Device Template Operations on Threat Defense High Availability Devices
You can apply device templates on threat defense High Availability (HA) devices after device registration. Failover configurations are not supported in device templates. Any failover configurations and monitored interfaces that are already part of the target HA device pair configurations are not modified. You cannot map any template interfaces to failover interfaces.
You can generate a device template from an HA device pair. Template operations such as application of template on device, template generation, import, and export of template, can be performed only on primary or active HA devices. You cannot perform these operations on secondary or standby devices.
