If enabled, the switch forwards IGMP Join/Leave PDUs that it receives on a downstream
port to an upstream mrouter interface. In addition, the switch forwards a multicast data
stream to an upstream mrouter interface only if that port already received an IGMPv1 or

default is Enable.
If disabled, the switch forwards IGMP Join/Leave PDUs, known multicast streams, and
unknown multicast streams to the upstream mrouter interface.
