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 Fast Ethernet connections 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 (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 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.
