The new maximum rate is displayed on the Advanced Port Configuration menu.

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. The port must be configured to operate in Full Duplex mode. If you enable flow control on a port which is overwhelmed (run- low in the buffer resources), that port will transmit PAUSE frames; the link partner will obey the PAUSE frame. When the low-resource situation is relieved, the port sends out PAUSE frames with zero time value to un-pause 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.

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

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

4 Type f to toggle flow control for the selected port.

The flow control symbol for the selected port reflects its change in state, as does the 802.3x Flow Control setting.

▲Important: The link partner must be configured to recog- nize PAUSE frames when using this method of flow con- trol.

Setting Port Default Priority

Use the following procedure to set a higher or lower priority for a port. This priority setting determines the order in which the port forwards packets. Each port is associated with a traffic class; 0 (zero) is the lowest, and the default priority level, and 1 is the highest priority level.

1 Access the Port Configuration menu by typing p in the Configuration menu.
