Hello,

I have actually 2 remote plant interconnected by 3750 layer 3 switch.
On the LAN, I have 2950 and 2960 layer 2 switch.

I have punctually many congestion problem. That's the reason why I plug Wireshark on a 2950 switch on the LAN and I see many many UDP packet with multicast destination address. I found that the source address is a video-camera. Punctually, the multicast flow are distributed on all switch port.

Then I have multicast flow which congest my network.
How can I manage these multicast flow on my cisco devices in order the flow just take the good way to the receiver (a video recorder) ?
Could you explain me how it works ?


Thanks in advance for your help.
