4. Change the port parameters as desired. The parameters are described
below:
1- TX/RX
This option allows you to manually disable or enable a port on the
switch so that it can no longer receive or send frames. You may
want to disable a port if a problem occurs with the end-node or
the cable connected to the port. Once the problem has been
fixed, you can enable the port again to resume normal network
operation. You can also disable an unused port to secure if from
unauthorized connections. Enable port is the default setting.
2 - Flow Control
When the port is operating in full-duplex mode, it will uses a
special pause packet to stop the end-node from sending frames.
The pause packet notifies the end-node to stop transmitting for a
specific period of time. The flow control allows the port to
decrease the frequency in which it is sending packets to the
receiving end-node, if packets are being sent to fast.
When the port is operating in half-duplex mode and flow control
is enabled and if the RX buffer becomes full, the switch will
produce a jamming signal. This jamming signal sends a collision
to the end-node notifying the end-node to stop sending packets
until the jamming signal is cleared.
