Syntax Description
[no] flowcontrol
Default

Command Mode
Interface Configuration (Ethernet, Port Channel)
Usage Guidelines
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
802.3x 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 negotiation command to enable auto-negotiation, the optimal settings is determined by the
capabilities command. To enable flow control under auto-negotiation, “flowcontrol” must be included in the
capabilities list for any port
