SMC Networks 1000BASE-X Manual De Usuario

3-47

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.
