You deploy a template to the devices to update the configuration
on the devices. Before deploying a template to a device, ensure that
you have not already assigned the template to the same device. If
you assign a template to a device and use the Deploy workflow to deploy
that template on the same device, even if the template is deployed
to the device, Junos Space Network Management Platform does not reflect
this managed status. The managed status of the device is shown as
"Space Changed" on the Device Management page.
You can also use this workflow to assign and publish the template
to the devices. You assign and publish a template to the devices to
set up this template for deployment. When you assign and publish a
template to the devices, the template is placed in queue. You can
review the accumulated configuration changes that will be deployed
to the devices.
To deploy or assign a template to the devices:
- On the Junos Space Network Management Platform user interface,
select Device Templates > Templates.
The Templates page is displayed.
- Select the device template that you want to deploy and
select Assign/Deploy Template from the Actions menu.
The Assign/Deploy Template page is displayed. This page displays
the devices on which the template can be deployed.
- From the Selected Template Version drop-down
list, select the version of the device template that you want to deploy
or assign to the devices.
- You can deploy the device template by selecting the devices
manually, filtering by device properties, using tags, or providing
a CSV file with filter criteria:
To select the devices manually, enter the search criteria
in the Search field and click the Search icon.
The list of devices are filtered by the search criteria.
To filter devices by device properties, select the check
box next to the appropriate device column on the Column Filter drop-down list.
To select a device by using tags, select an appropriate
tag from the Tag Filter drop-down list.
From Junos Space
Platform Release 17.2R1 onward, when you select devices by CSV, you
can choose to select all managed devices. Select the Include
All Managed Devices check box to list all managed devices for
selection.
To provide filter criteria using a CSV file, click the CSV Filter
icon and upload the CSV file with the filter criteria through the
Upload a CSV pop-up window.
- Select the devices on which you want to deploy the template
and click Next.
This page displays the devices you chose on the left and the
configuration to be deployed on the device on the right. You can also
view details such as device name, managed status, validation status.
If you specified device-specific values when creating the template
definition, the Variable column is displayed. This column displays
the validity of the value of the device-specific variable: PASS or
FAIL.
- (Optional) To validate the configuration on the device
before deploying, select the device and click the Validate on
Device link.
By validating the configuration, you ensure that the device
template is semantically correct. If the validation fails, change
the template parameters appropriately.
Note: If you select modeled devices that are in the Modeled
state, the Validate on Device link is disabled.
A job is triggered. You can view the details of the job from
the Job Management page. When the job is completed, the job ID is
displayed next to the Validate on Device link.
Note: If validation fails on all devices you selected, you cannot
deploy the template on devices. If validation fails on some devices
you selected, you can deploy the template to only those devices that
succeeded the validation.
- (Optional) To view the XML format of the configuration,
select the device and click the XML tab.
- (Optional) To view the CLI format of the configuration,
select the device and click the CLI tab.
- Click Next.
- Select whether to deploy the device template now or later
or whether to only assign and publish it.
To assign and publish the device template, select the Assign and Publish to pending configuration changes option
button.
To deploy the device template now, select the Deploy
Now option button.
To deploy the device template later:
Select the Deploy Later option button.
Enter the date in the Date field in the DD/MM/YYYY
format.
Enter the time in the Time field in the hh:mm
format.
Note: If you select modeled devices that are in the Modeled
state, the Deploy Now and Deploy Later buttons are disabled.
Note: If you publish the template, the configuration in the
template is deployed to the device along with the candidate configuration
for the device, with the Junos OS confirmed-commit functionality.
- Click Finish.
The Deploy Template Job Information page is displayed. You are
redirected to the Templates page.
Click OK to close the page.
The device template is deployed to the devices.
Note: You can check whether a template is deployed on all devices
from the Job Management page. Double-click the row corresponding to
the ID of the device template deployment job on the Job Management
page. The Job Details page is displayed. The Description column on
this page specifies whether the template is deployed on all devices.
If the device template is not deployed on all devices, this column
lists the reason why the template was not deployed. If there is an
error, the View Job Details page displays an error message. For more
information about the error messages, see Common Error Messages in Device-Related Operations.
Note: If you deploy the template when in SSOR mode, Junos Space
Network Management Platform automatically assigns the template to
the device. To subsequently modify the template, use one of the following
workflows:
Unassign the template from the device, modify the template,
and deploy the template by using the Deploy workflow.
Modify, approve, and deploy the template on the device
by using the Review/Deploy Configuration workflow in the Devices workspace.
