Describes necessary prerequisites for initiating device configuration, ensuring readiness for workflow execution.
General prerequisites
-
Before configuring any device in the network, ensure that the device is validated and authenticated so that SD-WAN Manager, Cisco SD-WAN Controllers, and SD-WAN Validators recognize it as authorized in the overlay network.
-
A signed certificate must be installed on SD-WAN Manager, Cisco SD-WAN Controllers, and SD-WAN Validators to validate and authenticate them in the overlay network.
-
Obtain an authorized serial number file from Cisco, which lists the serial and chassis numbers for all routers permitted in your network. Upload this serial number file to SD-WAN Manager to validate and authenticate the routers.
Variables spreadsheet
Feature templates often include variables. To ensure SD-WAN Manager populates these variables with actual values when attaching a device template to a device, create an Excel spreadsheet containing the variable values for each device, and save it in CSV format.
In the spreadsheet, the header row contains the variable name and each row after that corresponds to a device, defining the values of the variables. The first three columns in the spreadsheet must be the following, in this order:
-
csv-deviceId—Serial number of the device (used to uniquely identify the device). For routers, you receive the serial numbers in the authorized serial number file sent to you from Cisco. For other devices, the serial number is included in the signed certificate you receive from Symantec or from your root CA.
-
csv-deviceIP—System IP address of the device (used to populate the system ip address command).
-
csv-host-name—Hostname of the device (used to populate the system hostname command).
You can create a single spreadsheet for all devices in the overlay network—Cisco Catalyst SD-WAN Controllers, SD-WAN Validators, and routers. You do not need to specify values for all variables for all devices.SD-WAN Validator
