1.11 CISC-L2-000160

Information

The Cisco switch must have Storm Control configured on all host-facing switchports.

GROUP ID: V-220636RULE ID: SV-220636r648763

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 g0/2 - 8SW1(config-if-range)#storm-control unicast bps 62000000SW1(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.
