M4300 Intelligent Edge Series Fully Managed Stackable Switches 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 on IGMP snooping queriers on the network and, separately, on VLANs.
