About configurations and trails

This topic provides information about configurations and trails, and how they are used by TrueSight Network Automation.

Configuration

A configuration refers to a configuration file that defines the set of operating parameters for controlling the behavior or functioning of a device. The following table describes the standard configurations used by TrueSight Network Automation:

Configuration

Description

Current RunningThe current operating parameters resident in the device. These are the settings the device is actively using to perform its routing, switching, and/or security functions.
Current StartupThe operating parameters stored in the device that take effect when the device is booted.

Historical Running/Startup

Past Running/Startup or other configuration files that have been superseded by the current Running or Startup or other current configuration.

Trusted Running

For revision control, the current or a historical Running configuration designated as a stable, production baseline by the user. There is only one Trusted Running configuration per device.

Trusted Startup

For revision control, the current or a historical Startup configuration designated as a stable, production baseline by the user. There is only one Trusted Startup configuration per device.

TSNA Device Attributes

TrueSight Network Automation's internal device settings, containing the user-editable attributes of a device (all the attributes from the device edit page).

Target

You can assign a Target configuration to each device containing base or ideal or desirable settings. Once assigned, the Target configuration can be modified and merged or restored to a device.

Template

One or more CLI commands that are restored to the device's Startup configuration or merged with the device's Running configuration.

Note

Only Running and Startup configurations support Trusted configurations. Devices that do not support Startup configurations do not have a Startup, Trusted Startup, or Historical Startup configuration.

Configurations are either in ASCII or binary format. Encoded binary configurations support a limited set of configuration actions. Some devices allow decoding of their binary configurations for display purposes. TrueSight Network Automation performs this decoding automatically.

The following figure shows configuration of a Cisco device that is stored in ASCII format:

Trail

A trail refers to a chronological sequence of configurations of the same kind, archived over time, representing the history of changes detected by TrueSight Network Automation. The newest configuration within a given trail is known as the current configuration. Older configurations are known as historical configurations.

Examples of trails: Startup, Running, and other arbitrary configuration files that are required to capture a complete snapshot of a device (such as a vlan.dat file for Cisco IOS).

TrueSight Network Automation includes, out-of-the-box, all of the trails necessary for the complete set of device types that it supports.
