The SSL Visibility Appliance comes with 2 Management Interfaces at the back of the appliance, Management Interface 1 and Management Interface 2.
You want to use Management Interface 2.
The second interface (Management Interface 2) cannot be used currently.
You cannot configure or use this interface. We may use this interface in the future to support additional features in the SSL Visibility Appliance software but at the time of writing, it is not used and is not accessible.
Use only Management Interface 1.
