Templates and high availability
You can apply device templates on Firewall Threat Defense high availability devices after device registration. High availability-specific configurations are not supported in device templates. Any high availability configurations and monitored interfaces that are already part of the target high availability device pair configurations are not modified. You cannot map any template interfaces to failover interfaces.
You can generate a device template from a high-availability device pair. Template operations such as application of the template on a device, template generation, importing, and exporting of a template, can be performed only on the active unit. You cannot perform these operations on the standby unit.
