    Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years.  I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

WLC: Radius Statistics Command

It is always nice to get emails from twitter and blog peeps. I received an email from Bruce from Erie, PA asking:

 Hi George,

Have been enjoying reading the various information you have posted… but haven’t seen anything yet on one of my favorite autonomous commands that I haven’t found a WLC equivalent yet.

sh aaa server

Since we normally have 3 ACS servers defined on all implementations, this simple command lets me see quickly (after running “clear aaa counters server all”) which specific ACS server I should be looking on for failure/success logs.  On WCS/WLC, I have yet to find anything so simple to quickly get me that information.

If you are aware of a WLC version of it, would love to see it covered as a topic.  And if not, I still find my80211 to be very useful and enjoyable!  Keep up the good work.

Thanks,
Bruce

RADIUS Statistics

Bruce, my friend, you are in luck! The following commands are the equivalent commands on the WLC

>show radius auth statistics

>clear stats radius auth all

 

Good information

When troubleshooting radius issues these stats come in handy! When your radius server is on the blink or if there is a configuration issue somewhere in the 'line' you can see if anything is passing through the WLC.  Remember the WLC acts as the "authenticator" and simply passes the EAP packets between the client and the radius server "authentication server". No real heavy lifting is done by the WLC during this process.
