Thanks. After i enable ip igmp IPTV works fine.
Now i have another problem. In the data center HP 2620 switch, i have Avaya Server,IPTV Server, Internet Modem connected.
In HP 2620, i have created two VLAN- default for voice and internet and vlan 2 for IPTV.
IPTV is working only when STB is connected directly. But i have another switch connected through fiber link and connected to another hp 2620 48 port switch where IPTV not working.
WHen i tried to change port 52 to trunk, IPTV started working but Internet and phone stopped
