NAD RADIUS password does not support special characters - ISE 2.1

[gvoden4prez]

Just upgraded from ISE 1.4 to 2.1 and I am getting this error when using my usual NAD RADIUS password for my switches:

You have entered text that appears to contain unsupported tags or markup language. Remove those characters and try again.

This is in my lab, however its a major show stopper as I have over 300 switches in my PROD environment which is on ISE 1.4. Upgrading to 2.1 means I have to change the RADIUS password on all of them and have potential impact.

Please provide a sample shared secrete that triggers this issue and the list of special characters you normally used for this purpose. Are you seeing the same with CSV import?

[gvoden4prez]

The shared secret begins with {'

What is interesting is that I have over 100 switches pre-configured before the 2.1 upgrade and they imported fine with a special character shared secret. I haven't tested the CSV import on 2.1 yet.

The issue is with the single quote character and CSV imports working fine for me as a workaround.

This is a known bug -- CSCuz19346    Shared secret with ' character on ISE 2.0 fails.

Ok thanks so much for the info, as I mentioned above the bug still exists in version 2.1.

Will be using the CSV import until fixed.
