ABTS Rx The number of ABORT sequences received on the port. ABTSs are

responses to the error condition when a frame or sequence of frames are lost

or out of order.

Port Statistic Description

CRC Errors The number of Cyclic Redundancy Check (CRC) errors that are detected in

frames passing through the port since the last switch reset or since the

counters were cleared.

CRC errors can be caused by the following conditions:

• Connection problems with a remote device

• Link data corruption caused by a high number of Invalid TX words

• Bad cabling or other electromagnetic interference

• Partial SFP insertion

Short Frames The number of frames that are shorter than the minimum allowed frame size.

Long Frames The number of frames that have exceeded the maximum allowed frame size.

Invalid Words The number of invalid 10-bit words received on the port. This is typically

caused by a link corruption such as a code violation (10b/8b decoding),

framing error, or a disparity error.

Missing SOF/EOF The number of frames that are missing their Start-of-Frame (SOF) and/or

End-of-Frame (EOF) ordered sets.
