Configuring the Flow Control

For Ethernet ports that run at 1 Gb/s or faster, you can enable or disable the port's ability to send and
receive flow-control pause frames. For Ethernet ports that run slower than 1 Gb/s, you can enable or
disable only the port's ability to receive pause frames.
When enabling flow control for the local port, you either fully enable the local port to send or receive
frames regardless of the flow-control setting of the remote port, or you set the local port to use the
desired setting used by the remote port. If you enable both the local and remote port for flow control, or
set the desired flow control of the other port, or set a combination of those two states, flow control is
enabled for those ports.
Note For ports that run at 10 Gb/s, you cannot use the desired state for the send or receive parameter.
BEFORE YOU BEGIN
Make sure that the remote port has the corresponding setting for the flow control that you need. If you
want the local port to send flow-control pause frames, make sure that the remote port has a receive
parameter set to on or desired. If you want the local port to receive flow-control frames, make sure that
the remote port has a send parameter set to on or desired. If you do not want to use flow control, you can
set the remote port's send and receive parameters to off.
