Question:
Why The IPTV faults include the image interruption and slow channel
switching frequently?
Reason:
The fault may be caused by the following:
The data configuration is incorrect and the network is faulty.
Solution:
Check whether the multicast configuration is correct.
2. Query the multicast group MAC address of the adding packet
received by the main control card, the added multicast group
port, and the multicast VLAN. Check whether the MAC address
corresponds to the configured multicast IP address.
3. Display the ONU added to the multicast group and the ONU
port number. If the multicast group is configured successfully,
it can be queried. If the ONU sends the adding packet, the
ONU added to the multicast group and the ONU port number
can be queried.

Clearly document

it is useful, but how can we to whether the network is fault and whic part is fault?

Thanks for sharing .....It's useful
