Which ports want to join which Multicast groups.

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 is accepting members. This results in the creation of the Multicast filtering database.
The IGMP Snooping page contains the following fields:

Host Timeout. Indicates the amount of time host waits to receive a message before timing out. The default time is 260 seconds.
MRouter Timeout. Indicates the amount of the time the Multicast router waits to receive a message before it times out. The default value is 300 seconds.
Leave Timeout. Indicates the amount of time the host waits, after requesting to leave the IGMP group and not receiving a Join message from another station, before timing out. If a Leave Timeout occurs, the Switch notifies the Multicast device to stop sending traffic The Leave Timeout value is either
