Enabling Storm Control A broadcast storm is the result of an excessive amount of broadcast messages simultaneously transmitted across a network by a single port. Forwarded message responses can overload network resources and/or cause the network to time out. Your switch measures the incoming broadcast/multicast packet rate per port and discards packets when the rate exceeds the defined value. Storm control is enabled per device, by defining the packet type and the rate the packets are transmitted. Ports groups provide storm protection for an entire port group. Use the Storm Control page to enable and configure storm control. To open the Storm Control page, click Switch→Ports→Storm Control in the tree view. Figure 7-15. Storm Control Page Count Multicast with Broadcast - Enable counts Broadcast and Multicast traffic; Disable counts only Broadcast traffic. Port - The port from which storm control is enabled. Broadcast Control - Enables or disables forwarding unknown packet types on the device. Broadcast Rate Threshold - The maximum rate (kilobytes per second) at which unknown packets are forwarded. The range is 0-148,800. The default value is 12000. All values are rounded to the nearest 64Kbps. If the field value is under 64Kbps, the value is rounded up to 64Kbps.
