Blacklisting certificates by certificate id

Hello Don!

 

 

It looks like all I have is just the certificate ID, and not the certificate itself, so I'm not sure if this is what I need.

 

 

I want to be sure I am not using incorrect terminology, so I'm going to avoid using the word Blacklist. What do I need to do to make F5 reject a client (which provides a cert) from connecting? Is there anyway I can simply mark the cert as deactive? Later on, I can mark it as active again so that F5 accepts connections from that client?

 

 

Thank you again for all your assistance so far.
