The Forward All page configures the ports and/or LAGs that are to receive Multicast streams
from a specific VLAN. This feature requires that Bridge Multicast filtering in the
Address Properties page be enabled. If it is disabled, then all Multicast traffic is flooded to
ports in the device.
You can statically (manually) configure a port to Forward All, if the devices connecting to the
port do not support IGMP and/or MLD.
Multicast packets, excluding IGMP and MLD messages, are always forwarded to ports that
are defined as Forward All. The configuration affects only the ports that are members of the
selected VLAN.
To define Forward All Multicast:
Click Multicast > Forward All.
Define the following:
• VLAN ID equals to—The VLAN ID the ports/LAGs are to be displayed.
• Interface Type equals to—Define whether to display ports or LAGs.
Click Go. The status of all ports/LAGs are displayed.
Select the port/LAG that is to be defined as Forward All by using the following methods:
• Static—The port receives all Multicast streams.
• Forbidden—Ports cannot receive any Multicast streams, even if IGMP/MLD snooping
designated the port to join a Multicast group.
• None—The port is not currently a Forward All port.
Click Apply. The Running Configuration file is updated.
This feature can be used to ensure that the customer receives only the Multicast groups
requested (registered) and not others that may be transmitted in the network (unregistered).
Unregistered Multicast frames are usually forwarded to all ports on the VLAN.
You can select a port to receive or reject (filter) unregistered Multicast streams. The
configuration is valid for any VLAN of which the port is a member (or will be a member).
