Full-duplex mode is supported for all 10/100 Mbps ports and allows the port to transmit and
receive data at the same time. Full-duplex operation applies only to point-to-point access (for
example, when a switch is connected to a PC, a server, or another switch).
Setting the toggle switch to AUTO on the 10/100 Mbps port enables the port to determine duplex
mode automatically. In this mode, the 10/100 Mbps port operates in either full- or half-duplex
mode, depending on the operating mode of the remote port. If the remote port cannot provide the
proper signal to indicate its own capability, the 10/100 Mbps port on the switch will default to
half-duplex mode. Because repeaters and hubs use a common collision domain for all
communications and cannot communicate in full-duplex mode, the associated 10 Mbps port on the
switch should be set to auto-duplex operation when connecting to these types of devices.
