Chapter 3 Configuring and graphing ports 91Reference for the BayStack 380-24F Gigabit Switch Management SoftwareFrameTooLongs A count of frames received on a particular interface thatexceed the maximum permitted frame size. The countrepresented by an instance of this object is incrementedwhen the frameTooLong status is returned by the MACservice to the LLC (or other MAC user). Received frames forwhich multiple error conditions occur are, according to theconventions of IEEE 802.3 Layer Management, countedexclusively according to the error status presented to theLLC.SQETestErrors A count of times that the SQE TEST ERROR message isgenerated by the PLS sublayer for a particular interface.The SQE TEST ERROR message is defined insection 7.2.2.2.4 of ANSI/IEEE 802.3-1985 and itsgeneration is described in section 7.2.4.6 of the samedocument.DeferredTransmissions A count of frames for which the first transmission attempt ona particular interface is delayed because the medium is busy.The count represented by an instance of this object does notinclude frames involved in collisions.SingleCollisionFrames A count of successfully transmitted frames on a particularinterface for which transmission is inhibited by exactly onecollision. A frame that is counted by an instance of this objectis also counted by the corresponding instance of either theifOutUcastPkts, ifOutMulticastPkts, or ifOutBroadcastPkts,and is not counted by the corresponding instance of theMultipleCollisionFrames object.MultipleCollisionFrames A count of successfully transmitted frames on a particularinterface for which transmission is inhibited by more than onecollision. A frame that is counted by an instance of this objectis also counted by the corresponding instance of either theifOutUcastPkts, ifOutMulticastPkts, or ifOutBroadcastPkts,and is not counted by the corresponding instance of theSingleCollisionFrames object.LateCollisions The number of times that a collision is detected on aparticular interface later than 512 bit-times into thetransmission of a packet. Five hundred and twelve bit-timescorresponds to 51.2 microseconds on a 10 Mb/s system.A (late) collision included in a count represented by aninstance of this object is also considered as a (generic)collision for purposes of other collision-related statistics.ExcessiveCollisions A count of frames for which transmission on a particularinterface fails due to excessive collisions.Table 34 Ethernet Errors tab fields (continued)Field Description
