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 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 VF-45 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.
