Broadcast Storm Control
The Switch 1005 automatically creates an
alarm on each of its ports to monitor the level of broadcast traffic on
each port. The Broadcast Storm Control fields allow you to specify
thresholds for the level of broadcast traffic on a port. In addition, you
can specify an action to take place if the threshold is exceeded.
Rising Threshold%
The value entered here is the percentage
bandwidth of traffic using a broadcast address that will be reached
before you are notified. The default is 20%.
Falling Threshold%
The value entered here is the percentage
bandwidth of traffic using a broadcast address at which the alarm
trigger will be reset. This prevents the rising threshold events being
triggered continuously. The default is 10%.
Rising Action
none / event / disable port / disable port/notify / blip / blip
