I don't believe this is controlled by FreeRadius itself but I am kind of at a loss figuring out where it might be configured. I have Freeradius acting as an AAA server for a Cisco 2960 L2 switch as well as a Cisco Wireless LAN Controller. Working on setting up Accounting which for the most part works. However I am unable to determine what causes the Interim-Update Acct-Status-Type message to be sent. Checking the detail log (have that module turned on in accounting section) I have seen those messages present. In fact earlier in the day connected clients sent a few Interim-Update messages (one was 1 second apart, than 10 seconds apart, than 30 seconds apart). That happened early this morning. However ever since that I have not seen any Interim-Update accounting messages. I read through the 802.1x configuration guide for the 2960 and it just talks about the Interim-Update message being sent but doesn't list of a way to specify the interval (assuming that interval is specified on the switch side). Any help would be appreciated. Thanks
