diagEnablePost
Figure 53 shows the diagEnablePost command, which enables POST processing.
The choice remains in effect across power-on and power-off cycles until toggled by
the user. The startup time with POST processing is approximately 110 - 120
seconds for a warm POST and 165 - 175 seconds (based on a 2109 Model S16)
for a cold POST. The factory default enables POST processing.
diagShow
Figure 54 on page 108 shows the diagShow command, which summarizes the
diagnostic results since the switch last turned on, including POST results. The fields
are described in Table 34 on page 108.
The command also allows you to loop on the command. For example, if you enter
diagShow 4
, the diagShow command is executed every 4 seconds continuously
unless stopped by pressing Enter. This is used to isolate a bad GBIC. A port with a
changing value in the low-level interface count field (LLI_errs) is prefixed by two
asterisks (**) in the display.
