Information

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.

Solution

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

SW1(config)#int range e0/2 - 8
SW1(config-if-range)# storm-control unicast level 50
SW1(config-if-range)# storm-control broadcast level 40
