In my IPTV infrastructure, I have configured several Alcatel switches to handle multicast traffic. The main switch is connected to an IPTV streamer, and the cascaded switches distribute the multicast streams to televisions. Here are the key points:
Current Configuration:
The switch with the streamer has multicast enabled and operates correctly. Features such as IGMP Snooping, Querier Forwarding, and Spoofing are configured.
The cascaded switches are also configured to handle multicast, with features like IGMP Snooping, Proxying, and Zapping enabled.
VLAN 12 is used for IPTV, and multicast routing appears to be properly set up.
Observed Issue:
When the TV is directly connected to the main switch with the streamer, IPTV streams work flawlessly.
However, when the TV is connected to a cascaded switch, the image frequently "freezes," leading to an unsatisfactory user experience.
