The multicast route statistics feature provides statistics for multicast streams through the switch. Using the Command Line Interface (CLI), Simple Network Management Protocol (SNMP) or Enterprise Device Manager (EDM), you can track the number of senders sending multicast streams to a particular group address. You can also obtain a count of the packets or bytes being received for a particular multicast group address and the average size of the frames. Multicast route statistics are supported for both IPv4 and IPv6 group addresses.

Determining the route statistics is especially useful when debugging a multicast network and also when administering the network.

Multicast route statistics and DvR

When you enable or clear IP multicast route statistics on the Controller node of a DvR domain, the configuration is automatically pushed to the Leaf nodes within the domain.

For more information on DvR, see Distributed Virtual Routing Fundamentals.
