IGMP Snooping Configuration Notes for Layer 3 Devices

  • If Layer 3 multicast routing is enabled on an interface or VLAN, do not attempt to enable Layer 2 IGMP snooping on the same interface or VLAN.
  • If the "route-only" feature is enabled on the Layer 3 switch, then IP multicast traffic reduction will not be supported.
