diagShow
Print diagnostic results since the last boot.
Synopsis
diagShow [nSeconds]
Availability All users
Description Use this command to print the following information generated since the
last switch reboot:
• State of all ports in the switch resulting from diagnostics run since the
last reboot. Ports that passed diagnostic testing are marked OK. Ports
that failed one or more diagnostic tests are marked BAD.
• Current state of ports. Active ports are UP and inactive ports are DN.
• Frame counts for active ports – the number of frames transmitted is
frTx
and the number of frames received is
frRx
.
The “
LLI_errs
” is the total of the port’s eight statistic error counters:
ENC_in, CRC_err, TruncFrm, FrmTooLong, BadEOF,
Enc_out, BadOrdSet, DiscC3.
• State of central memory based on the results of diagnostics run since the
last reboot. OK if previous centralMemoryTest executions passed;
FAULTY if the switch failed
centralMemoryTest
.
• Total diagnostic frames transmitted and received since last reboot.
The totals represent the cumulative number of frames transmitted and
received by the diagnostic functional tests (
portLoopbackTest
,
crossPortTest,
or
spinSilk
for the transmitted count only) for all
ports since the last reboot. (If the switch is rebooted with POST
disabled,
diagShow
indicates the total as
0
.)
The transmitted and received values may not always be the same; for
example, they may not be the same if an error occurred in one of the
ports during one of the tests above.
This command can also be executed by using the
s
(Stats) option of the
QCSL diag prompt, which is generated when a diagnostic test is keyboard
interrupted.
