FastEthernet 100 Mbit interface usually also supports 10 Mbit and have the
ability to auto-sense speed.
FastEthernet0/0 is up = Indicates weather the the interface hardware is currently active.
line protocol is up = Indicates weather the software process that handles the line protocol detects that the hardware is usable and its state.

Hardware is AmdFE,
address is 0006.28aa.0a40 (bia 0006.28aa.0a40)
The MAC (Media Access Control)
address. A unique 24 bit number, in hexadecimal,
assigned to
every network interface that attaches to a network. The first six digits
represent the manufacturer of the card, the last six are assigned by the
manufacturer usually the serial number.
Internet address is 172.30.1.254/24
MTU (Maximum Transmission Unit) A maximum transmission unit (MTU) is the largest size packet or frame, specified in octets (eight-bit bytes), that can be sent in a packet- or frame-based network. The Internet's Transmission Control Protocol uses the MTU to determine the maximum size of each packet in any transmission.
BW 100000 Kbit, Bandwidth is the amount of data that can be transmitted in a fixed amount of time. The capacity of the interface.
