To configure a specific VLAN click on the VLAN ID number access the advanced IGMP configuration screen.
The following example shows the IGMP information for VLAN1.
Multicast switches send IGMP host-query messages to discover which multicast groups are present on attached networks. These messages are sent to the all-systems group address of 224.0.0.1 with a time-to-live (TTL) value of 1.
Multicast switches continue to periodically send host-query messages to refresh their knowledge of memberships present on their networks. If, after some number of queries, the switch software discovers that no local hosts are members of a multicast group, the software stops forwarding onto the local network multicast packets from remote origins for that group and sends a prune message upstream toward the source.
To enable or disable and to set the query intervals follow these steps.
1.Select enable or disable from the drop down menu
2.Enter the desired query interval (10-200)
