Hi Hoang,

 

>> I think it will Impact all running service on F5 deivice. We on apply on Management Interface..

Please recommend to you

 

ANS: It will not impact all the services. It only applies to management GUI interface(configuration Utility) which is accessed via HTTPS.

 

Here is the documentation from F5 your conformation.

>> we only reconfig on Management interface.

 

May be you are thinking  Configuration utility and Management Interface are 2 different things. F5 calls Management interface as  Configuration utility.

 

"Configuration utility = Management Interface"

 

Therefore, following article is for management interface.

K42531434: Replacing the Configuration utility's self-signed SSL certificate with a CA-signed SSL certificate

Hope this helps.

Thank you
