This example displays all the known multicast services supported on VLAN 1, along with the ports
propagating the corresponding services. The Type field shows if this entry was learned dynamically or was
statically configured.

12.1.5 Assigning Ports to Multicast Services
Multicast filtering can be dynamically configured using IGMP Snooping and IGMP Query messages as
described in section 12.1.1 Configuring IGMP Snooping and Query Parameters. 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.
Follow these guidelines.
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.
Configuring the Switch Using the Web or CLI
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.
