This is because the Cisco DNA Center Template Editor feature is a tool that allows the network administrator to create and deploy configuration templates to multiple network devices. The configuration templates use parameterized elements or variables, which are placeholders for values that can be customized for each device. For example, a variable can represent the hostname, IP address, or interface number of a device. The parameterized elements or variables can be defined manually or automatically using the Cisco DNA Center inventory.
