H OTS POT GATEWAY280 Quick Reference GuideSelected Detailed DescriptionsAcct-Session-IDThe Acct-Session-ID is created when the RADIUS authentication request is built. It istransmitted in both the Access-Request and the Accounting-Request.Session TimeoutThere is currently no default session timeout that you can set in the HSG WebManagement Interface (WMI). If the Radius server does not send a Session-Timeout,the HSG will set the subscriber expiration time to 0, which means access forever.Log-Off-URLAllows for the placement of a log off URL (for example, 1.1.1.1) on an external portalpage.Idle TimeoutThe WMI allows the setting of a default timeout. If the Radius server does not send anIdle-Timeout in the Radius Access-Accept, the HSG will use the default one todisconnect subscribers. “0” means forever.Timeout DetectionIf a subscriber is sending traffic through the HSG, the HSG will immediately detect aSession-Timeout. However in the case of an Idle-Timeout or an inactive subscriberSession-Timeout, the HSG detects it via a clean-up function that is currently calledevery 2 minutes. Thus the current precision for sending the Acct-Stop is about 2minutes.Subscriber Session DurationAcct-Session-Time is calculated the following way (for each transmitted/retransmitted Acct-Stop):Acct-Session-Time = time of last sent packet - subscriber login time.Another attribute, Acct-Delay-Time, will take into consideration the time spent inretransmissions.
