Greetings friends,

Does anyone have some basic troubleshooting skills for troubleshooting a video stream from one switch to another.  I have about 100 access switches, with 3 distribution and 2 core format.  Some people are testing streaming between the switches and some of the streams work and some only transmit the audio.  Does anyone know commands I can type in to check the stream, or to see if anything is getting blocked at all between or get any sort of information at all?

All the settings on their devices are the same and sometimes the video gets through but with bad quality.

The stream can get up too 200mbps. 

All the switches in use are cat4510 and 3850s.  All 1gig ports.  

Thanks in advance
