Virtual Network configuration
Enabling multicast for a VNS
7.7 Enabling multicast for a VNS
A mechanism that supports multicast traffic can be enabled as part of a VNS definition. This 
mechanism is provided to support the demands of VoIP and IPTV network traffic, while still 
providing the network access control.
Define a list of multicast groups whose traffic is allowed to be forwarded to and from the VNS. 
The default behavior is to drop the packets. For each group defined, you can enable Multicast 
Replication by group.
To enable multicast for a VNS:
1. From the main menu, click Virtual Network Configuration. The Virtual Network 
Configuration screen appears.
2. In the left pane Virtual Networks list, click the VNS you want to enable Multicast for. The 
Topology tab is displayed.
3. Click the Multicast tab.

Before enabling multicast filters and depending on the topology of the VNS, you may 
need to define which physical interface to use for multicast relay. Define the multicast 
port on the IP Addresses screen of the Wireless Controller Configuration tab. For 
more information, see Section 4.2.4, “Setting up the data ports”, on page 53.
