Retype the new community name.3.13 CONFIGURING BROADCAST/MULTICAST STORMPROTECTIONThe ELS100-16TX provides automatic protection againstbroadcast/multicast storms. Multicast storms are excessivebroadcasts to all ports, typically caused by a malfunctioningdevice. They can result in severe network performance problems,including causing the network to crash.To protect against broadcast/multicast storms, you must define anacceptable rate for multicast traffic across a port. In many ways,this feature is similar to filtering.Each ELS100-16TX port can be individually configured forautomatic multicast storm protection. You define what level ofmulticasts the ELS100-16TX will recognize as a multicast storm byspecifying the number of multicast packets that can be transmittedwithin a given time period.For example, if you configure ELS100-16TX to transmit onto Port 3no more than five multicasts per 60 seconds, any multicastsdestined for Port 3 are discarded after the first five multicasts.After 60 seconds have elapsed, another five multicasts to Port 3will be allowed. This maintains an effective maximum rate of fivemulticast packets per minute.Note: LCM does not allow you to configure for multicast stormprotection. You must use an SNMP-based NMS. See thedocumentation that came with your NMS for configurationinstructions.
