Viewing fast-ethernet Interface information.
The fast-ethernet interface information may be viewed using the ‘show’ command. The
“show run” command displays the intended configuration of the interface, while the
“show interface fast-ethernet” command displays the current state of the interface.

MTU (Maximum Transmission Unit) is the threshold at which single layer-3 IP packets become
fragmented into multiple, smaller-size packets.
