Adding Multicast Addresses to VLANs

Multicast filtering can be dynamically configured using IGMP Snooping and IGMP Query messages as described in “Configuring IGMP Parameters” on page 2-72.For certain application that require tighter control, you may need to statically configure a multicast service on the switch. First add all the ports attached to participating hosts to a common VLAN, and then assign the multicast service to that VLAN group.

Command Usage

Static multicast addresses are never aged out.

When a multicast address is assigned to specific VLAN, the corresponding traffic can only be forwarded to ports within that VLAN.

Command Attribute

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.

Multicast IP – The IP address for a specific multicast service

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