5.2.5 Flow
Control
In Ethernet networking, the flow control is the process of adjusting the flow of data from
one network device to another to ensure that the receiving device can handle all of the in-
coming data. For this process, the receiving device normally sends a PAUSE frame to the
sending device when its buffer is full. The sending device then stops sending data for a
while. This is particularly important where the sending device is capable of sending data
much faster than the receiving device can receive it.
To enable the flow control on an Ethernet port, use the following command.
