Hello. I have IPTV network with IPTV multicast server, Catalyst 3750G Enhanced Image with IGMP snooping and queirer enabled, and SRW248G4 switches to connect clients. Clients are succesfully connecting to snooping groups (accordong to "show ip igmp snooping groups"), and also video is shown by client devices.
But following issue is observed: when client device is connected/disconnected from the SRW248g4 port or Catalyst 3750G port, video stream freezes on all devices over network. what can be the reason of this issue?
