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 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. IEEE 802.3x flow control
is used for full duplex. Note that flow control should
not be used if a port is connected to a hub.
Speed and
Duplex
100_FULL Used to set the current port speed and duplex mode.
The MT-RJ ports have a default setting of 100_FULL.
Auto-negotiation is the default setting for
1000BASE-T, 1000BASE-SX and 1000BASE-LX;
but is not available for 100BASE-FX.
