Dell PowerConnect 3324 User Manual page 282

When IGMP snooping is globally enabled, the switching ASIC is programmed to forward
all IGMP frames to the CPU. The CPU analyzes the incoming frames and determines
which ports want to join which Multicast groups, which ports have Multicast routers
generating IGMP queries, and what Routing protocols are forwarding packets and Multicast
traffic. A port wishing to join a specific multicast group issues an IGMP report specifying
that multicast group.
The Multicast Global Parameters page allows network managers to enable IGMP Snooping
and Multicast Filtering in general on the device. To open the Multicast Global Parameters
page:
• Click Switch > Multicast Support > Global Parameters in the Tree View. The
Multicast Global Parameters page opens.
