Displaying And Maintaining An Ethernet Interface - HP 4800G Series Configuration Manual

To do...
Specify to send log when the
traffic detected exceeds the
upper threshold or drops down
below the lower threshold from
a point higher than the upper
threshold
For network stability sake, configure the interval for generating traffic statistics to a value that is not
shorter than the default.
The storm constrain function, after being enabled, requires a complete statistical period (specified
by the storm-constrain interval command) to collect traffic data, and analyzes the data in the next
period. Thus, it is normal that a period longer than one statistic period is waited for a control action
to happen if you enable the function while the packet storm is present. However, the action will be
taken within two periods.
The storm constrain function is applicable to multicast packets, and broadcast packets; and you
can specify the upper and lower threshold for any of the three types of packets.

Remarks
Optional
By default, the system sends
log when the traffic detected
exceeds the upper threshold or
drops down below the lower
threshold from a point higher
than the upper threshold.
