4-150

• 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.

negotiation (4-147)
capabilities (flowcontrol, symmetric) (4-148)

This command disables an interface. To restart a disabled interface, use the 
no form.

[no] shutdown

All interfaces are enabled.
