Configuring RADIUS Accounting
The RADIUS accounting feature allows the AP to save accounting data on a RADIUS
accounting server, as described in RADIUS Accounting on page 2-23. Accounting is only
available on the R2, which must also be configured for authentication. To configure the R2
for accounting, have the following RADIUS accounting information available:
• Primary Accounting Server IP Address: IP Address of the primary RADIUS
accounting server. The IP Address must be an IP Version 4 address.
• Primary Accounting Server UDP Port: A value between 1 and 65535. Standard
values are 1813 (default) and 1645. This value must match the primary RADIUS
accounting server configuration. Each server must be assigned a different accounting
port number.
• Primary Accounting Server Retry Limit: Number of times to resend an accounting
packet if a RADIUS accounting server does not respond to a request. Valid range is 0
to 20 times. Default is 5.
• Primary Accounting Server Retry Timer: Number of seconds to wait for the server
to respond to a request before a retry. Valid range is 2 to 10 seconds. Default is 5
seconds.
• Secondary Accounting Server IP Address: IP Address of the secondary RADIUS
accounting server, if used. The IP Address must be an IP Version 4 address. If not using
a secondary RADIUS server (as a backup server), enter 0.0.0.0 or leave it blank.
• Secondary Accounting Server UDP Port: A value between 1 and 65535. Standard
values are 1813 (default) and 1645. This value must match the secondary RADIUS
server configuration.
• Secondary Accounting Server Retry Limit: Number of times to resend an
accounting packet if a RADIUS accounting server does not respond to a request. Valid
range is 0 to 20 times. Default is 5.
• Secondary Accounting Server Retry Timer: Number of seconds to wait for the
server to respond to a request before a retry. Valid range is 2 to 10 seconds. Default is
5 seconds.
• Shared Secret: The text string that ensures that the data exchanged between the server
and the AP is valid. The shared secret must match the corresponding entry for the AP
in the RADIUS accounting server database. Accounting has its own shared secret,
which is used for both the Primary and Secondary RADIUS accounting server.
• Interim Interval: Determines how often to send accounting updates from the R2 to
the server for this session. If set to zero, updates are not sent. This value can be
overridden by the RADIUS server.
