CLI Templates for Cisco XE SD-WAN Routers

The CLI Templates for Cisco XE SD-WAN Routers features allows you to configure intent-based CLI templates for Cisco XE SD-WAN routers using vManage. Intent-based CLI template refer to the command line interface configuration that are based on the vEdge device syntax. Using CLI templates, vManage enables pushing vEdge syntax-based commands to Cisco XE SD-WAN Routers in Cisco IOS XE Syntax.

Using vManage CLI templates significantly reduces the effort to configure feature templates.

Benefits of CLI Templates

  • You can reuse any Cisco vEdge-specific vManage feature templates for Cisco IOS XE Routers. When you create a device template using Cisco XE SDWAN Feature Templates, vManage displays the intent-based configuration (vEdge CLI syntax) and the corresponding device-based (Cisco XE SDWAN Routers) configuration. You can examine the intent-based configuration and repurpose that to create a separate CLI template for XE SDWAN routers.

  • You can make multiple changes to a CLI template in a single edit.

  • You can use a single configuration across multiple devices of the same device models. Variables can be used for rapid bulk configuration rollout with unique per-device settings. Common configurations like system-IP, site-id, hostname, IP addresses, and so on, can be defined as editable variables in the template and the same template can be attached to multiple devices.

  • You can define custom length for variables in CLI Templates.

  • You can use any existing IOS-XE device intent configuration as input for CLI template.

  • Content of a CLI template can be used across multiple IOS-XE device types (common CLIs like VPN, VPN interface, BGP, OSPF and so on).

Configuring CLI Templates in vManage

  1. In vManage, select Configuration ► Templates.

  2. In the Device tab, click Create Template.

  3. From the Create Template drop-down, select CLI Template.

  4. From the Device Model drop-down, select the type of device for which you are creating the template.

  5. In the Template Name field, enter a name for the template. The name can be up to 128 characters and can contain only alphanumeric characters.

  6. In the Template Description field, enter a description of the template. The description can be up to 2048 characters and can contain only alphanumeric characters.

  7. The configuration of the CLI template must be intent-based. You can upload a configuration file using the Select a File field or copy and paste the CLI configuration. Following is an example of an intent-based CLI with variables. 

    system

   host-name {{hostname}} 
   system-ip {{system_ip}} 
   domain-id 1

   site-id {{site_id}} 
   port-offset           1
   admin-tech-on-failure
   organization-name "XYZ"
   logging 
    disk 
     enable 
! !

    These variables can be filled in device variables page per device after attaching the template. Values can be entered manually or can be uploaded via a csv file.

  8. To save the feature template, click Add.


Note

See the Attach Devices to a Device Template section in this topic to know more about attaching a device to a template and reusing a template for multiple devices of the same device model.
