Hi,
In order to create CSR file from the ISE using a wildcard certificate, you can do the following:
From the CSR page, enter the CN=*.yourdomain.com
and If you have a specific DNS entry for your ISE like ise1.yourdomain.com under the SAN fields.
Also, you need to check the box of "Allow Wildcard Certificate".
After that, you can generate and export the CSR and submit it to your CA to get the ID certificate (which you will bind it with the CSR).
Also, you need the CA certificate itself to be added on the ISE certificate store.
Thanks.
Ahmad.
