Only if the multicast function is enabled can the multicast-related configurations 
take effect.
Enabling IGMP on an 
Interface
This configuration task is to enable IGMP on the interface which needs to maintain 
the multicast membership. After this, you can initiate IGMP feature configuration.
Perform the following configuration in interface view.
By default, IGMP is disabled on the interface.
CAUTION:
If the VLAN VPN is enabled on a port, the IGMP Snooping feature cannot be 
enabled on the VLAN for the port, and the IGMP feature cannot be enabled on 
the corresponding interface either.
If IGMP Snooping feature is enabled on a VLAN, or IGMP is enabled on the 
interface, you cannot add the member port on which VLAN VPN is enabled 
into the VLAN.
Enabling Compatibility 
Control Function of the 
Switch
With the compatibility control function enabled the switch processes the protocol 
message with the destination IP address 224.0.0.1 in the IGMP Report packet. 
Otherwise, the switch discards this kind of packets.
Perform the following configuration in system view.
