• 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.
