ONFIGURING
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 will stop forwarding multicast to the port where the end device is
located.
These pages enable you to configure and display information on IGMP snooping queriers on the network and, separately,
on VLANs.
