The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

When Prime NCS (WAN) discovers the devices in your network, it retrieves and stores the device configurations. When you make a change to a device configuration, Prime NCS (WAN) stores the previous version as well as the current version. Prime NCS (WAN) stores all device configuration versions.
You can perform configuration archive tasks in two places:
•Operate > Configuration Archives—Lists all configuration archives by device type, site group, or user-defined group. You can schedule archives, rollbacks, and view details of configurations.
•Operate > Device Work Center—View a specific device's archived configurations, schedule a configuration rollback, and schedule archive collections for a specific device.
