Troubleshooting Tip: Configuring Data Plan on FortiGate

[isaac_ra]

Description	This article describes the steps to configure a data plan on FortiGate for LTE. It explains how to enable data usage tracking and configure a data plan to control mobile data usage.
Scope	FortiGate.
Solution	To configure a data plan on FortiGate, follow these steps: Enable data-usage-tracking first, otherwise "config data-plan" will not be available: config system lte-modem     set data-usage-tracking enable Once data-usage-tracking is enabled, the sub-configuration data-plan will appear: config system lte-modem     set data-usage-tracking enable         config data-plan Set the billing-period to either daily, monthly, or weekly. If the billing period is set to monthly, the billing hour parameter is not available. Example configuration from the CLI: config system lte-modem     set data-usage-tracking enable         config data-plan             edit TEST1                 set target-sim-slot SIM-slot-2                 set data-limit 1000                 set data-limit-alert 83                 set billing-period daily                 set billing-hour 21             next             edit TEST2                 set target-sim-slot SIM-slot-2                 set data-limit 10000                 set billing-period monthly                 set billing-date 1 Important to note that when deploying the changes from FortiManager, the default values should not be altered and set to 0. For instance, a default value of 4294967295 for billing-hour means that this option is deactivated; if set to 0 and billing-period monthly is chosen, the configuration install will throw an error: See this document: config system lte-modem for more information.
