Configure an IGMP Snooping Querier

An IGMP snooping querier is a device that queries devices on the network for multicast
membership.
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.
