Each interface on the BIG-IP® system has a set of properties that you can configure, such as enabling or disabling the interface, setting the requested media type and duplex mode, and configuring flow control. Configuring the properties of each interface is one of the first tasks you do after running the Setup utility on the BIG-IP system. While you can change some of these properties, such as media speed and duplex mode, you cannot change other properties, such as the media access control (MAC) address.
Before configuring interface properties, it is helpful to understand interface naming conventions. Only users with either the Administrator or Resource Administrator user role can create and manage interfaces.
