Usage
Information
Before you use this command to run diagnostic test, make sure the switch is offline
(
offline system
command).
You are prompted to reboot when the off-line diagnostics complete.
Use the
show diag
command to view a summary of diagnostic information
presented for each Z9500 CPU.
At the end of offline diagnostic tests, a test report is generated. The filename of the
report is TestReport-{CP/LP/RP}-
N
.txt, where {CP/LP/RP}-
N
identifies the CPU and
CPU ID on which the diagnostics were run: Route Processor 0, Control Processor
0 or a line-card CPU {0–2}. The report is stored at flash:// and ramdisk:/diagnostic.
To view the test report, use the
show file flash://
filename
command. A
sample
filename
is TestReport-LP-2.
