Full-duplex mode operation only applies to point-to-point access (for example, when attaching
the Switch to a workstation, server, or another switch). When connecting to hubs, use a
standard cascaded connection set at half-duplex operation.
Auto-negotiation regulates the speed and duplex of each port, based on the capability of both
devices. When auto-negotiation is turned on, an Ethernet port on the Switch negotiates with
the peer automatically to determine the connection speed and duplex mode. If the peer
Ethernet port does not support auto-negotiation or turns off this feature, the Switch determines
the connection speed by detecting the signal on the cable and using half duplex mode. When
the Switch’s auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and
duplex mode when making a connection, thus requiring you to make sure that the settings of
the peer Ethernet port are the same in order to connect.
Use this screen to configure Switch port settings. Click Basic Setting > Port Setup in the
navigation panel to enter the port configuration screen.
