Storm Control Threshold
Settings
N/A Set the threshold values for the broadcast, unicast,
and multicast traffic for each port. The number of
packets being sent is compared against the
threshold value. If an undesirable network event
occurs and the threshold value has been exceeded,
a yes value is displayed in the appropriate column
in the Port Status tab and in the Traffic Exceeded
on Any Port parameter in the Switch for
Automation Status tab. Network traffic of the type
that exceeded threshold (broadcast, unicast, or
multicast) will be dropped until it falls below the
falling threshold. The falling threshold is
automatically set to 5% less then the entered
threshold value.
