4.7.2.5 IGMP Router Setting
Depending on your network connections, IGMP snooping may not always be able to locate the IGMP querier. Therefore, if the
IGMP querier is a known multicast router/ switch connected over the network to an interface (port or trunk) on your PoE
Managed Switch, you can manually configure the interface (and a specified VLAN) to join all the current multicast groups
supported by the attached router. This can ensure that multicast traffic is passed to all the appropriate interfaces within the PoE
Managed Switch. The IGMP Router Setting and Status screens in Figure 4-7-15 & Figure 4-7-16 appear.
