1.6.7 (Optional) Setting Parameters of the IGMP Snooping Querier
Context
If IGMP messages sent from the upstream router cannot reach the S9300 for certain reasons, for
example, IGMP is not enabled or if the multicast forwarding entries on the upstream router are
statically configured and need not be dynamically learned, you can configure the IGMP snooping
querier on the S9300. The IGMP snooping querier then sends IGMP Query messages. You can
adjust parameters of the IGMP snooping querier as required.
