Displaying And Maintaining An Ethernet Interface - 3Com 4510G Configuration Manual

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.
