Defining Multicast TV VLAN
An access port can be configured as a member of a Multicast TV VLAN. See
Defining VLAN Interface Setting . This is required to supply multicast transmissions
to Level 2-isolated subscribers, without replicating the multicast transmissions for
each subscriber VLAN. IGMP snooping is supported for those transmissions.
Any VLAN can be 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 “Defining VLAN Interface Settings”).
The Multicast TV VLAN configuration is defined per port. Customer ports are
configured to be member of Multicast TV VLAN using the
Multicast TV VLAN
Page.
