Switch Port Configuration Menu

The Switch Port Configuration menu, displayed in Figure 23, enables you to change the
configurations of individual ports.

Figure 23: Switch Port Configuration menu

State

All ports have two states: enabled or disabled. Enabled ports transmit and receive data
packets. Disabled ports can not transmit or receive packets. You can disable a port but you
will not be able to use a disabled port.

Physical

Refers to the physical state of the port. If you manually change the state of a port it will
remain in that state until you change it. It will not auto negotiate speed and duplex mode. All
ports can be in the following physical states:

•

Auto

•

100Tx/Half

•

100Tx/Full

•

10Tx/Half

•

10Tx/Full

Ports in the Auto state automatically negotiate speed and duplex mode. This is the default
setting.

Ports set in the 100Tx/Half physical state are set to work at 100 Mbps half duplex.

Ports set in the 100Tx/Full state are set to work at 100 Mbps full duplex.
