Big-IP is a product of F5 Networks, an Application Delivery and Networking Company in US, a widely used tool, which ensures that applications are running fast, securely and is reliably available on the network. Big-IP is the world’s most comprehensive application delivery tool.

After applying for an SSL certificate you will receive it via e-mail, which contains 3 certificate files – your primary server certificate, a root certificate identifying the SSL provider, and an intermediate certificate. Once you have downloaded these 3 certificate files you will need to copy them onto your Big-IP controller.

For F5 Big-IP version below 9.x:

As discussed in Step 1 above, download your primary, intermediate and root certificate. Here, you only need the primary server certificate and intermediate certificate for the installation process on your F5 Big-IP device.

Perform following steps:

(1) Using FTP (File Transfer Protocol) move your Primary and Intermediate certificates onto your F5 Big-IP device.

(2) Rename your primary certificate with ‘yourdomain.crt’ and copy it into the ‘/config/bigconfig/ssl.crt/’ folder on your F5 Big-IP device. Follow the same process to copy your Intermediate-ca.crt certificate (sometimes also called CA1-Certificate or CA2- Certificate) into the/config/bigconfig/ssl.crt/’ folder on your F5 Big-IP device.

(3) Restart the Proxy by executing following commands:

(i) # bigpipe proxy :443 disable

(ii) # bigpipe proxy :443 enable

With this step, your certificate is successfully installed on your F5 Big-IP device.
