I don't think we measure speed but have looked at the RADIUS wait queue on our Cisco wireless controllers. There are only 256 slots available to process, so we have 6 FreeRADIUS servers load balanced by an F5 to trying to complete as many transactions as fast as possible. Bad authentications can really slow things down. Our peak times are at class changes when hundreds or thousands(?) of wireless devices start changing location. We can max out 4 servers at those points.

How fast is fast enough? How slow is unacceptable? We have Aruba Airwave, and its Clarity module provides me a way to measure the amount of time that RADIUS Authentication takes. For our RADIUS MAC SSID's it says it takes 63ms, and for our 802.1x SSID it says 2392ms. The settings Airwave comes with by default are that <500ms is marked green meaning good, 500 -- 1000ms is marked yellow meaning warning and >1000ms is marked read meaning poor. Of course faster is always better, but I wondered if others have opinions on whether Airwave's ranges are reasonable, or whether they have unrealisticly expectations. If they're reasonable, then I probably need to figure out how to speed up our 802.1x RADIUS performance. -- Adam Forsyth Director of Network and Systems Luther College Information Technology Services 700 College Drive Decorah, IA 52101 563-387-1402 ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.
