You can check the number of unicast, multicast, and broadcast packets passing through the switch by using the command "show port mac".
A traffic storm occurs when packets flood the LAN, creating excessive traffic and degrading network performance. Errors in the protocol-stack implementation or in the network configuration can cause a storm. Storm control can be implemented globally or on a per-port basis. Global storm control and per-port storm control cannot be enabled at the same time.
If you activated global storm control it prevents switchports on a LAN from being disrupted by a broadcast, multicast, or unicast storm on one of the interfaces. Global storm control monitors incoming traffic statistics over a time period and compares the measurement with a predefined suppression level threshold.
Else you activated Per-port storm control uses rising and falling thresholds to block and then restore the forwarding of broadcast, unicast, or multicast packets. You can also set the switch to shut down the port when the rising threshold is reached. And it is also control uses a bandwidth-based method to measure traffic activity.
