flowcontrol
Use this command to enable flow control. Use the no form to disable flow
control.
Syntax
flowcontrol
no flowcontrol
Default Setting
Flow control enabled
Command Mode
Interface Configuration (Ethernet, Port Channel)
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 802.3x 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 will be determined by the capabilities command. To
enable flow control under auto-negotiation, “flowcontrol” must be
included in the capabilities list for any port
• Avoid using flow control on a port connected to a hub unless it is
actually required to solve a problem. Otherwise back pressure jamming
signals may degrade overall performance for the segment attached to
the hub.
