packets coming into the Switch 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 Rest
mode which will produce a warning message recorded in the log. Once in Shutdown Rest mode, the
port will be recovered after 5 minutes, or the user manually resets the port using the Port
Configuration window in the Configuration 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.
