RADIUS Accounting Records

RADIUS Accounting Records

SSG sends accounting records with the associated attributes to the RADIUS accounting server when the following events occur:

•Account Login and Logout, page 4-2

•Service Connection and Termination, page 4-3

Account Login and Logout

SSG sends a RADIUS accounting-request record to the local RADIUS server when a user logs in to or out of the SSG. The Acct-Status-Type attribute included in the accounting-request record indicates if the accounting-request marks the start of the user service or the end of the service.

When a user logs in, SSG sends an accounting-start record to RADIUS. When a user logs out, SSG sends an accounting-stop record.

Configuration Examples for Account Login and Logout

Example 4-3shows the information contained in a RADIUS accounting-start record.

Example 4-3 RADIUS Accounting-Start Record

Acct-Status-Type = Start

NAS-IP-Address = ip_address

User-Name = "username"

Acct-Session-Id = "session_id"

Framed-IP-Address = user_ip

Proxy-State = "n"

Example 4-4shows the information contained in a RADIUS accounting-stop record.

Example 4-4 RADIUS Accounting-Stop Record

Acct-Status-Type = Stop

NAS-IP-Address = ip_address

User-Name = "username"

Acct-Session-Time = time

Acct-Terminate-Cause = cause

Acct-Session-Id = "session_id"

Framed-IP-Address = user_ip

Proxy-State = "n"

The Acct-Session-Time attribute indicates the length of session, expressed in seconds. The Acct-Terminate-Cause attribute indicates the reason for account termination, which can be due to the following events:

•User-Request

•Session-Timeout

•Idle-Timeout

•Lost-Carrier
