Specifying Interfaces Attached to a Multicast Router

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 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 switch.

Command Attributes

•Interface – Activates the Port or Trunk scroll down list.

•VLAN ID – Selects the VLAN to propagate all multicast traffic coming from the attached multicast router/switch.
