Abstract
A method for identifying an error condition due to a faulty cable connection in a network comprising a plurality of computer systems, at least one of the computer systems including a network adapter with the network adapter including a media access control (MAC) unit, includes initializing a plurality of mechanisms for tracking a plurality of conditions in the MAC of the network adapter. The method further includes receiving a transmit demand request in the network adapter and updating the plurality of mechanisms according to a current status of each of the plurality of conditions. In addition, the method includes determining whether a predetermined threshold has been reached in one or more of the plurality of mechanisms, wherein when one or more of the plurality of mechanisms has reached the predetermined threshold, a faulty cable connection is identified. In a system aspect, the system includes a plurality of counting mechanism for tracking each of a plurality of error conditions. The system further includes a media access control (MAC) unit for differentiating each of the plurality of error conditions. In addition, the system includes an error identification mechanism for determ…
