Software User Manual 12/10/09 D-Link Unified Access System CONFIGURING IGMP SNOOPING QUERIERS 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. 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 related parameters. Users must have Read/Write access privileges to change the data on this page. To access this page, click LAN > L2 Features > IGMP Snooping Querier > Querier Configuration in the navigation tree.
