Broadcast Storm Control
The switch implements a broadcast storm control mechanism. Tick the check boxes to have
them beginning to drop incoming broadcast packets if the received broadcast packet counts
reach the threshold defined. Each port’s broadcast storm protection function can be enabled
individually by ticking the check boxes.

The broadcast packet is only checked at the selected port and the number of broadcast
packets is counted in every time unit. The one time unit indicates the number of broadcast
packet which is allowed to enter each port in one time unit. The one time unit is 50us for
Gigabit speed, 500 us for 100Mbps speed and 5000us for 10Mbps speed. The excessive
broadcast packet will be discarded. For those broadcast packets incoming from the
un-selected port, the switch treats it as the normal traffic.
Threshold:
Type in the threshold in the range between 1 and 63 to limit the maximum
byte counts, which a port can send or receive in a period of time.
Enable Port:
Having ticked the boxes, the port will stop transmitting or receiving data
when their sending byte counts or receiving byte counts reach the defined threshold.
Example to change one time unit to pps:
The port 1 is 100M port. The one time of it is 500us It indicates there are 2,000 packets can be
sent within one second. While type 10 to port 1, that means 10x2000 packets can be sent in
one second.
