RackSwitch G8000 Application Guide

The switch supports the following IGMPv3 filter modes:

„INCLUDE mode: The host requests membership to a multicast group and provides a list of IP addresses from which it wants to receive traffic.

„EXCLUDE mode: The host requests membership to a multicast group and provides a list of IP addresses from which it does not want to receive traffic. This indicates that the host wants to receive traffic only from sources that are not part of the Exclude list. To disable snooping on EXCLUDE mode reports, use the following command:

RS G8000 (config)# no ip igmp snoop igmpv3 exclude

By default, the switch snoops the first eight sources listed in the IGMPv3 Group Record. Use the following command to change the number of snooping sources:

RS G8000 (config)# ip igmp snoop igmpv3 sources <1-64>

IGMPv3 Snooping is compatible with IGMPv1 and IGMPv2 Snooping. You can disable snooping on version 1 and version 2 reports, using the following command:

RS G8000 (config)# no ip igmp snoop igmpv3 v1v2
