This switch can passively snoop on IGMP Query and Report packets
transferred between IP multicast routers/switches and IP multicast host
groups to identify the IP multicast group members. It simply monitors the
IGMP packets passing through it, picks out the group registration
information, and configures the multicast filters accordingly.

When IGMP snooping is enabled globally, the per VLAN interface settings
for IGMP snooping take precedence. When IGMP snooping is disabled
globally, snooping can still be configured per VLAN interface, but the
interface settings will not take effect until snooping is re-enabled globally.
