M4100 Series Managed Switch
• Forward Unregistered: If a packet is received from a VLAN with a multicast
destination address and no ports in the VLAN are registered to receive multicast
packets for that address, then the packet is flooded to all ports in the VLAN. The
responsibility for accepting or dropping the packets belongs to the hosts. If a multicast
packet is received and there are ports registered to receive it, the packet is sent only
to the registered ports.
• Forward All: All multicast packets received from a VLAN are flooded to all ports in the
VLAN, regardless of port registrations to multicast addresses.
• Filter Unregistered: If a packet is received from a VLAN for a multicast destination
address and no ports in the VLAN are registered to receive multicast packets for that
address, then the packets are dropped.
The default value is Forward Unregistered.
