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 for IGMP snooping queriers on the network
and, separately, on VLANs.
