I am currently planning to implement 802.1X authentication for all the wired computers at the office where I work at currently.
We have successfully implemented 802.1X authentication with login/password credentials. It authenticates against a RADIUS server. The RADIUS server is a Microsoft IAS.
Alongside the wired network, we have an ARUBA wifi controller which does 802.1X authentication with certificates.
We are wishing to use the same certificates to authenticate wired computers. This just does not seem to work. The problem seems to be at the Cisco switch level. The computer sends the credentials to the switch but the switch just ends the EAP session with an error. The RADIUS server is never contacted.
There my question is the following : do Cisco switches support 802.1X EAP authentication with certificates ? If yes, what are the specifics to this type of setup ?
Thank you in advance for your help,
