Broadcast Storm Control

The broadcast storm control is used to block excessive broadcast packets. If the number of
broadcast packets exceeds the defined threshold during one time unit, all excessive
broadcast packets will be dropped. The time unit is 500

μs for 100 Mbps link speed and

5000

μs for 10 Mbps link speed.

Each port’s broadcast storm protection function can be enabled individually.

Example:

In the picture below, the Broadcast Storm Control is enabled for ports 1~6 and threshold is
set to 10. If the number of broadcast packets exceeds the threshold setting, all

excessive

packets will be dropped (packet length is 64 bytes).

How to change one time unit to pps:

The port 1 is 100M port. The one time unit of it is 500

μs, it indicates that 2000 packets can

be sent within one second. Setting the threshold 10 for port 1 means that 10x2000 packets
can be sent in one second.
