Note For details about the command settings and the resulting flow control resolution on local and remote
ports, refer to the flowcontrol interface configuration command in the command reference for this
release.
Beginning in privileged EXEC mode, follow these steps to configure flow control on an interface:
Command
Step 1 configure terminal
Step 2
interface interface-id
Step 3
flowcontrol {receive | send} {on | off | desired} Configure the flow control mode for the port.
Step 4 end
Step 5 show interfaces interface-id
Step 6
copy running-config startup-config
To disable flow control, use the flowcontrol receive off and flowcontrol send off interface configuration
commands.
This example shows how to turn off all flow control on a port and to display the results:
Switch# configure terminal
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# flowcontrol receive off
Switch(config-if)# flowcontrol send off
Switch(config-if)# end
Switch# show running-config

Adding a Description for an Interface

You can add a description about an interface to help you remember its function. The description appears

receive off and send on: The port sends pause frames if the remote device supports flow control but
cannot receive pause frames from the remote device.
receive off and send desired: The port cannot receive pause frames but can send pause frames if the
attached device supports flow control.
receive off and send off: Flow control does not operate in either direction. In case of congestion, no
indication is given to the link partner, and no pause frames are sent or received by either device.
Purpose
