Enable port
Disable port
This selection allows you to manually disable a port in the module so
that it no longer receives or sends packets. You might want to disable
a port if a problem occurs with the end-node or cable connected to
the port. Once the problem has been fixed, you can enable the port
again to resume normal operation. You can also disable an unused
port to secure it from unauthorized connections. Enable port is the
default setting.
Full duplex
The port can both send and receive data simultaneously. You can
select this setting for a port if you know that the end-node connected
to the port supports full-duplex.
Half duplex
The port can send or receive data, but not both at the same time. Use
this setting if you know that the device connected to the port
supports half-duplex mode.
Auto negotiate
The port negotiates with the connected device to automatically
configure to the highest common setting. This setting eliminates the
need to reconfigure the port if you change the type of device
connected to the port. Both end devices need to be auto-negotiation
compliant (802.3u) for the best possible performance settings. If a
connected device is not compliant, it should only be configured for
half-duplex. Auto-negotiate is the default for all ports.
Hundred Base (100BaseTX)
Ten Base (10BaseT)
This selection controls the speed of the ports.
