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.
Flow Control A concentration of traffic on a port decreases port bandwidth and overflows
buffer memory causing packet discards and frame losses. Flow Control is used to
regulate transmission of signals to match the bandwidth of the receiving port. The
Switch uses IEEE 802.3x flow control in full duplex mode and backpressure flow
control in half duplex mode.
IEEE 802.3x 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 packet collision)
causing the sending port to temporarily stop sending signals and resend later.
