Cisco ISE 802.1X Configuration

AbrarMukit — Fri, 02 Sep 2022 00:46:48 GMT

Hi, I am new to Cisco ISE. Trying to set up authentication and authorization based on the certificate but it's not working. I have configured my router for the AAA model as well my test laptop got a certificate. I have uploaded the same root cert to cisco ISE as a trusted cert.

When it's authenticating its using the MAB authenticating method instead of 802.1x

If it’s going mab then make sure your supplicant (endpoint) is properly configured for EAP-TLS. The picture you attached is blurr so I can not confirm your policy.

follow this guide, even if you have different version of ISE concept is same : https://www.cisco.com/c/en/us/support/docs/security/identity-services-engine/214975-configure-eap-tls-authentication-with-is.html

Hi @AbrarMukit ,

please double check your NAD configuration, special attention to the:

(config-if)# authentication order dot1x mab
(config-if)# authentication priority dot1x mab

also, use the debug radius all to check EAP packets from the Endpoint to the NAD.

Hope this helps !!!

Thats what it giving when I am trying to configure the NAD
Switch(config-if)#authentication order dot1x mab
Command deprecated (authentication order dot1x mab) - use cpl config
