6.10 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.
Note: To use the mobility feature with this VNS, you must select the Enable
Multicast Support checkbox for the data port.
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.
Note: 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 page. For more information, see Section
3.2.4, “Setting up the data ports”, on page 42.
To enable multicast for a VNS:
1. From the main menu, click Virtual Network Configuration. The Virtual
Network Configuration page is displayed.
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.
