3-45
Note: VF-45 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.
