> # FC Interface Monitor Frame Errors

> The Monitor dialog boxes have special Monitor Dialog Controls.

> Field | Description
> --- | ---
> InvalidCrcs | The number of invalid CRCs detected by the FC-Port. Loop ports should not count CRC errors passing through when monitoring.
> ELPFailures | The number of Exchange Link Parameters Switch Fabric Internal Link service request failures detected by the FC-Port. This is applicable to only Interconnect_Port, which are E_Port or B_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 regardless if the CRC is good or not.
> Jabbers | The number of frames received by the FC-port that are longer than a maximum frame length and also have a CRC error.
> TooLongs | The number of frames received by the FC-port where the frame length was greater than what was agreed to in FLOGI/PLOGI. This could be caused by losing the end of frame delimiter.
> TooShorts | The number of frames received by the FC-port where the frame length was less than the minimum indicated by the frame header (normally 24 bytes), but it could be more if the DFCTL field indicates an optional header should be present.
> 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. This denotes that the FC-port detected an inconsistency of frame structure.
