Example: Consider the following script file commands:

sdvars set starttime (continued)
where dd:hh:mm:ss is how far in the future the reboot is to begin and
dd is days.
hh is hours.
mm is minutes.
ss is seconds.
sdvars set starttime 00:00:05:00
Note: If you need to stop the download, you can do so by setting starttime
to 0 if it has not already been reached by the countdown. Resetting
starttime to 0 stops the timer and the download process.
sdvars set checkpoint
checkpoint variable is useful for monitoring the progress of a script file as
it is executed. You can set the checkpoint variable to a different value after
each script command, and then query the checkpoint value using SNMP
to determine the progress of the download.
sdvars set checkpoint value
where value is a whole number.
sdvars set checkpoint 1
fe ab
sdvars set checkpoint 2
TFTP get * uap.prg ab
sdvars set checkpoint 3
reboot
When the software download is started, you can use SNMP to query its
progress by reading the checkpoint variable. If the variable has a value of 2,
you know that the access point is trying to execute the TFTP get
statement. If the value is 3, you know the script has completed and the
reboot was executed. The value of the checkpoint variable may also be
helpful in determining where an error occurred if the script fails.
