INTERFACE COMMANDS

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.

To force operation to the mode specified in a flowcontrol command, use the no negotiation command to disable auto-negotiation on the selected interface.

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.

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.

Due to a hardware limitation, flow control only works on those ports located in the same chip (ports 1-12 and ports 13-24). Cross-chip flow control does not work.

Example

The following example enables flow control on port 5.

Console(config)#interface ethernet 1/5

Console(config-if)#flowcontrol

Console(config-if)#no negotiation

Console(config-if)#
