Chapter 8 Basic Setting Figure 50 Basic Setting > Port Setup The following table describes the labels in this screen. Table 14 Basic Setting > Port Setup LABEL Port DESCRIPTION This is the port index number. * Settings in this row apply to all ports. Use this row only if you want to make some settings the same for all ports. Use this row first to set the common settings and then make adjustments on a port-by-port basis. Active Name Note: Changes in this row are copied to all the ports as soon as you make them. Select this check box to enable a port. The factory default for all ports is enabled. A port must be enabled for data transmission to occur. Enter a descriptive name that identifies this port. You can enter up to 64 alpha-numerical characters. Type Speed/Duplex Note: Due to space limitation, the port name may be truncated in some web configurator screens. This field displays the capacity that the port can support. Select the speed and the duplex mode of the Ethernet connection on this port. Choices are Auto, 10M/Half Duplex, 10M/Full Duplex, 100M/Half Duplex, 100M/Full Duplex and 1000M/Full Duplex (Gigabit connections only). Selecting Auto (auto-negotiation) allows one port to negotiate with a peer port automatically to obtain the connection speed and duplex mode that both ends support. When autonegotiation is turned on, a port on the Switch negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer port does not support autonegotiation 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 autonegotiation is turned off, a 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 port are the same in order to connect.
