From the Flow Control menu, select to enable or disable IEEE 802.3 flow control.

The default is Disable. The switch does not send pause frames if the port buffers become
full. Flow control helps to prevent data loss when the port cannot keep up with the number
of frames being switched. When enabled, the switch can send a pause frame to stop
traffic on a port if the amount of memory used by the packets on the port exceeds a
preconfigured threshold and responds to pause requests from partner devices. The
paused port does not forward packets for the period of time specified in the pause frame.
When the pause frame time elapses, or the utilization returns to a specified low threshold,
the switch enables the port to again transmit frames. For LAG interfaces, flow control
mode is displayed as blank because flow control is not applicable.
In the Load Interval field, specify the load interval period for which data is used to compute

load statistics.
Enter the interval in multiples of 30 seconds. The allowable range is 30 to 600. The
default load interval is 300 seconds. The smaller the load interval is, the more accurate
the instantaneous rate for load statistics is.
Click the Apply button.
