> # Interface Port Monitoring FrameErrors (9020)

> Field | Description
> --- | ---
> Invalid CRCs | Count of frames received with invalid CRC. This count is part of the Link Error Status Block (LESB). (FC-PH 29.8). Loop ports should not count CRC errors passing through when monitoring. Note, this is a Fibre Channel only statistic.
> ELPFailures | The number of Exchange Link Parameters Switch Fabric Internal Link service request failures detected by the FC-Port.
> Frags | The number of fragmented frames received by the FC-port.
> Runts | The number of frames received by the FC-port that are shorter than the minimum allowable frame length .
> Jabbers | The number of frames received by the FC-port that are longer than a maximum frame length .
> TooLongs | The number of frames received by the FC-port where the frame length was greater than what was agreed to in FLOGI/PLOGI.
> TooShorts | The number of frames received by the FC-port where the frame length was lesser than what was agreed to in FLOGI/PLOGI.
> Unknowns | The number of unknown class frames received by FC Port.
> EOFa | The number of frames received by FC-port with EOF aborts.
> Framing | The number of framing errors.
