Any one know where you load the CA Certiricate for PEAP if you use ISE as a radius server ?
Jonny provided the section to install the ISE "Identity Certificate" issued by a CA for the ISE itself. I provided the section to install the Certification Authority (Root) certificate. Adding the clarification to avoid any confusion.
You need to select Administration->System-Certificates->Local Certificates
Add the certifcate you want to use. When adding select the following option under Protocol "EAP: Use certificate for EAP protocols that use SSL/TLS tunneling"
This will define the server certificate to be used for PEAP protocols
Adding a Certificate Authority Certificate
Step 1 Choose Administration > System > Certificates.
Step 2 From the Certificate Operations navigation pane on the left, click Certificate Authority Certificates.
The Certificate Authority Certificates page appears.
Step 3 Click Add.
Hope this helps.
