17 Broadcast Storm Control In Standalone mode, the broadcast storm control feature is enabled by default on all ports, and disabled on a port when an iSCSI storage device is detected. Broadcast storm control is re-enabled as soon as the connection with an iSCSI device ends. Broadcast traffic on Layer 2 interfaces is limited or suppressed during a broadcast storm. You can view the status of a broadcast-storm control operation by using the show io-aggregator broadcast storm-control status command. You can disable broadcast storm control by using the no ioaggregator broadcast storm-control command. Dell Networking OS Behavior: If broadcast traffic exceeds 1000 Mbps, the Aggregator limits it to 1000 Mbps per port-pipe. Disabling Broadcast Storm Control To disable broadcast storm control on an Aggregator, use the no io-aggregator broadcast stormcontrol command from CONFIGURATION mode. To re-enable broadcast storm control, enter the io-aggregator broadcast storm-control command. Displaying Broadcast-Storm Control Status To display the status of a current storm control operation, use the show io-aggregator broadcast storm-control status command from EXEC Privilege mode. Configuring Storm Control The following configurations are available only in PMUX mode. 1. To configure the percentage of broadcast traffic allowed on an interface, use the storm-control broadcast [packets_per_second in] command from INTERFACE mode. 2. To configure the percentage of multicast traffic allowed on an interface, use the storm-control multicast [packets_per_second in] command from INTERFACE mode. 3. To configure the percentage of unknown-unicast traffic allowed on an interface, use the storm- control unknown-unicast [packets_per_second in] command from INTERFACE mode. Broadcast Storm Control 199
