Abstract
Methods and arrangements to monitor communication components such as a network adapters for activity, and identify components that have lower than normal levels of activity are provided. An identified communication component can become suspect component and a candidate for further testing, including different forms of interrogation. Process for interrogating candidates can include generating and sending test packets having the media access control (MAC) address of the candidate to the candidate and if activity is not detected subsequent to the interrogation, the candidate can be flagged as a failed component. Correspondingly, the component can be deactivated and removed from service. In a further embodiment, a backup component can be activated and assume the role previously held by the failed component.
