Configure a Template or Template Stack Variable
How to create a variable in a template or template stack
and push it to firewalls and appliances.
You can use template and template stack variables to replace IP addresses, IP ranges, FQDN,
interfaces in IKE and VPN, and Group IDs in your configurations. If multiple
templates in the template stack use different variables for the same configuration
object, the variable value inherited by the template stack is based on the order of
inheritance described in Templates and
Template Stacks. Additionally, you can override a template value using a
template stack variable to manage a configuration object from the
template stack.
Variables allow you to reduce the
total number of templates and template stacks you need to manage,
while allowing you to keep any firewall- or appliance-specific values.
For example, if you have a template stack with a base configuration,
you can use variables to create values that do not apply to all
firewalls in the template or template stack. This allows you to
manage and push configurations from fewer templates and template
stacks while accounting for any firewall- or appliance specific
values that you would otherwise need before you can create a new
template or template stack.
To create a template or template
stack variable:
- Log in to the Panorama Web Interface.
- Create a template and template stack.
- Select and Manage (Variables column) the template or template stack for which you want to create a variable.
- Add the new variable.A variable name must start with the dollar ( $ ) symbol.
- Name the new variable. In this example, the variables are named $DNS-primary and $DNS-secondary.
- Select the variable Type and
enter the corresponding value for the selected variable type. For this example, select IP Netmask.
- Enter the corresponding value for Type.
- Click OK and Close
Variables can also be created inline where variables are supported.![]()
- From the Template drop-down, select the template or template stack to which the variable belongs.
- Enter the variable in the appropriate location.For this example, reference the previously defined DNS value.
- Select Device.
- From the Template drop-down, select the template or template stack to which the variable belongs.
- Select .
- Edit the Services.
- Type $DNS-primary or select it from the drop-down for Primary DNS Server.
- Type $DNS-secondary or select it from the drop-down for Secondary DNS Server.
- Click OK.
- Click Commit and Commit
and Push your changes to managed firewalls.When you push a device group configuration with references to template or template stack variables, you must Edit Selections and Include Device and Network Templates.
- Verify that the values for all variables were pushed
to the managed devices.
- From the Context drop-down, select a firewall that belongs to the template stack for which the variable was created.
- Select .
- Settings with values defined by a template or template
stack are indicated by a template symbol ( ). Hover over the indicator to view to which template or template stack the variable definition belongs. When viewing from the firewall context, the variables display as the IP address you configured for the variable.

- Troubleshoot Connectivity to Network Resources to verify your firewalls can access your network resources.
