Graphing switch port data 49Field DescriptionFCSErrors A count of frames received on a particularinterface that are an integral number of octetsin length but do not pass the FCS check. Thecount represented by an instance of this object isincremented when the frameCheckError status isreturned by the MAC service to the LLC (or otherMAC user). Received frames for which multipleerror conditions occur are, according to theconventions of IEEE 802.3 Layer Management,counted exclusively according to the error statuspresented to the LLC.InternalMacTransmitErrorsA count of frames for which transmission on aparticular interface fails due to an internal MACsublayer transmit error. A frame is only counted byan instance of this object if it is not counted by thecorresponding instance of either the LateCollisionsobject, the ExcessiveCollisions object, or theCarrierSenseErrors object.InternalMacReceiveErrorsA count of frames for which reception on aparticular interface fails due to an internal MACsublayer receive error. A frame is only countedby an instance of this object if it is not countedby the corresponding instance of either theFrameTooLongs object, the AlignmentErrorsobject, or the FCSErrors object.The precise meaning of the count representedby an instance of this object is implementationspecific. In particular, an instance of this objectmay represent a count of receive errors on aparticular interface that are not otherwise counted.CarrierSenseErrors The number of times that the carrier sensecondition was lost or never asserted whenattempting to transmit a frame on a particularinterface. The count represented by an instanceof this object is incremented at most once pertransmission attempt, even if the carrier sensecondition fluctuates during a transmission attempt.Nortel Ethernet Routing Switch 5500 SeriesConfiguration - System MonitoringNN47200-505 03.01 Standard5.1 27 August 2007Copyright © 2005 - 2007, Nortel Networks.
