•For the MDU V800R305, the IGMP packet processing mode is configured in BTV mode. By default, the IGMP packet processing mode is set to snooping. That is, an IGMP packet is captured to the CPU by default. If the corresponding port is not added to the MVLAN, the system discards the IGMP packet.
In BTV mode, you can run the display igmp config global command to view the configuration status of the IGMP packet processing mode.
•For the MDU V800R306 or a later version, the IGMP packet processing mode of the MDU V800R305 is configured in MVLAN mode. By default, no MVLAN exists. That is, IGMP packets are not captured to the CPU. When an MVLAN is created, the default IGMP packet processing mode is off.
In MVLAN mode, you can run the display igmp config vlan command to view the configuration status of the IGMP packet processing mode.
