instructions on resetting.

Setting Broadcast Storm Control
The Switch 2000 TR automatically creates an alarm 
on each of its ports for monitoring broadcast levels if 
an alarm is set. This field allows you to set broadcast 
threshold levels on each port. You can also set the 
threshold action per port. Thresholds are calculated 
using a moving 20 second window.
Rising Threshold%
The Rising threshold percentage setting determines 
the amount of broadcast traffic that will be allowed 
before an alarm is sent. The default setting is 60%.
Falling Threshold%
The Falling threshold percentage setting determines 
the level at which the broadcast threshold will be 
reset. This setting prevents the rising threshold events 
from being triggered continuously. Events are only 
enabled after the Falling Threshold is met. The default 
setting is 50%.

Set the threshold fields by entering a number 
between 0 and 99.
