IGMP (Internet Group Management Protocol) snooping filters allow you to configure a policy file on a port to allow or deny IGMP report and leave packets coming into the port. (For details on creating policy files, see Policy Manager.) The IGMP snooping filter feature is supported by IGMPv2 and IGMPv3.
Note
Do not confuse IGMP snooping filters with IGMP snooping hardware filters explained in previous section. IGMP snooping filters are software filters, and the action is applied at the software level by the ExtremeXOS multicast manager.For the policies used as IGMP snooping filters, all the entries should be IP address type entries, and the IP address of each entry must be in the class-D multicast address space but should not be in the multicast control subnet range (224.0.0.x/24).
