Cisco IOS Auto-Upgrade Manager
Cisco IOS
®
Auto-Upgrade Manager automates the process of upgrading Cisco IOS Software versions on
Cisco
®
1800, 2800, and 3800 Series Integrated Services Routers directly from the console without
additional management software. Whether for a single device or multiple devices, Cisco IOS Auto-
Upgrade Manager guides the user through the process of downloading the software to the router and
scheduling the upgrade with easy-to-use, interactive mode prompts. More advanced users can take
advantage of the Cisco IOS Auto-Upgrade Manager “single-line” command to initiate the process. Either
way, Cisco IOS Auto-Upgrade Manager can help reduce the cost of upgrading systems by streamlining
the process to perform Cisco IOS Software upgrades by engineers of varying skill levels.
Product Overview
Cisco IOS Auto-Upgrade Manager manages and simplifies the process of upgrading (or downgrading) Cisco IOS
Software versions on Cisco 1800, 2800, and 3800 Series Integrated Services Routers. The user interface to Cisco
IOS Auto-Upgrade Manager, which is through the console, can be a series of easy-to-use, conversational mode
prompts; a single-line command; or several nonprompted commands, depending on the user’s familiarity with
upgrading software versions. Cisco IOS Auto-Upgrade Manager loads the new software version from Cisco or any
FTP or Trivial File Transport Protocol (TFTP) server the user specifies. The application checks to ensure that the
router has enough free memory on secondary storage for the software image, and if not, cleans up secondary
storage to free space for the image. After validating the image, it schedules the upgrade, incorporating capabilities
introduced with Warm Upgrade to minimize downtime and provide automatic rollback if the new version fails to
initialize. Cisco IOS Auto-Upgrade Manager can send a status e-mail on completion, and the application keeps a file
of any old configuration lines that are no longer valid.
The Challenge
Users upgrade Cisco IOS Software periodically for a variety of reasons: They may need new features or functions to
implement new services, they may wish to standardize software versions in their company network to ease support,
or they may find a security vulnerability or software bug that can be eliminated with a later version of Cisco IOS
Software. Whatever the reason for the upgrade, when the new version is identified, the network engineer must find
the software version, download it to a server, transfer it to the router or switch, and then schedule the upgrade and
manually reload the device. Cisco provides management software that can help with that process, such as
CiscoWorks, but that software may not always be available to the person performing the upgrade. Although
upgrading Cisco IOS Software manually is not difficult, users unfamiliar with the process may still be intimidated.
More experienced users may find the process cumbersome - especially if they have a large number of systems
to upgrade.
The Solution: Cisco IOS Auto-Upgrade Manager
Cisco IOS Auto-Upgrade Manager simplifies upgrading Cisco IOS Software versions on Cisco 1800, 2800, and 3800
Series Integrated Services Routers for both novices and experienced network engineers. When in enable mode,
novice users need only to issue a simple command, upgrade automatic to begin an interactive script that guides
them through the process of downloading the new software and performing the upgrade. More experienced users
can avoid the detailed script and issue either a series of commands to step through the process or a single
command with all the required information to quickly load the new software and perform the upgrade (refer to the
