Command line
1. Log into the IX20 command line as a user with full Admin access rights.
Depending on your device configuration, you may be presented with an
Access selection
menu
. Type
admin
to access the Admin CLI.
2. At the command line, type
config
to enter configuration mode:
> config
(config)>
3. Schedule system maintenance:
a. Configure the time of day that the maintenance window should start, using the syntax
HH
:
MM
. If the start time is not set, maintenance tasks are not scheduled and will not be
run.
(config)> system schedule maintenance from
HH
:
MM
(config)>
The behavior of the start time varies depending on the setting of the duration length,
which is configured in the next step.
n
If the duration length is set to
0
, all scheduled tasks will begin at the exact time
specified in the start time.
n
If the duration length is set to
24 hours
, the start time is effectively obsolete and
the maintenance tasks will be scheduled to run at any time. Setting the duration
length to
24 hours
can potentially overstress the device and should be used with
caution.
n
If the duration length is set to any value other than to
0
or
24 hours
, the
maintenance tasks will run at a random time during the time allotted for the
duration window.
n
If the duration length is set to one or more hours, the minutes field in the start time
is ignored and the duration window will begin at the beginning of the specified hour.
b. Configure the duration length (the amount of time that the maintenance tasks will be run).
If
0
is used, all scheduled tasks will begin at the start time, defined in the previous step.
