Hi, A couple of questions on Acct-Interim-Interval 1. I wanted to know if the Acct-Interim update that comes from the NAS has any relevance as far as the user session maintained in the radius server is concerned. Meaning that is it treated like a keep-alive of some sort. If the Acct-Interim-Interval is configured to be 100 seconds and the NAS sends the Interim-Update after 200 seconds does the freeradius server care ? 2. What is the typical value of this attribute, I ask because if this value is configured to be small then it will generate a lot of interim updates from a NAS that supports large number of subscribers. At the same time I am not sure how the service providers who deploy the server use this Attribute and how often do they want the updates. Thanks, Vinay
