Multicast Global Parameters - Dell PowerConnect 5316M User Manual

When IGMP snooping is enabled globally, the switching ASIC is programmed to forward all IGMP
packets to the CPU. The CPU analyzes the incoming packets and determines which ports are to
join which Multicast groups, which ports have Multicast routers generating IGMP queries, and
what routing protocols are forwarding packets and Multicast traffic. Ports requesting to join a
specific Multicast group issue an IGMP report specifying that Multicast group. This results in the
creation of the Multicast filtering database.
The Multicast Global Parameters page contains fields for enabling IGMP Snooping on the switch
module. To open the Multicast Global Parameters page, click Switch→ Multicast Support→
Global Parameters in the tree view.
