We are having issues with our Equalogic SAN reporting Disk Latency Issues. Equalogic points to the switches which show no signs so far of any latency issue or drops. These are 3750E series switches with no routing, just switching and all data is going through one single switch so no transfers across a network.
Any ideas would be really appreciated.

Check your input/output interface buffers for drops and or overruns.

Frank,
I think I have but what is the best command to use to do that? I've done the show switch diag and the show tech
any better command?
