Peering Templates


Peering Templates allow users to create their own reusable session configuration files. When the default ProVision session configuration template doesn't do everything required for your specific use case, you can create your own template that does. Revisions to Peering Templates are tracked, and a template may be reverted to a previous version at any time. 


Peering Templates are accessible to Admin users from the Admin Preferences → Peering page, under Peering Settings. 


Viewing Templates

View the Template List by navigating to the Admin Preferences page, in the Admin area of ProVision. From there, click the "Peering" sub-tab button top view Peering Settings.

Next to "Templates", click "Manage Custom Templates". 

The Template List will open, displaying all existing Peering Templates. 

Click on any template to open Template Details, where you can edit, delete, or preview the template.

To return to the Template List, click the "Template List" button at the top right of the page. 

Add a Template

From any page in the Peering Templates area, click the "Add Template" button on the right side of the page header to start a new template.

In the Add Template form, enter a name for the template and the template body. When complete, click "Add". 

The "Template Details" view displays for the newly created template, here you can update, preview, or delete the template. 

The "Revision History" section is available at the bottom of the page in this view, but will only display data if previous updates have been made to the template. 


Delete a Template

From the Template Details view for the desired template, click the "Delete Button".  Note: The deletion is immediate and permanent - use with care!

From the Template Details view, edit the template by clicking inside the template body and typing the desired changes - if you need a reminder as to syntax or variables, click the help icon (Question Mark button) at top right to open the template editing guide.
