DESCRIPTION
Use this to enable or disable flow control.
A concentration of traffic on a port decreases port bandwidth and
overflows buffer memory causing frame discards and frame
losses. Flow Control is used to regulate transmission of signals
to match the bandwidth of the receiving port.
The Switch uses IEEE802.3x flow control in full duplex mode and
backpressure flow control in half duplex mode.
IEEE802.3x flow control is used in full duplex mode to send a
pause signal to the sending port, causing it to temporarily stop
sending signals when the receiving port memory buffers fill.
Back Pressure flow control is typically used in half duplex mode to
send a "collision" signal to the sending port (mimicking a state of
frame collision) causing the sending port to temporarily stop
sending signals and resend later. Select Flow Control to enable
it.
