@jeff - Thank you for your question. Storm control, by default, is disabled in all AOS switches. However, storm control can be enabled and configured to either drop traffic or shutdown the port depending on the AOS device in use. Below is a list of NetVanta switches and their storm control capabilties:
NetVanta Switch Platform | Types of Traffic Storm Control Available
| Available Action Options
|
|---|
| NetVanta 1224/1335/1534/1544/1638/2nd Gen 123x | Unicast, Multicast, Broadcast | Drop packets OR Shutdown port |
| NetVanta 1524 | Multicast, Broadcast | Drop packets |
| 1st Gen 123x/31xx/3448/3458/344 | Unicast, Multicast, Broadcast | Drop packets |
Storm control can be configured in the command line interface in switchport configuration mode. The commands below show the syntax to configure storm-control. The rising and falling threshold levels are specified by percentages:
storm-control broadcast level <rising level>
storm-control broadcast level <rising level> <falling level>
storm-control multicast level <rising level>
storm-control multicast level <rising level> <falling level>
storm-control unicast level <rising level>
storm-control unicast level <rising level> <falling level>
Also, below is the syntax to configure the switchport to shutdown (if the AOS switch allows it) should the threshold be exceeded:
storm-control action shutdown
Storm control can also be configured in the web interface by navigating to the "Storm Control" webpage under 'Data' on the navigation panel on the left.
Please do not hesitate to let us know if you have any further questions.
Thanks,
Noor
