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 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 packet collision)
causing the sending port to temporarily stop sending signals and resend
later. Select Enable to turn this feature on or select Disable to turn it off.
Default
Priority
This priority value is added to incoming frames without a priority queue
tag.
PVID Enter a number identifying an existing VLAN. The Switch tags the incoming
untagged frames on that port so that the frames are forwarded to the
VLAN group that the tag defines.
