Interface Speed and Duplex Mode

Ethernet interfaces on the switch operate at 10, 100, or 1000 Mb/s and in either full- or half-duplex mode. In
full-duplex mode, two stations can send and receive traffic at the same time. Normally, 10-Mb/s ports operate
in half-duplex mode, which means that stations can either receive or send traffic.
Switch models include Gigabit Ethernet (10/100/1000-Mb/s) ports and small form-factor pluggable (SFP)
module slots supporting SFP modules.
