Hi All,

I would like to configure 802.1x authentication on both my Cisco ip phones and windows clients using NPS. So far i have tested the clients and it works however I am not finding any information on if NPS supports 802.1x on ip phones. Has anyone done a similar deployment using NPS. So far I am only seeing cisco ACS server being used as the policy server.

Hi,

Based on my research, it seems that you may enounter issues related to username(Basically Mircosoft only allows a 20 character user name, while the user name of the phone exceeds the 20 character limit and causes it to fail.) and certificate schema when configuring 802.1x authentication for Cisco IP phones.

Best regards,

Susie
