Changing the Flow Control Setting
A switch port uses flow control to control the flow of ingress packets from
its end node. Flow control applies to ports operating in full-duplex mode. A
switch port uses flow control to control the flow of ingress packets from its
end node. 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 ready again to receive data from the end node.
The default setting for flow control on a switch port is disabled.
To change the flow control setting on a port, perform the following
procedure:
1. From the Main Menu, type B to select Basic Configuration.
The Basic Switch Configuration Menu is shown in Figure 4 on page 32
2. From the Basic Switch Configuration Menu, type P to select Port
Configuration.
The Port Configuration Menu is shown in Figure 17 on page 70.
3. Type F to select Flow Control.
The following prompt is displayed:
Set Flow Control -> Enter port number >
4. Enter the port number whose flow control setting you want to change.
You can configure only one port at a time.
The following prompt is displayed:
Enable or Disable flow control for port
n
(E/D)>
5. Type E to enable flow control or D to disable it. The default is enabled.
The display is refreshed to show the port’s new flow control setting.
