3.13CONFIGURING BROADCAST/MULTICAST STORM PROTECTION
The ELS100-16TX provides automatic protection against broadcast/multicast storms. Multicast storms are excessive broadcasts to all ports, typically caused by a malfunctioning device. They can result in severe network performance problems, including causing the network to crash.
To protect against broadcast/multicast storms, you must define an acceptable rate for multicast traffic across a port. In many ways, this feature is similar to filtering.
Each ELS100-16TX port can be individually configured for automatic multicast storm protection. You define what level of multicasts the ELS100-16TX will recognize as a multicast storm by specifying the number of multicast packets that can be transmitted within a given time period.
Note: LCM does not allow you to configure for multicast storm protection. You must use an SNMP-based NMS. See the documentation that came with your NMS for configuration instructions.
For example, if you configure ELS100-16TX to transmit onto Port 3 no more than five multicasts per 60 seconds, any multicasts destined for Port 3 are discarded after the first five multicasts. After 60 seconds have elapsed, another five multicasts to Port 3 will be allowed. This maintains an effective maximum rate of five multicast packets per minute.
