3.63 flowcontrol

This command is used to set the send or receive flow-control value for an interface. If flow control
send is on for a device, and if it detects any congestion at its end, then it will notify the link partner
or the remote device of the congestion by sending a pause frame.
If flowcontrol receive is on for the remote device and it receives a pause frame, then it stops
sending any data packets. This prevents any loss of data packets during the congestion period.
You can use both the receive off and send off keywords to disable flow control.
flowcontrol { send | receive} { on | off }
