IGMP Snooping Querier 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 multicasts 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. The IGMP Snooping Querier feature contains links to the following pages: • IGMP Snooping Querier Configuration on page 112 • IGMP Snooping Querier VLAN Configuration on page 113 • IGMP Snooping Querier VLAN Status on page 114 IGMP Snooping Querier Configuration Use this page to enable or disable the IGMP Snooping Querier feature, specify the IP address of the router to perform the querying, and configure the related parameters.
