From the main menu, choose Admin > Providers.

Click .

Enter the following values for the Cisco SR-PCE provider fields:

1. Required fields:

   • Provider Name: Name of the SR-PCE provider that will be used in Cisco Crosswork Optimization Engine.

   • Credential Profile: Select the previously created Cisco SR-PCE credential profile.

   • Family: Select SR_PCE. All other options should be ignored.

   • Protocol: Select HTTP and enter 8080.

   • IP Address/ Subnet Mask: Enter the IP address (IPv4 or IPv6) and subnet mask of the server.

   • Port: Enter 8080 for the port number.

   • Provider Properties: Enter one of the following key/value pairs in the first set of fields (see About Adding Devices and Auto-Onboard Property Descriptions):

     Property Key	Value
     auto-onboard	off Note  Use this option if you plan to manually (via UI or CSV import) enter all of your network devices.
     auto-onboard	unmanaged
     auto-onboard	managed Note  This option is only supported on IPv4 deployments. If you enable this option for an IPv6 deployment, devices will still register as unmanaged in the inventory.
     device-profile	The name of a credential profile that contains SNMP credentials for all the new devices. Note  This field is necessary only if auto-onboard is set to managed or unmanaged.
     outgoing-interface	eth1 Note  You have to set this only if you want to enable Cisco Crosswork Optimization Engine access to SR-PCE via the data network interface when using the two NIC configuration.

2. Optional values:

   • Timeout: The amount of time (in seconds) to wait before timing out the connection to the SR-PCE server. The default is 30 seconds.

When you have completed entries in all of the required fields, click Save to add the SR-PCE provider.

Confirm that the SR-PCE provider shows a green Reachability status without any errors. You can also view the Events window to see if the provider has been configured correctly.

Repeat this process for each SR-PCE provider.

From the main menu, choose Admin > Providers.

Click .

Enter the following values for the Cisco NSO provider fields:

1. Required fields:

   • Provider Name: Enter a name for the provider that will be used in Cisco Crosswork Optimization Engine.

   • Credential Profile: Select the previously created Cisco NSO credential profile.

   • Family: Select NSO.

   • Device Key: Select the method that Cisco NSO uses to identify devices uniquely. This will serve as the way Cisco Crosswork Optimization Engine maps the device to Cisco NSO. Choices are: NONE, , INVENTORY_ID, or HOST_NAME.

   • Under Connection Type(s), Protocol: Select the protocol that Cisco Crosswork Optimization Engine will use to connect to the provider. NETCONF is usually preferred.

   • IP Address/Subnet Mask: Enter the IP address (IPv4 or IPv6) and subnet mask of the Cisco NSO server.

   • Port: Enter the port to use to connect to the Cisco NSO server. The default is 2022.

   • Model: Select the model (Cisco-IOS-XR, Cisco-NX-OS, or Cisco-IOS-XE) from the drop-down list and enter its associated NED driver version. Add a model for each type of device that will be used in the topology. If you have more than one, select to add another supported model.

   • Version: Enter the NED software version installed for the device model in NSO.

   For more information on fields, see Import Providers.

2. Optional values:

   • Timeout: The amount of time (in seconds) to wait before timing out the connection to the Cisco NSO server. The default is 30 seconds.

When you have completed entries in all of the required fields, click Save to add Cisco NSO as a provider.

From the main menu, choose Admin > Providers.

Click to open the Import CSV File dialog box.

If you have not already created a provider CSV file to import:

1. Click the Download sample 'Provider template (*.csv)' file link and save the CSV file template to a local storage resource.

2. Open the template using your preferred tool. Begin adding rows to the file, one row for each provider.

   Use a semicolon to separate multiple entries in the same field. Use two semicolons with no space between them to indicate that you are leaving the field blank. When you separate entries with semicolons, the order in which you enter values is important. For example, if you enter SSH;SNMP;NETCONF;TELNET in the connectivity_type field and you enter 22;161;830;23 in the connectivity_port field, the order of entry determines the mapping between the two fields:

   • SSH: port 22

   • SNMP: port 161

   • NETCONF: port 830

   • Telnet: port 23

   Field	Description	Required or Optional
   Provider Name	Enter the name for the provider that will be used in Crosswork Optimization Engine. For example: MySRPCE.	Required
   Connectivity Type	Enter the name of the protocol that Crosswork Optimization Engine will use to connect to the provider. For example: ROBOT_MSVC_TRANS_HTTP = HTTP	Required
   Connectivity IP	Enter the IP address (IPv4 or IPv6) of the provider. Note  When using an IPv6 address, please note the following: In the Properties column, do not set the auto-onboard property to auto-onboard:managed. The auto-onboard property is automatically set to unmanaged.	Required
   Connectivity Port	Enter the port number to use to connect to the provider's server.	Required
   Connectivity Timeout	Enter the amount of time (in seconds) to wait before the connection to the provider times out. The default is 30 seconds.	Optional
   Credential Profile Name	Enter the name of the credential profile that Crosswork Optimization Engine will use to connect to the provider. This profile must already exist in the system.	Required
   Provider Device Key	Enter the enum value corresponding to the key that the Cisco NSO provider uses to identify devices uniquely. This will serve as the way Crosswork Optimization Engine maps the device to the Cisco NSO provider. Valid values are: ROBOT_PROVDEVKEY_HOST_NAME—If you are using the device hostname as the device ID within NSO, this value must match the hostname that is specified for the device in the inventory. ROBOT_PROVDEVKEY_NODE_IP—Use this enum value if the NSO device identifier is the IP address for the Node IP value in the CSV file. ROBOT_PROVDEVKEY_INVENTORY_ID—Use this enum value if the inventory ID is the device identifier for NSO.	This entry is only required if you are creating or updating a Cisco NSO provider. Otherwise, leave blank.
   Family	Enter ROBOT_PROVIDER_SR_PCE or ROBOT_PROVIDER_SR_NSO. Do not choose other options as they are reserved for use by other Cisco Network Automation applications.	Required
   Model Prefix	If you are adding a Cisco NSO provider: Select the model prefix that matches the NED CLI used by the NSO server. Valid entries are: Cisco-IOS-XR, Cisco-NX-OS, Cisco-IOS-XE. For telemetry, only Cisco-IOS-XR is supported.	Required for Cisco NSO providers only
   Model Version	If you adding a Cisco NSO provider: Enter the Cisco NSO NED driver version used on the server.	Required for Cisco NSO providers only
   Properties	Enter the Cisco SR-PCE appropriate auto-onboard entries: auto-onboard:<auto-onboard-property>; device-profile:<SRPCECredentialProfileName> . For example: auto-onboard:managed;device-profile:cisco When using IPv6 connectivity, do not set auto-onboard:managed. See Add Cisco SR-PCE Providers.	This entry is only required if you are creating or updating a Cisco SR-PCE provider. Otherwise, leave blank.

   Be sure to delete the sample data rows before saving the file, or they will be imported along with the data you want. The column header row can stay, as it is ignored during import.
