3.3.2.3 Configuring Multicast Services
Multicast filtering can be dynamically configured using IGMP Snooping and IGMP
Query messages as described in “Configuring IGMP Snooping Parameters” on
page 3-55. For certain applications that require tighter control, you might need to
manually assign a
multicast service to a specific interface. First add all the ports
connected to participating
hosts to a common VLAN, and then assign the multicast
service to that VLAN group.
Note the following points about configuring multicast services:
■ Static multicast addresses are never aged out.
■ When a multicast address is statically assigned to an interface in a specific VLAN,
the corresponding traffic can only be forwarded to ports in that VLAN.
When configuring multicast services through the web interface or CLI, the following
parameters are displayed or can be configured:
■ All known ports and Multicast Services supported on VLAN:
■ VLAN – The VLAN on the switch.
(The pull-down menu includes the VLAN ID and name.)
■ IP Address – The IP address for a specific multicast service.
■ Interface – The interfaces that are connected to multicast routers and whether
the assignment was static (User) or dynamic (IGMP).
■ Ports and Multicast Services statically configured on VLAN:
■ IP Address – The IP address for a specific multicast service.
■ Available Ports – The interfaces that have not been assigned to the selected
VLAN to support a specific multicast service.
■ Current Static Ports (IP Addresses) – The interfaces that have already been
assigned to the selected VLAN to propagate a specific multicast service.
Includes the IP address assigned to the interface.
Web Interface: Configuring Multicast Services
● Open Switch Config ⇒ Broadcast & Multicast ⇒ Multicast Support.
To display the switch interfaces that propagate a specific multicast service:
1. Select the VLAN ID and the IP address for a multicast service from the pull-down
menus.
2. Click Query.
To manually assign a multicast service to a specific interface:
1. Select the VLAN from the pull-down menu.
