What are zero-touch provisioning use cases? See how the basic zero-touch provisioning process works. ZTP can use a user-provided script to connect to a configuration management platform, such as Puppet, CFEngine, Chef or a custom tool. ZTP carries out the basic configuration, after which the switch can be deployed in an environment where custom configuration changes are made. The protocol used - DHCP, for example - provides the gateway address, the domain name and the server location. The port configuration and IP address are automatically provisioned based on the location requirements. Then a network switch sends out a request through DHCP or TFTP to get the location of its centrally stored image and configuration, which it downloads and runs. When a ZTP-enabled device is powered on, it runs a boot file that sets up the device's configuration parameters.
