Hi,
I' have realy big layer two access network made of etherogenius Cisco switch with different IOS version and train.
My customer bought ISE (ADVANCED AND BASE LICENSE).
As far I read on DS it is seem that if you have Minimum IOS release 12.2(52) SE you are able to perform COA, reading DS with more attention I notice that cisco raccomend IOS versione 12.2(55)SE3 why ? does it means COA does not work with 12.2(52)SE ?
But more important :
I need a minimum IOS release to perform 802.1x on my wired network ?
