Has anyone ever tested a dot1x configuration with cisco acs and nexans switch? I don't see any failed attempts in the acs log files. In the nexans log it seem's to be that the radius server is down. Why ever. If i configure radius authentication for the admin access over the telnet interface, the radius authentication is functional. I have tested the dot1x configuration with a cisco switch and this working also. The customer search for switches for a cable channel. This is the reason for using nexans, before any question occur.
I have this problem too.
