Table 11 Basic Setting > Port Setup
LABEL DESCRIPTION
Port 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.
Note: Changes in this row are copied to all the ports as soon as you
make them.
Active 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.
Name Enter a descriptive name that identifies this port. You can enter up to 64 alpha-
numerical characters.
Note: Due to space limitation, the port name may be truncated in
some web configurator screens.
Type This field displays 10/100M for an Ethernet/Fast Ethernet connection and 10/100/
1000M for Gigabit connections.
Speed/Duplex 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 (for Gigabit ports 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 auto-negotiation 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 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, 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.
