Note: MT-RJ ports operate at 100 Mbps and support full- and half-duplex
mode. 100BASE-FX module ports operate at 100 Mbps,
full-duplex only. 1000BASE-SX and 1000BASE-LX ports are fixed
at 1000 Mbps, but auto-negotiate duplex mode and flow control.
1000BASE-T ports auto-negotiate speed (1000/100/10 Mbps),
duplex mode and flow control.
Flow Control
Status
Disabled Used to enable or disable flow control. Flow
control can eliminate frame loss by “blocking”
traffic from end stations or segments connected
directly to the switch when its buffers fill. Back
pressure is used for half duplex and IEEE 802.3x
for full duplex. Note that flow control should not
be used if a port is connected to a hub.
