• 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.
