Figure 4-1 Configure MVR Globally
Follow these steps to configure MVR globally:
1)  Enable MVR globally and configure the global parameters.
MVR Enable or disable MVR globally.
MVR Mode Specify the MVR mode as compatible or dynamic.
Compatible: In this mode, the switch does not forward report or leave 
messages from the hosts to the IGMP querier. This means IGMP querier cannot 
learn the multicast groups’ membership information from the switch. The IGMP 
querier must be statically configured to transmit all the required multicast 
streams to the switch via the multicast VLAN.
Dynamic: In this mode, after receiving report or leave messages from the hosts, 
the switch will forward them to the IGMP querier via the multicast VLAN (with 
appropriate translation of the VLAN ID). The IGMP querier can learn the multicast 
groups’ membership information through the report and leave messages, and 
transmit the multicast streams to the switch via the multicast VLAN according 
to the multicast forwarding table.
Multicast VLAN ID Specify an existing 802.1Q VLAN as the multicast VLAN.
Query Response
