Configuring the GPON FTTH Layer 2 Multicast Service on the NMS
This topic describes how to configure the multicast service when an ONT is connected to an OLT through a GPON port.
Networking
The ONT is connected to the OLT in Layer 2 mode.
The OLT uses IGMP proxy, which is a Layer 2 multicast protocol.
The IGMP version of the multicast VLAN is IGMPv2.
The multicast programs are obtained in the dynamic mode.

Procedure
After all profiles are configured, perform the following steps to issue them to the device:
In the information list, right-click the record and choose Download to NE from the shortcut menu.
In the dialog box that is displayed, select the required NE(s), and click OK.
Configure a DBA profile.
Configure a line profile.
In a line profile, a GEM port can be bound to up to eight service streams. In a GEM port, different GEM connections need to be set up for different service streams.
In this example, the mapping between GEM ports and ONT-side services is implemented through VLANs, and the service streams of each service are mapped to GEM port 13. In addition, different GEM connections are set up for the management VLAN and the VLANs for the Internet, voice, and multicast services.
Configure a service profile.
Configure a VLAN translation policy for the ONT ETH port. Assume that the ONT connects to the HGW through ETH port 2. Configure a VLAN translation policy to make the ONT transparently transmit the MVLAN of the HGW in the upstream direction, and replicate multicast packets with the MVLAN unchanged in the downstream direction.
Configure an MEF IP traffic profile.
The profile name is ftth_iptv, CIR is off, priority is 4, and priority-based scheduling policy is Local-Setting. Traffic is scheduled based on the priority specified in the profile.
Configure an S-VLAN on the OLT side.
The prerequisite for performing operations in the navigation tree is to navigate to the NE Explorer of the OLT. To navigate to the NE Explorer of the OLT, do as follows: In the Main Topology, double-click the required OLT in the Physical Root navigation tree; or right-click the required OLT and choose NE Explorer from the shortcut menu.
The S-VLAN is used for the multicast service.
Provision services.

To navigate to the NE Explorer of the OLT, do as follows: In the Main Topology, double-click the required OLT in the Physical Root navigation tree; or right-click the required OLT and choose NE Explorer from the shortcut menu.
Add an ONT.
The ONT connects to the GPON port 0/1/0 is ONT 1. The serial number of the ONT is 32303131D659FD40, password is 0100000001, discovery mode for password authentication is Always On, management mode is OMCI, bound ONT line profile name is ftth, and the ONT service profile name is ftth.
HG8245H is used as an example. For other ONTs, set Terminal Type based on practical conditions.
The ONT software version is the same (V300R019C00&V500R019C00) for the SIP protocol and H.248 protocol.
Configure Ethernet port attributes and service channels of a GPON ONU.
Add a service virtual port on the OLT side.
Add a multicast VLAN on the OLT side.
Program match mode can be set when IGMP Work Mode is tv_off. The values of Program match mode are as follows:
After Configuration, IGMP Work Mode should be set to Proxy again, otherwise IGMP work abnormally.
Add a virtual multicast upstream port on the OLT side.
Configure a multicast user on the OLT side.
Result
The user can watch programs on TV.
Configuring the GPON FTTH Layer 3 Bridge Multicast Service on the NMS
This topic describes how to configure the multicast service when an ONT is connected to an OLT through a GPON port.
Networking
The ONT is connected to the OLT in Layer 3 bridge mode.
The ONT uses the IGMP snooping multicast protocol.
The OLT uses IGMP proxy, which is a Layer 2 multicast protocol.
The IGMP version of the multicast VLAN is IGMPv2.
Multicast programs are obtained dynamically.

Set the port capability set to adaptive. Then, the system adapts the port capability set of an online ONT to its actual capability.
Configure an MEF IP traffic profile.
The profile name is ftth_iptv, CIR is off, priority is 4, and priority-based scheduling policy is Local-Setting. Traffic is scheduled based on the priority specified in the profile.

Add a virtual multicast upstream port on the OLT side.
Configure a multicast user on the OLT side.
Configure a general VAS profile for the ONT.
To bind a WAN port to multiple LAN ports, set Physical Port Name to LAN1, ..., LANx. For example, to bind WAN 1 to LAN 1 and LAN 2, set Physical Port Name to LAN1, LAN2.
Bind a general VAS profile.
