Storm control prevents LAN interfaces from being disrupted by a broadcast storm. A broadcast storm occurs when broadcast packets flood the subnet, creating excessive traffic and degrading network performance. Errors in the protocol-stack implementation or in the network configuration can cause a broadcast storm. About Storm Control.
Dec 23, 2019 Learn how to configure storm control on Catalyst 1000 switches using the storm-control interface configuration commands. Storm control prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on one of the physical interfaces. See examples, traffic patterns, and additional references for storm control feature history.

Sep 14, 2007 This chapter describes how to configure the traffic storm control feature on the Cisco 7600 series routers. Release 12.1 (12c)E1 and later releases support traffic storm control. For earlier releases, refer to "Configuring Broadcast Suppression."
Storm control (or traffic suppression) monitors packets passing from an interface to the switching bus and determines if the packet is unicast, multicast, or broadcast. The switch counts the number of packets of a specified type received within the 1-second time interval and compares the measurement with a predefined suppression-level threshold.
Understanding Traffic Storm Control. A traffic storm occurs when packets flood the LAN, creating excessive traffic and degrading network performance. The traffic storm control feature prevents LAN ports from being disrupted by a broadcast, multicast, or unicast traffic storm on physical interfaces.

Mar 1, 2019 Storm control, or traffic suppression, monitors packets passing from an interface to the switching bus and determines if the packet is unicast, multicast, or broadcast. The switch counts the number of packets of a specified type received within the one second time interval and compares the measurement with a pre-defined suppression-level threshold.
To protect ourselves against this, Cisco switches offer the storm-control feature. We can configure a threshold on interfaces to set a limit to the number of broadcast, multicast or unknown unicast traffic and an action when the threshold is exceeded. Heres an example how to configure this: SW1(config-if)#storm-control ?
