3Configuring the SwitchSetting Multicast Storm ThresholdsYou can protect your network from excess multicast traffic by setting thresholds foreach port. Any multicast packets exceeding the specified threshold will then bedropped.Command Usage• Multicast Storm Control is disabled by default.• Due to an ASIC chip limitation, the supported storm control modes include:- broadcast- broadcast + multicast- broadcast + multicast + unknown unicastThis means that when mulicast storm control is enabled, broadcast storm controlis also enabled (using the threshold value set by the multicast storm controlcommand). And when unknown unicast storm control is enabled, both broadcastand multicast storm control are also enabled (using the threshold value set by theunknown unicast storm control command).• The storm control feature provided on this configuration page is a hardware levelcontrol function. Traffic storms can also be controlled at the software level usingautomatic storm control which triggers various control responses. This control typeis only supported by the Command Line Interface as described under “AutomaticTraffic Control Commands” on page 4-237. However, note that only one of thesecontrol types can be applied to a port. Enabling hardware-level storm control on aport will disable automatic storm control on that port.Command Attributes• Port – Port number. (Range: 1-28/52)• Type – Indicates the port type. (100BASE-TX, 1000BASE-T, or SFP)• Protect Status – Enables or disables multicast storm control. (Default: Disabled)• Threshold – Threshold as percentage of port bandwidth. (Range: 64-100000kilobits per second for Fast Ethernet ports; 64-1000000 kilobits per second forGigabit ports; Default: 64 kilobits per second)• Trunk – Shows if port is a trunk member.3-174
