always be used to establish a connection over any 1000BASE-T port or

Flow control can eliminate frame loss by "blocking" traffic from end
stations or segments connected directly to the switch when its buffers
fill. When enabled, back pressure is used for half-duplex operation and
IEEE 802.3-2002 (formally IEEE 802.3x) for full-duplex operation.
To force flow control on or off (with the flowcontrol or no flowcontrol
◆
command), use the no negotiation command to disable auto-
negotiation on the selected interface.
When using the

optimal settings will be determined by the
