To install your EV Web Server Certificate on Big IP F5 9.x follow the instructions below:
This document provides instructions for installing Thawte SSL Web Server Certificates. If you are unable to use these instructions for your server, Thawte recommends that you contact either the vendor of your software or an organization that supports Big IP F5 9.x.
Step 1: Obtain the Thawte EV Web Server Intermediate CA certificate
Note: In a redundant system, the keys and certificates must be in place on both controllers before you configure the SSL Accelerator. You must do this manually; the configuration synchronization utilities do not perform this function.
Step 2: Install the EV Certificate
Step 3: Establish the trust chain: The proper Intermediate CA certificate must be set to ensure a complete chain of trust.
Create the SSL Profile
Select the proper certificate and CA
Open the SSL Profile
Within the Configuration, select Advanced
Select the appropriate certificate for your website
Select the corresponding private key
Within Trusted Certificate Authorities or Chain, select the Intermediate named "EV_intermediate"
Save and Close Properties
NOTE: Please refer to the screenshot of the F5 Big-IP interface
