38 bytes (not 48) including the SOF and EOF. The too_short error statstics counter is incremented whenever a frame, bounded by an SOF and EOF, is received and the number of words between the SOF and EOF is less than 7 words (6 words header plus 1 word CRC), i.e. If an eof is corrupted or data generation is incorrect a too_long error is reported. Frames that were longer than the FC maximum (SOF+header+2112bytes+CRC+EOF). Suggested actions would be to replace the cable or SFP, move cable to another port, or run porttest.įC frames are 2148 bytes maximum.
crc_err and enc_out errors together imply GBIC/SFP problem. The receiving port uses the same formula to check and compare. A mathematical formula generates counters at the sending port. Enc_out errors and crc_err together imply GBIC/SFP problem Reinitialisation / reboots of the associated Nx-port can also cause these errors.Įnc_out errors on their own imply a cable/connector problem. Note: Minimum compliance with the link bit error rate specification on a link continuously receiving frames would cause approximately one error every 20 minutes. Suggested actions would be to replace the cable or SFP, move cable to another port, or run porttest. Words in/outside of frames are encoded, if this encoding is corrupted or an error is detected enc in/out is generated.
8bit/10bit encoding errors occurred in words (ordered sets) in/outside the Fibre Channel frame. If this counter is increasing, SFP/cable needs to be checked/replaced. Words inside of frames are encoded, if this encoding is corrupted or an error is detected enc_in is generated. This would be a place to gauge the traffic.Įnc_in - 8bit/10bit encoding errors inside frame. – Counters representing the number of frames transmitted.
