diagDisablePost
Figure 4-14 shows the
diagDisablePost
command, which disables POST
processing. The boot time without POST processing is approximately
50 to 55 seconds. A switch rebooted without POST generates the
DIAG-POST_SKIPPED error.
NOTE:
Always execute POST processing to ensure the operational status of the switch
during the power up stage.
switch:admin> diagDisablePost
Committing configuration...done.
On next reboot, POST will be skipped.

diagEnablePost
Figure 4-15 shows the
diagEnablePost
command, which enables POST
processing. The boot time with POST processing is approximately
110 to 120 seconds for warm POST, and 165 to 175 seconds for cold POST.
POST processing is enabled by default.
switch:admin> diagEnablePost
Committing configuration...done.
On next reboot, POST will be executed.

diagShow
Figure 4-16 shows the
diagShow
command, which summarizes the diagnostics
results, including POST results, since the switch was last booted. The
following table describes the fields.
The
diagShow
command can be looped. For example,
diagShow 4
executes
diagShow
every four seconds until you stop it by pressing Enter. This command
can be used to isolate a bad GBIC module. A port with a changing LLI_errs
value is prefixed by
**
in the display.
