Layer 2 IGMP (Snooping and Query) 28

Specifying Static Interfaces for 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.

•Unit – Stack unit. (Range: Always 1)

•Port or Trunk – Specifies the interface attached to a multicast router.

Web – Click IGMP Snooping, Static Multicast Router Port Configuration. Specify the interfaces attached to a multicast router, indicate the VLAN which will forward all the corresponding multicast traffic, and then click Add. After you have finished adding interfaces to the list, click Apply.

CLI – This example configures port 11 as a multicast router port within VLAN 1.
