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 2-113. 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

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
