Table 48 on page 244 shows the RADIUS attributes that must be included in accounting
requests. The attributes uniquely identify subscribers.

Table 48: Required RADIUS Accounting Attributes

For RADIUS Acct-Start and Acct-Stop Messages
Called-Station-id [30]
Calling-Station-id [31]
For RADIUS Acct-On and Acct-Off Messages

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.
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.
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.
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 the subscriber
is authenticated. The second domain is created for the connection between the E Series
router and the SRC software.
If you want to continue to use the SRC software's user session and problem-tracking
features, you should not configure the SRC software to generate RADIUS accounting
