Discussion

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.

Check Content

Review the switch configuration to verify that storm control is enabled on host-facing interfaces.
 
If storm control is not enabled on all host-facing switch ports, this is a finding.

Fix Text

Configure storm control on each host-facing switch ports.
