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.

Example

The following example enables flow control on port 5.

Related Commands
