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.
To enable you to more easily reuse templates or template stacks, you can use template and template stack variables to replace IP addresses, Group IDs, and interfaces in your configurations. Template variables are defined at either the template or template stack level and you can use variables to replace IP addresses, IP ranges, FQDN, interfaces in IKE, VPN and HA configurations, and group IDs. If a variable for an object is defined in both the template and template stack, then the variable defined in the template overrides the variable defined in the template stack because template configurations have higher priority than template stack configurations. Additionally, you may override a template variable at the template stack level if needed.
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:
- SelectandPanoramaTemplatesManage(Variables column) the template or template stack for which you want to create a variable.
- Addthe new variable.A variable name must start with the dollar ( $ ) symbol.
Variables can also be created inline where variables are supported.
- Name the new variable. In this example, the variables are named$DNS-primaryand$DNS-secondary.
- Select the variableTypeand enter the corresponding value for the selected variable type.For this example, selectIP Netmask.
- (Optional) Enter a description for the variable.
- From theTemplatedrop-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.
- Selectand edit Services.DeviceSetupServices
- Type$DNS-primaryor select it from the drop-down forPrimary DNS Server.
- Type$DNS-secondaryor select it from the drop-down forSecondary DNS Server.
- ClickCommitandCommit and Pushyour changes to managed firewalls.When you push a device group configuration with references to template or template stack variables, you mustEdit SelectionsandInclude Device and Network Templates.
- Verify that the values for all variables were pushed to the managed devices.
- From theContextdrop-down, select a firewall that belongs to the template stack for which the variable was created.
- 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.
