We are experiencing a lot of time spent with the buffer credits hitting 0. On average for of our ISL ports are hitting 0 between 30 and 50% of the time. The buffers are set to the default 16, would increasing the number of credits help our issue. I know there will be many questions on this thread back to me about the current setup and I will do my best to answer them. I am new to this environment so I will do my best.

portbuffershow will display allocated bb credits. There are a lot of reasons why credits will continually hit 0. This could range from long distance settings incorrect for actual distance, poor SAN design, non-recommended oversubscription of ISL's or high latency / slow drain devices in the network.
