The storm control feature allows you to control unknown unicast, multicast, and broadcast traffic on Layer 2 and Layer 3 physical interfaces. OS10 device monitors the current level of traffic rate at fixed intervals, compares the traffic rate with configured levels, and drops excess traffic. By default, storm control is disabled on all interfaces. You can enable storm control using the storm-control { broadcast | multicast | unknown-unicast } rate-in-pps command in the INTERFACE mode. Configure storm control • The following example enables broadcast storm control with a rate of 1000 packets per second (pps) on Ethernet 1/1/1. OS10(conf-if-eth1/1/1)# storm-control broadcast 1000 QoS commands bandwidth Assigns a percentage of weight to the queue. Syntax bandwidth percent value Parameters percent value - Enter the percentage assignment of bandwidth to the queue (1 to 100). Default Not configured Command Mode POLICY-MAP QUEUE Usage Information If you configure this command, you cannot use the priority command for the class.
