About network span actions
Span actions are interaction "types" between TrueSight Network Automation and the devices being managed. Span actions target a single device or multiple devices via multiple device selection, groups, realms, or the entire network. These target devices are referred to as the "span" and the type of interaction selected is the "action" to be performed. TrueSight Network Automation supports actions on network spans such as Snapshot, Deploy to Stored, Commit, and Reboot. Actions are initiated by users, web services clients, and policies. A single job might execute one or more of the following actions:
Assigns a Target configuration to a device. Once assigned, the Target configuration can be modified, audited for compliance to standards (that is, assigned Rules) and merged/restored to a device.
Copies the device's Running configuration to the Startup configuration to ensure changes are applied at restart (for example, for Cisco performs a
Displays the compliance status information from the archived compliance data recorded during prior Snapshot and Refresh Device Status actions.
Custom actions are scripts written by the site to perform custom device interaction. The scripts are written by using the TrueSight Network Automation XML scripting language, which is easy to learn and hides complex I/O operations so you can focus on the task at hand. For details, see Developing a custom action adapter. Custom actions are most commonly used to:
Deploy OS Image
Deploys an OS binary image to a device.
Deploy to Active
Makes configuration changes to the Running configuration. Deploy to Active is used to:
Note: Seefor more information about when it is best to use template, rule, or Target configuration to make configuration changes.
TrueSight Network Automation supports the following types of Deploy to Active operations:
Deploy to Stored
Copies a configuration to a device's Startup configuration.
Mark as Trusted
Designates a device's trusted configuration or desired state for discrepancy monitoring, reporting, and notifications.
Restarts a device. This causes a device to invoke a prior configuration change or a newly loaded OS image.
Refresh Device Status
Refreshes the compliance violation, discrepancy status, configuration profiled dynamic fields, and offline status for a network span. If you modify a non-CAP dynamic field with auto-grouping enabled, you have to run this action to refresh the status. For information about when to use this action see Testing rules, Understanding when to refresh, and T.
|Remediate||Makes corrections to the in-violation compliance rules, based on the corrective actions of each rule.|
Validates the syntax of a CLI script without changing the device's configuration. Used when testing new templates or rules.
Copies the Running and Startup configuration from the device to the configuration archive. The configuration files are only added to the archive when changes are detected.
Snapshot OS Image
Copies the current OS binary image from the device to the OS image library.
Launches a Telnet/SSH session with a device where TrueSight Network Automation proxies the session; logs the command/response interaction in the job transcript, and shows a side-by-side difference report of all the changes made during the session.
