Add authentication policy for external clients in ISE TACACS 3.0

sbartelt62

Level 1

We have ISE TACACS 3.0 in our company. I am new to administering the environment. We have an external AD environment that clients can authenticate against. In our authentication Policy we have MAB, Dot1X and Default. Would a new policy be added prior to Default to allow clients to authenticate against the external AD environment?

hello @sbartelt62 , within the scenario that you are describing you need to create a policy in which you will be using dot1x , depends mostly on the design you want to do with your policies sets ,  you can place , as you mention,  a policy set  above the default one where you might indicate that devices doing this protocol will be hitting the rule , as the following example shows

The rules on ISE are evaluated from top to bottom so the rules that you have above will be evaluated first , you can add multiple more conditions within the rules that adapt to the authentication you want to achieve ,  or you can also work within the default rule and create a condition that is specific for dot1x within the "Authentication policy" section of that policy set ,  for ISE 3.0 also you need to have essential licensing to perform RADIUS AAA and web authentication . 

Kindly refer to the following links that may help you in this new configuration
