It is important to note that the maximum number applies to the egress
port of a broadcast frame, not the ingress port. That is, any port on the
switch will accept any number of broadcast frames. But a port will
transmit out (forward) a broadcast frame only if it has not exceeded the
maximum number of broadcast frames it can transmit.

Here’s an example. Let’s assume you set the timer interval for 10 and 100
Mbps ports to 100 milliseconds and the maximum broadcast frame limit
for a particular 100 Mbps port on the switch to 200 broadcast frames. At
these settings, the port will forward (transmit out) up to 200 broadcast
frames every 100 milliseconds. If the maximum is exceeded during the
specified time interval, the port discards any additional broadcast frames
and does not forward them.

Note
The AT-S39 default setting is no Broadcast Storm Control on the
switch.
