In a hotel IPTV environment we have video servers and setop boxes as streaming clients. The network is build with catalyst 4506 (central switch) and catalyst 3560 (edge switches). All components are igmpv2 speaker, on the switches is igmp snooping enabled. Between the setop-boxes and the switches are broadband cablemodems connected. Up to 5 setop boxes share a switchport. Some times, setop boxes becomes disconnected from network and can?t send a leave for the actual stream. This streams stay for long time and consumes bandwith. Video servers send periodic igmp general queries and setop boxes answers with membership reports.
Is there a change to get the edge switches listen to general queries and memebership reports to find those "ghost streams" and clear them after the maximum response timeout?
