ACCESS GATEWAY
Quick Reference Guide 271
Subscriber Session Duration
Acct-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 in
retransmissions.
Interim Accounting Updates
The Access Gateway parses the attribute Acct-Interim-Interval in an Access-Accept. If this
attribute is present the Access Gateway tries every [Acct-Interim-Interval] seconds to send a
Radius Accounting Interim message for the specific subscriber. If this attribute is not present
or equal to 0, no Interim message is sent.
The precision is 2 minutes. The Access Gateway will not send Interim messages more
frequently than every 2 minutes.
Called-Station-ID
This is the Media Access Control (MAC) address of the Access Gateway.
Calling-Station-ID
This is the Media Access Control (MAC) address of the client's computer.
New Attributes in Acct-Request
The Access Gateway has to send the following attributes in an Accounting-Stop:
Acct-Output-Packets: number of packets sent by subscriber.
Acct-Input-Packets: number of packets received by subscriber.
Upon a reboot, these 2 attributes are saved in currfile.dat the same way as for Acct-Input-
Octets and Acct-Input-Octets.
