Configuring IGMP Snooping Querier

Use this page to configure the global IGMP snooping querier settings on the device. 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. When Layer-3 IP multicast routing protocols
are enabled in a network with IP multicast routing, the IP multicast router acts as the IGMP querier. However,
if the IP-multicast traffic in a VLAN needs to be Layer-2 switched only, an IP-multicast router is not required.
The IGMP snooping querier can perform the IGMP snooping functions on the VLAN.

IGMP Snooping Querier Configuration Fields
Description
The administrative mode for the IGMP snooping querier on the device. When set to Enable, the
IGMP snooping querier sends out periodic IGMP queries that trigger IGMP report messages from the
switches that want to receive IP multicast traffic. The IGMP snooping feature listens to these IGMP
reports to establish appropriate forwarding.
The snooping querier address to be used as source address in periodic IGMP queries. This address is
used when no IP address is configured on the VLAN on which the query is being sent.
The IGMP protocol version used in periodic IGMP queries.
The amount of time the IGMP snooping querier on the device should wait between sending periodic
IGMP queries.
The amount of time the device remains in non-querier mode after it has discovered that there is a
multicast querier in the network.
