a subscriber session is terminated, the subscriber’s
IP address is released back into the available address pool.
■
The RADIUS relay server receives a RADIUS accounting stop request.
■
No RADIUS accounting messages are received for this subscriber for more than
24 hours.
RADIUS Relay Server and the SRC Software
The SRC software is an advanced subscriber configuration and management service.
The RADIUS relay server can optionally use the SRC software to perform addressing
and accounting services for the subscriber and WAP.
The RADIUS relay server uses the E Series router’s DHCP local server or DHCP external
server and SRC client process to communicate with the SRC software.
Using the SRC Software for Addressing
If you integrate the SAE software into the RADIUS relay server configuration, the
application can contribute to the address pool selection used to lease an address to
the subscriber. The SRC software only contributes to address pool selection when
the DHCP local server is used; it is not supported when a DHCP external server is
used.
Using the SRC Application for Accounting
If you use the SRC software with the RADIUS relay server feature, two accounting
domains might actually be created. The first domain is established by the WAP, when
