Brocade 3800 portstatshow output

[Swee Lean Heng]

Hi,
can anyone let me know what do the statistics for 'er_enc_out', 'tim_rdy_pri' and 'tim_txcrd_z' really mean from portstatshow output?

[Iain F. Brown]

Help portstatsshow to get information.

tim_rdy_pri Time R_RDY high priority
tim_txcrd_z Time BB_credit zero
er_enc_out Encoding error outside of frames


Additional information.

er_enc_out: Receive link: the number of 8b/10b encoding errors recorded outside frame boundaries.
This number may become nonzero during link initialization but indicates a problem if it increments
faster than the allowed link-bit error rate (approximately once every 20 minutes).

tim_rdy_pri: The amount of time (measured in proprietary ticks) that R_RDY transmission has higher priority than
frame transmission.

tim_txcrd_z: Time that this port cannot transmit frames due to a transmit buffer-to-buffer credit of zero.

Hi,
normally what can be the likely causes if er_enc_out has values in the millions and keep increasing?

[Iain F. Brown]

If a high (several thousand) er_enc_out errors are experienced on a particular port, the indications are that the signal is marginal
between the connected device transmit port and the switch receive port.
The diagnosis: marginal GBIC or cable on the connected device. Fibre or SCSI patching have also been known to cause these errors. Link initialization increments these values also.
