Enabling or Disabling 802.3x Flow Control

Use the following procedure to control traffic and avoid congestion, such as when there is a shortage of buffer resources for the port. Flow control is accomplished by means of standard PAUSE control frames for each port, independent of all others. Before you can enable flow control for a port, that port must be configured to operate in Full Duplex mode.

If you enable flow control on a port, and that port runs short of buffer resources, the port will transmit PAUSE frames. When it receives them, the link partner obeys these PAUSE frames. When the low-resource situation is relieved, the port sends out PAUSE frames with zero time values. This ends the pause staste that was imposed on the end-station.

To enable flow control, first access the Port Configuration Menu by typing p in the Configuration Menu, then take the following steps.

1

2 In the Basic Port Configuration Menu, type a to open the Advanced Port Configuration Menu.

3 To select the port for which you want to enable or disable flow control, type s, n, or p.

4 To toggle flow control for the selected port, type f.

In the Advanced Port Configuration Menu, the Flow Control symbol for the selected port reflects its change in state, as does the 802.3x Flow Control setting.

IImportant: When using this method of flow control, the link partner must be configured to recognize PAUSE frames.
