diagShow [nSeconds]

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.
•
Current speed configuration for all ports:
•
Frame counts for active ports. The number of frames transmitted is listed as frTx and the
number of frames received is listed as 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 should be the same. If they are not the same it may
indicate an error has occurred in one of the ports during one of the tests above.
This command may also be executed by using the s (Stats) option of the QCSL diag prompt which
is generated when a diagnostic test is keyboard interrupted.
It can also be looped by specifying the nseconds operand. This operand enables you to specify a
repeat interval for this command. If a repeat interval is specified the command continues to execute
until interrupted. For example diagShow 4 executes the diagShow command every four seconds
unless stopped by a keyboard interrupt.
Also use this command to isolate a bad GBIC. A changing "LLI_errs" value prefixed by "**"
indicates a port is continuing to detect errors.
Operands This command has the following operand:
nSeconds
1-56
Specify the repeat interval (in seconds) between executions of the diagShow
command. If a repeat interval is specified the command continues to execute
until interrupted. If this operand is not used, the default behavior is to display the
information once. Valid values are from 1 to 2**32. This operand is optional.
