VLAN Management : Access Port Multicast TV VLAN
 
Access Port Multicast TV VLAN
Multicast TV VLANs enable Multicast transmissions to subscribers who are not on the same data VLAN (Layer 2-isolated), without replicating the Multicast transmission frames for each subscriber VLAN.
Subscribers, who are not on the same data VLAN (Layer 2-isolated) and are connected to the device with different VLAN ID membership, can share the same Multicast stream by joining the ports to the same Multicast VLAN ID.
The network port, connected to the Multicast server, is statically configured as a member in the Multicast VLAN ID.
The network ports, which through subscribers communicate with the Multicast server (by sending IGMP messages), receive the Multicast streams from the Multicast server, while including the Multicast TV VLAN in the Multicast packet header. For this reasons, the network ports must be statically configured as the following:
Trunk or general port type (see Interface Settings)
Member of the Multicast TV VLAN
The subscriber receiver ports can be associated with the Multicast TV VLAN only if it is defined as an access port.
One or more IP Multicast address groups can be associated with the same Multicast TV VLAN.
Any VLAN can be configured as a Multicast-TV VLAN. A port assigned to a Multicast-TV VLAN:
Joins the Multicast-TV VLAN.
Packets passing through egress ports in the Multicast TV VLAN are untagged.
The port’s Frame Type parameter is set to Admit All, allowing untagged packets (see Interface Settings).
The Multicast TV VLAN configuration is defined per port. Customer ports are configured to be member of Multicast TV VLANs using the Port Multicast VLAN Membership page.
