A traffic storm occurs when packets flood a LAN, creating excessive traffic and degrading network performance. Traffic storm control prevents network disruption by suppressing ingress traffic when the number of packets reaches a configured threshold levels.

Traffic storm control monitors ingress traffic levels on a port and drops traffic when the number of packets reaches the configured threshold level during any one-second interval.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.


Configure storm control for each host-facing interface as shown in the example below:

SW1(config)#int range g0/2 - 8
SW1(config-if-range)#storm-control unicast bps 62000000
SW1(config-if-range)#storm-control broadcast level bps 20000000

Note: The acceptable range is 10000000 -1000000000 for a gigabit Ethernet interface, and 100000000-10000000000 for a 10-gigabit interface. Storm control is not supported on most FastEthernet interfaces.
