Layer 2 multicast entries and usage of S series switches

For an S series switch, entries fall into protocol and forwarding entries. Protocol entries include router port entries and host port entries.
You can run the display igmp-snooping router-port command to check router port entries, run the display igmp-snooping port-info command to check host port entries, and run the display l2-multicast forwarding-table command to check forwarding entries. Protocol entries are triggered by protocol packets or manually generated. They are used to identify the protocol exchange status. Forwarding entries are generated based on protocol entries and are used to guide subsequent multicast data forwarding.
