MULTICAST FILTERING

Assigning Ports to Multicast Services

Multicast filtering can be dynamically configured using IGMP Snooping and IGMP Query messages as described in “Configuring IGMP Snooping Parameters” on page 3-137.For certain applications 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 an interface in a 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/ switch.

Web – Click IGMP Snooping, IGMP Member Port Table. Specify the interface attached to a multicast service (via an IGMP-enabled switch or multicast router), indicate the VLAN that will propagate the multicast service, specify the multicast IP address, and click Add. After you have completed adding ports to the member list, click Apply.
