GS752TXS and GS728TXS Smart Switches Bridge Multicast Forwarding When you create a VLAN, a default multicast forwarding option is assigned. You can use the Global Multicast Mode setting to set all VLANs currently configured on the switch to a selected forwarding mode. The global setting does not create a default setting for VLANs created subsequently-it simply ensures that all existing VLANs are configured with the specified mode. You can also configure how the switch forwards multicast packets on an individual or per-VLAN basis.  To configure bridge multicast forwarding: 1. Select Switching Multicast  MFDB  Bridge Multicast Forwarding. 2. Select the VLAN for which the Forwarding Mode is to be changed. 3. From the Forwarding Mode menu, select the forwarding mode: • 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. 4.

Bridge Multicast Forwarding
When you create a VLAN, a default multicast forwarding option is assigned. You can use the
Global Multicast Mode setting to set all VLANs currently configured on the switch to a
selected forwarding mode. The global setting does not create a default setting for VLANs
created subsequently—it simply ensures that all existing VLANs are configured with the
specified mode. You can also configure how the switch forwards multicast packets on an
individual or per-VLAN basis.
To configure bridge multicast forwarding:
1.
Select
Switching
Multicast
MFDB
Bridge Multicast Forwarding
.
2.
Select the VLAN for which the Forwarding Mode is to be changed.
3.
From the Forwarding Mode menu, select the forwarding mode:
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.
