ALR0646W The Discarded Class 3 Frame Rate of port port name in switch switch name was measured to be measured value cnt/s, which violated the defined warning-idle boundary value of boundary value cnt/s.

Explanation

The Discarded Class 3 Frame Rate measures the rate at which the port Discarded Class 3 Frames for any reason. Frames can be discarded due to many reasons, for example invalid addressing or header contents, or due to timeout caused by lack of buffer credits. Other error metrics may help in narrowing down the reason for the discards. A threshold was defined on this metric, which causes the measured value to be compared to the defined boundaries for each set of performance statistics collected from the switch.

This message indicates that a threshold boundary violation occurred. In this case, the specified port in the switch has a Discarded Class 3 Frame Rate 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.
