Overview

Junos® Snapshot Anministrator enables you to capture and audit runtime environment snapshots of your networked devices running the Junos operating system (Junos OS).

Junos Snapshot Administrator can perform the following functions on either a single device or list of devices running Junos OS:

• Take a snapshot of the runtime environment on a device.
• Compare two snapshots.
• Audit a device’s runtime environment against predefined criteria.

For example, prior to a software or hardware upgrade on a device, you can take a pre-install and post-install snapshot of the device and then compare the two snapshots. You can then review the operational changes on the device and validate these changes from a list of expected changes.

To be successful in using Junos Snapshot Administrator, you need a basic understanding of Junos OS operational mode command output in an XML format. You also need to be familiar with XPath expressions.
