Getting Started with a New Device
After you have replaced the device in RMA state with a new device,
The Dynamic Host Configuration Protocol (DHCP) server allots an IP address to the new device.
The Contrail Networking Controller then discovers the temporary IP address of the new device from the DHCP leases table by using the serial number of the new device.
The Contrail Networking Controller pushes the initial configuration, including the old device’s management IP address, to the new device.
The Contrail Networking Controller communicates with the device using the old IP address.
The new serial number and MAC address are saved in the
physical_routerobject in the database.
The new device image is upgraded.
With Contrail Networking Release 1908, the new device is upgraded to the device image version specified (in the OS Version field) during the initial zero-touch-provisioning onboarding process. For more information, see the Provisioning Option - New Fabric section of the Create a Fabric topic.
Finally, the Contrail Networking Controller pushes the saved underlay and overlay configuration to the new device. Any configuration changes made while the device was in RMA state will also be pushed to the new device.
