I have a customer with a switch stack comprised of 7 3750E-24-PD running c3750e-universal-mz.122-46.SE. The switches are running in StackWise Plus mode. This stack is providing the backbone of an elborate HD audio video system using Netstreams encoders and decoders. The customer has recently reported that he is losing video on some TVs. The encoder/decoder pairs use multicast groups to establish zones.
The vendor, Netstreams has asked what the throughput on the backplane of this stack is, as he believes it to be a backplane issue. I found that 'show controllers utilization' show percentage bandwidth figures. Are there any other commands that are useful in diagnosing backplane/switch throughput?
