Enabling or Disabling Flow Control
A switch port uses flow control to control the flow of ingress packets from
its end node. Flow control applies only to ports operating in full-duplex
mode.
A port using flow control issues a special frame, referred to as a PAUSE
frame, as specified in the IEEE 802.3x standard, to stop the transmission
of data from an end node. When a port needs to stop an end node from
transmitting data, it issues this frame. The frame instructs the end node to
cease transmission. The port continues to issue PAUSE frames until it is
again ready to receive data from the end node.
The default setting for flow control on a switch port is disabled.
