Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Storm control

Traffic storms created by packet flooding or other reasons may degrade the performance of the network. The storm control feature allows you to control unknown unicast, multicast, and broadcast traffic on L2 and L3 physical interfaces.

OS10 devices monitor the current level of the traffic rate at fixed intervals, compares the traffic rate with the configured levels, and drops excess traffic.

By default, storm control is disabled on all interfaces. Enable storm control using the storm-control { broadcast | multicast | unknown-unicast } rate-in-pps command in INTERFACE mode.

• Enable broadcast storm control with a rate of 1000 packets per second (pps) on Ethernet 1/1/1.
