NETGEAR 24-Port Gigabit Smart Managed Pro Switch with PoE+ and 2 SFP Ports Model GS724TPv2 IGMP Snooping Querier Overview IGMP snooping requires that one central switch or router periodically query all end-devices on the network to announce their multicast memberships. This central device is the IGMP querier. The IGMP query responses, known as IGMP reports, keep the switch updated with the current multicast group membership on a port-by-port basis. If the switch does not receive updated membership information in a timely fashion, it stops forwarding multicasts to the port where the end device is located. You can configure and display information about IGMP snooping queriers on the network and, separately, on VLANs. Configure IGMP Snooping Querier You can configure the parameters for IGMP snooping querier. Only a user with read/write access privileges can change the data on this page.  To configure IGMP snooping querier settings: 1. Connect your computer to the same network as the switch.
