ALR0686W The Port Congestion Index of port port_name in device device_name was found to be measured_value Counts, which violated the defined warning-idle boundary value of boundary_value Counts.

Explanation

Port Congestion Index estimates the degree to which frame transmission was delayed due to a lack of buffer credits. This value is generally between 0 (no congestion) to 100, but can exceed 100 if buffer credit exhaustion persisted for an extended amount of time. A threshold is defined on this metric, which can be used to compare the value of Port Congestion Index with the defined boundaries for each set of performance statistics collected from the storage system or switch.

A threshold boundary violation occurred. The specified port in the storage system or switch has a Port Congestion Index value that is less than or equal to the warning-idle boundary, but greater than the critical-idle boundary that was defined for the related threshold.
