4.5.1. Capture frame
Interface
This field specifies the interface you want to capture on. You can only capture on one interface, and you can only capture on interfaces that Wireshark has found on the system. It is a drop-down list, so simply click on the button on the right hand side and select the interface you want. It defaults to the first non-loopback interface that supports capturing, and if there are none, the first loopback interface. On some systems, loopback interfaces cannot be used for capturing (loopback interfaces are not available on Windows platforms).
This field performs the same function as the -i <interface> command line option.
