Command Usage
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.
Example
The following example enables flow control on port 5.
Console(config)#interface ethernet 1/5
Console(config-if)#flowcontrol
Console(config-if)#
