How to Configure 2 Multicast Vlan in order to watch IPTV through only one service-port

When we need  to configure two Multicast VLAN for IPTV service, that is to say, one VLAN to SD channels and another VLAN to HD channels, we have a problem, in service-port we can configure only one VLAN, so we can watch only SD or HD channels.

The following is BTV configuration in MA5603T

btv
igmp user add service-port 4 no-auth
multicast-vlan 92
  igmp version v2
  igmp multicast-vlan member service-port-list 4
  igmp mode proxy
  igmp program add batch start-index 0 ip 239.0.4.2 to-ip 239.0.4.145 hostip  10.146.34.233

  igmp program add batch start-index 144 ip 239.0.40.185 to-ip 239.0.40.224 hostip 10.146.34.233

  igmp uplink-port 0/6/0

multicast-vlan 80

  igmp version v2

  igmp mode proxy

  igmp program add batch start-index 285 ip 239.0.40.225 to-ip 239.0.40.231 hostip 10.146.34.233

  igmp program add batch start-index 292 ip 239.0.4.219 to-ip 239.0.4.248 hostip 10.146.34.233

  igmp program add batch start-index 322 ip 239.0.4.203 to-ip 239.0.4.217 hostip 10.146.34.233

  igmp uplink-port 0/6/0

Now, in order to watch SD channels we must configure the service-port :

service-port 4 vlan 92 vdsl mode ptm 0/0/0 multi-service user-vlan 20 tag-transform translate inbound traffic-table index 7 outbound traffic-table index 7

Then we cannot watch HD channels configured in Multicast VLAN 80.

When we are configuring IPTV service we must take in account the following steps:


1. Create Multicast VLAN

2. Configure uplink-port

3. Configure Igmp Programs

4. Create Igmp User associated to service-port

5. Associate Igmp Membership to service-port



If we compare configuration between SD Multicast VLAN and HD Multicast VLAN, we found that the only one difference is in igmp membership. 


We cannot watch channels for both Multicast-VLAN because of we must associate igmp membership to two Vlans. In the first configuration we have this association only for one VLAN.

In order to associate igmp membership to two VLANs, we must configure the following:

multicast-vlan 80

 igmp multicast-vlan member service-port-list 4

After of this configuration we have only one service-port associated to only one vlan but we can watch channels for two vlans.

Remember that If we do not know ID of service-port we can use the following command :

 (config-mvlan80)#igmp multicast-vlan member smart-vlan 92   ; It's 92 because of VLAN of service-port is 92

service-port 8 vlan 92 vdsl mode ptm 0/0/0 multi-service user-vlan 20 tag-transform translate inbound traffic-table index 7 outbound traffic-table index 7

Conclusion:

1. We must configure two multicast vlan and we must associate igmp membership to two vlans

2. We must create service-port for only one VLAN

3. We must create igmp user for this service-port
