until the storm has subsided. This method can be utilized by selecting the
Drop option of the Action field in the window
below.
The Switch will also scan and monitor packets coming into the Switch by monitoring the Switch’s chip counter. This
method is only viable for Broadcast and Multicast storms because the chip only has counters for these two types of
packets. Once a storm has been detected (that is, once the packet threshold set below has been exceeded), the
Switch will shutdown the port to all incoming traffic with the exception of STP BPDU packets, for a time period
specified using the CountDown field. If the packet storm discontinues before the Countdown timer expires, the port will
again allow all incoming traffic. If this field times out and the packet storm continues, the port will be placed in a
Shutdown Forever mode which will produce a warning message to be sent to the Trap Receiver. Once in Shutdown
Forever mode, the port will be recovered after 5 minutes, or the user manually resets the port using the

window in the
Administration
folder and selecting the disabled port and returning it to an Enabled
status. To utilize this method of Storm Control, choose the Shutdown option of the Action field in the window below.
