Problem analysis:
Possible causes:
1. The OLT multicast configuration is incorrect.
2. The ONT multicast configuration is incorrect.
3. The STB is abnormal.
Handling process:
1. Check whether the OLT configuration is normal.
[btv-config]
<btv-config>
monitor uplink-port igmp port 0/8/0
monitor multicast traffic vlan 111 enable
btv
igmp user add 0 service-port 2 no-auth igmp-version v2
multicast-vlan 111
igmp version v2
igmp mode proxy
igmp program add batch start-index 0 ip 232.1.x.x to-ip 232.1.x.x
igmp uplink-port 0/8/0
#
2. The debugging switch shows that the ONT does not send the packet to the OLT.

3. According to the multicast packet statistics, the OLT does not receive multicast packets from the user side either.
(config)#display igmp statistic service-port 2
{ <cr>||<K> }:
Command:
display igmp statistic service-port 2

4. Check the port connected to the STB and it is found which is up, and multicast packets are sent to the ONT. Therefore, it is suspected that the ONT does not forward packets to the OLT.

5. Check the ONT configuration. It is found that the ONT is not enabled with multicast.
Root cause:
If the ONT works in Layer 3 multicast mode, the multicast function must be enabled.
Solution:
After the IGMP function of the ONT is enabled, services are normal.
