226
227 <para>Zero-Touch Provisioning (ZTP) is an alternative to Manual
228 configuration. ZTP refers to the process by which, when a device starts up
229 for the first time, its initial configuration is pushed down by an
230 external management system, so that it is setup for proper operation
231 without additional manual intervention by an operator.</para>
232
233 <para>A variety of operations can occur as part of ZTP such as initial
234 device setup, configuration of managed objects, etc. The goal is to set up
235 a device to the maximum possible extent without forcing an operator to be
236 physically present (initially) to manage the device.</para>
237
238 <para>In order to create a static configuration supporting ZTP, the uCPE
239 Manager user needs to identify the <literal>Device ID</literal> of the
240 machine running NFV Access.</para>
241
242 <para>During the automatic installation process when the
243 <literal>Automatic install</literal> step is reached, enter the option
244 menu <literal>Customize kernel parameters</literal> and set the
245 <literal>uCPE Manager IP address</literal>. Please check <xref
246 linkend="install_ena_stick" />, for how to set the uCPE Manager IP address
247 at boot time. The Device ID will be listed in the installer under the
248 <literal>Customize kernel parameters</literal> menu.</para>
249
250 <para>With the address parameter set, run
251 <literal>list_deviceID.sh</literal> after NFV Access is installed and
252 booted, to get the device ID of the uCPE device.</para>
253
254 <note>
255 <para>It is possible to let NFV Access know the uCPE Manager IP address
256 at run-time by setting <literal>vcpemgr=&lt;IP&gt;</literal> as a kernel
257 boot parameter in the grub configuration file. Reboot is required after
258 this update.</para>
259
260 <para>This step needs to be done each time the uCPE Manager host changes
261 its IP address.</para>
262 </note>
263
264 <para>An offline configuration can be prepared in advance for the uCPE
265 Manager to setup the infrastructure on the device.</para>

270 <para>The uCPE Manager must be configured to bring the uCPE device under
271 management. This is done by selecting <literal>Device Calls
272 Home</literal> checkbox when adding a device. When Device Calls Home
273 checkbox is checked, the device will initiate a connection by opening a
274 socket to the uCPE Manager for NETCONF traffic (over SSH), while the
275 uCPE Manager waits for device connection.</para>

351
352 <para>As the acting vnf manager, the uCPE Manager is responsible for
353 handling the life-cycles of VNFs that are instantiated and run on the
354 various uCPE devices. The vnf manager module is written so as to be able
355 to manage multiple VNF types. Along with it is provided a generic
356 infrastructure to allow the end-user to introduce new VNF types
357 dynamically into the system. This allows for third-party VNFs to be added
358 over time to an existing network infrastructure without having to perform
359 an expensive upgrade of the vnf manager itself.</para>
360
361 <para>The process of VNF Onboarding consists of providing the system with
362 sufficient information and resources related to the VNF such that it can
363 instantiate a flavour of the VNF on the uCPE device, configure and scale
364 it as appropriate, heal and upgrade it when necessary and tear it down at
365 the right moment.</para>

413 <para>As the acting vnf manager, the uCPE Manager is responsible for
414 handling the life-cycles of VNFs that are instantiated and run on the
415 various uCPE devices. The vnf manager module is written so as to be able
416 to manage multiple VNF types. Along with it is provided a generic
417 infrastructure to allow the end-user to introduce new VNF types
418 dynamically into the system. This allows for third-party VNFs to be added
419 over time to an existing network infrastructure without having to perform
420 an expensive upgrade of the vnf manager itself.</para>
421
422 <para>The process of VNF Onboarding consists of providing the system with
423 sufficient information and resources related to the VNF such that it can
