Storm Control

Storm Control

Storm control prevents broadcast storms caused by broadcast packets, multicast packets, and unknown unicast packets.

Storm control is configured in the interface view to limit the number of packets per second.

In a detection interval, a device with storm control configured monitors the average rates of incoming packets on an interface and compares the average rates with the thresholds. When the rate of a particular type of packets exceeds the threshold allowed for these packets, the device performs storm control and takes a preconfigured storm control action to shut down the interface.

You can manually enable the shutdown interface or configure automatic recovery for the interface.
