25.1.7 Multicast VLAN
IGMP (Internet Group Management Protocol) is a network-layer protocol used to establish
membership in a multicast group - it is not used to carry user data. Multicast VLAN is designed for
applications (such as Media-on-Demand (MoD)) using multicast traffic across an Ethernet ringbased
service provider network. Multicast VLAN allows one single multicast VLAN to be shared among
different subscriber VLANs on the network. This improves bandwidth utilization by reducing
multicast traffic in the subscriber VLANs and simplifies multicast group management.
• Multicast VLAN (MVLAN) applies only to downstream multicast stream and IGMP or Multicast
Listener Discovery (MLD) packets. The IES forwards upstream IGMP packets according to the
unicast VLAN modes the UNI port has joined.
• MVLAN must co-work with one of the 4 VLAN modes - VLAN tagging and trunk, stacking VLAN
tagging and trunk, VLAN translation and aggregation, or stacking VLAN translation and
aggregation.
• A UNI port must join one of the 4 VLAN modes before it can join a MVLAN. The UNI VLAN in the
joined VLAN modes and MVLAN must be the same.
• Add the ATM VC to MVLAN (see
).
25.1.8 Management and VoIP VLAN
• The management VLAN and VoIP VLAN both accept only single tagged packets on both the NNI
and CPU ports.
• UNI ports cannot communicate with the CPU port.
