  • Page 3: Restrictions For Autonomic Networking

    Restrictions for Autonomic Networking General Restrictions • Autonomic networking only supports unique device identifier (UDI)-based devices. • Autonomic networking and Zero Touch Provisioning (ZTP) are different zero touch solutions. It is recommended that you do not test or use autonomic networking and ZTP at the same time. Information About Autonomic Networking Overview of Autonomic Networking The aim of autonomic networking is to create self-managing networks to overcome the rapidly growing complexity of the Internet...
  • Page 4 Autonomic Networking Infrastructure The Autonomic Networking Infrastructure (ANI) feature simplifies the network bootstrap functionality by removing the need for any kind of prestaging, thereby allowing devices to join a domain securely, after which devices can be configured. The goal of the Autonomic Networking Infrastructure feature is to make new and unconfigured devices securely reachable by an operator or network management system.
  • Page 5 New Device Joining the Autonomic Network The figure below illustrates how a new device joins an autonomic network. Figure 2: New Device Joining the Autonomic Network 1 The new device sends out a hello message to the neighbor. In this case, the neighbor is part of an autonomic network domain. 2 The hello message includes the unique device identifier (UDI) of the new device.
  • Page 6 Currently, the registrar validates the new devices based on an optional list of UDIs that is specified when configuring the registrar. The list specifies a set of devices that are allowed to join the network. Figure 3: Provisioning Registrar in an Autonomic Network The registrar maintains a database of all devices that join or fail to join the domain.
