The Zero Touch Provisioning (ZTP) process on a Nokia SR Linux node is a device-centric mechanism initiated at boot time. It fundamentally relies on DHCP to acquire network connectivity and the location of a provisioning script. The device then downloads this script, along with any necessary software packages (RPMs) or images, from a web or FTP server and executes it to complete its configuration.

Nokia’s Fabric Services System (FSS) is a higher-level orchestration and automation platform for data center fabrics. While FSS utilizes ZTP to onboard new switches into the fabric, the ZTP process itself is independent of FSS. The deployment of a digital sandbox is a function managed by FSS, not a direct action performed by the device's native ZTP autoboot process.

A. DHCP is the primary mechanism used during ZTP to provide the device with its initial IP address, default gateway, and the location of the provisioning server via DHCP options.

B. A web (HTTP/HTTPS) or FTP server is the standard repository from which the device downloads its provisioning script, configuration files, and any required software packages or images.

C. The core of ZTP's automation is the downloading and execution of a provisioning script (e.g., a Python script), which performs the device's specific configuration tasks.

1. Nokia SR Linux R23.10.R1 System Management Guide, Section: "Zero touch provisioning". This section details the ZTP workflow: "When ZTP is enabled, the SR Linux device sends a DHCP discovery message on its management interface... The DHCP server responds with an offer that includes an IP address for the management interface and the location of a provisioning script... The SR Linux device downloads the script and executes it." This confirms that A, B, and C are integral parts of the process.

2. Nokia Data Center Fabric Solution Guide, Chapter 3: "Nokia Fabric Services System". This guide describes FSS as a platform for "fabric lifecycle automation," which includes "Day 0" operations like device onboarding via ZTP. It positions FSS as the orchestrator that leverages ZTP, confirming that FSS functions (like deploying a digital sandbox) are distinct from the ZTP process running on the switch itself.
