Port-Based Traffic Control Configuration Examples This section contains the following examples: • Configuring Multiple Traffic Control Features • Configuring PFC (PCM8024-k Only) Configuring Multiple Traffic Control Features The commands in this example configure storm control, LLPF, and protected port settings for various interfaces on the switch. The storm control configuration in this example sets thresholds on the switch so that if broadcast traffic occupies more than 10% on the bandwidth on any physical port, the interface blocks the broadcast traffic until the measured amount of this traffic drops below the threshold. The LLPF configuration in this example disables all PAgP and VTP PDUs from being forwarded on any switch port or LAG. The protected port configuration in this example prevents the clients connected to ports 3, 4, and 9 from being able to communicate with each other. To configure the switch: 1 Configure storm control for broadcast traffic on all physical interfaces. console(config)#interface range gi1/0/1-24 console(config-if)#storm-control broadcast level 10 2 Configure LLPF to block PAgP and VTP PDUs on all physical interfaces. console(config-if)#service-acl blockpagp blockvtp console(config-if)#exit 3 Specify a name for protected port group 0. console(config)#protected 0 name clients 4 Add the ports to the protected port group. console(config)#interface gi1/0/3 console(config-if-Gi1/0/3)#switchport protected 0 console(config-if-Gi1/0/3)#exit 710 Configuring Port-Based Traffic Control
