390 Multicast Support
Unregistered Multicast
Multicast frames are generally forwarded to all ports in the VLAN. If IGMP
Snooping is enabled, the device learns about the existence of Multicast
groups and tracks which ports have joined what Multicast group.
Multicast groups can also be statically enabled. This enables the device to
forward the Multicast frames (from a registered Multicast group) only to
ports that are registered to that Multicast group.
Traffic from unregistered Multicast groups, which are the groups that are not
known to the device, can either be filtered or forwarded. After a port has been
set to Forwarding/Filtering, its configuration is valid for any VLAN of which it
is a member (or will be a member of).
To set the action for unregistered Multicast groups on a port or LAG:
1
Click Switching > Multicast Support > Unregistered Multicast in the
tree view to display the
Unregistered Multicast: Summary page.
The action for each port is displayed.
2 To modify the forwarding action for an interface, click Edit, and enter the
fields.
•
Interface — Select a port or LAG.
•
Unregistered Multicast — Select the forwarding status of the selected
interface. The possible options are:
•
Forwarding — Enables forwarding of unregistered Multicast
frames on the selected port or port-channel.
•

the selected VLAN interface.
