A packet switch includes an error management module in addition to various components that facilitate routing of data packets through the packet switch. The components generate error codes indicating errors occurring in the packet switch and provide the error codes to the error management module. The error management module select error codes generated by the components and generates an error log based on the selected error codes. Each component is inhibited from providing the same error code to the error management module more than once until the component receives an acknowledgement for that error code from the error management module. A user can access the error log during operation of the packet switch to monitor performance of the packet switch.
