where:
none does not change the active segments. The default is none.
Also, when the reboot is completed, the access point
resets this value to none.
boot changes the inactive boot segment to the active boot
segment.
data changes the inactive data segment to the active data
segment.
both changes both the boot and data inactive segments to the
active segments.
Example
To change the inactive boot and data segments to active at the next
reboot, enter:
sdvars set setactivepointers both
sdvars set
nextpoweruptime
Purpose
Sets the nextpoweruptime command to set the internal variable
nextpoweruptime to a countdown time so that when 0 is reached, the
access point will reboot. When the nextpoweruptime counter reaches 0,
the access point checks the value of the setactivepointers variable, takes
the appropriate action, and then reboots.
Syntax
sdvars set nextpoweruptime dd:hh:mm:ss
where dd:hh:mm:ss is how far in the future the reboot is to begin.
Example
To reboot the access point 2 hours from now, enter:
sdvars set nextpoweruptime 00:02:00:00
Note
If you need to terminate the reboot, you can do so by setting
nextpoweruptime to 0 if it has not already been reached by the
countdown. By resetting nextpoweruptime to 0, the timer is
stopped so the unit does not reboot.
