Device

Devices represent individual IOS-XR network devices that will be configured and managed. Each device is identified by a unique name and requires a host IP for connectivity.

Device configurations have the highest precedence in the configuration hierarchy, allowing you to override global and device group settings for specific devices. This provides fine-grained control while maintaining consistency across your network infrastructure.

Key device attributes:

• name: Unique identifier for the device
• host: IP for device connectivity (gNMI), optionally a port can be added with :12345. The default port is 57400
• managed: Boolean flag to temporarily exclude devices from configuration (useful for maintenance)
• device_groups: List of device groups this device belongs to
• variables: Device-specific variables that override group and global variables
• configuration: Device-specific configuration that takes highest precedence

The managed attribute can be set to false to temporarily skip a device during deployment, which is useful for maintenance windows or staged rollouts.
