How to Configure IGMP Snooping and MVR
Enabling or Disabling IGMP Snooping on a Switch
When IGMP snooping is globally enabled or disabled, it is also enabled or disabled in all existing VLAN
interfaces. IGMP snooping is enabled on all VLANs by default, but can be enabled and disabled on a per-VLAN
basis.
Global IGMP snooping overrides the VLAN IGMP snooping. If global snooping is disabled, you cannot
enable VLAN snooping. If global snooping is enabled, you can enable or disable VLAN snooping.
