i schould run 802.1x certificate on all of the our switch and see their log in our ISE server.
at first , i did these cenario mit one test switch. i konfigured 802.1x on test switch and connect telephon , laptop and printer to my test switch and could see their log in ISE Server.
but when i did this config in real network , ( that the model and ios of switch is the same, and all of the config is the same too ), i couldn't receive log in ISE.
I can ping ISE ip from my network switch.
