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 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.
Review the configuration for the desired storm control settings on host-facing ports. ! interface ethernet 1/1/5 broadcast limit 8787 multicast limit 777 unknown-unicast limit 888 ! If host facing ports are not configured for storm control protection, this is a finding.
Configure storm control on each host-facing switch ports. 1. Enter global configuration mode: device#configure terminal 2. Configure storm control: device (config-if-e2500-1/1/5)#broadcast limit 8787 device (config-if-e2500-1/1/5)#multicast limit 777 device (config-if-e2500-1/1/5)#unknown-unicast limit 888
