Use the flow control command to configure flow control to operate in TxRx mode on the current port.  

Use the undo flow-control command to disable flow control on the port.  

A port configured with the flow-control command can not only receive and process remote pause 

frames, but also send pause frames actively when the port is congested.  

By default, flow control is disabled on Ethernet ports.  

# Enable flow control on the Ethernet 1/0/1 port.
