FCS Errors: The total number of packets received by the port that had a bad Frame Check Sequence.
Alignment Errors: Total Alignment Errors frames within the proper size (64 to 1518 octets) received by the port.
Frame T oo Long: Total frames received by the port that were longer than 1518 octets (excluding framing bits, but including FCS octets).
Short Events: Total frames received by the port that were shorter than 64 octets or activity duration was shorter than the event, ShortEventMaxTime. (74 to 82 bit times)
Runts: The total number of packets received that were less than 64 octets due to collisions or activity duration that was greater than the ShortEventMaxTime event and less than the ValidPacketMinTime event.
Collisions: Total collisions.
Late Events: Total events received by the port where the activity duration is greater than the LateEventThreshold.
Very Long Events: Total events received by the port where the activity duration is greater than the MAU Jabber Lockup Protection timer TW3.
Data Rate Mismatches: Total frames received by the port with no collisions and with an activity duration that was greater than the ValidPacketMinTime event. Also frequency (data rate) is detectably mismatched from the local frames mismatch frequency.
Auto Partitions: Total number of times the port was
Isolates (100Mbps only): Total isolates for 100Mbps
