Introduction
This document provides instructions on how to revert the software image on the Cisco VPN 3000 Concentrator. These instructions can be used to toggle the software image back to another version of code on the concentrator.
The VPN Concentrator has two locations for storing image files: the active location, which stores the image currently running on the system; and the backup location. Updating the image overwrites the stored image file in the backup location and makes it the active location for the next reboot.
