We are running the cisco ise 1.1.3 and configured for the Dot1x and MAB authentications. PC's are getting access through MAB while Dot1x failing again and again. But, sometime, same PC is getting authenticating via Dot1x. Connectivity is intermittent. Also, sometimes, stucks longer in Posture
We have three different switches at the moment with the latest IOS version.
1) WS-C4507R-E = 15.1(2)SG,
2) WS-C3560-48PS = 12.2(55)SE7
3) WS-C3750X-24P = 15.0(2)SE1
Could you anyone pitch the idea? or advise about the latest IOS for the switches.
Let me know, if you need more information.
