Maintenance: IOS upgrade/downgrade with archive download-sw command

Reference:Catalyst 3750 Switch Cisco IOS Commands

archive download-sw and IOS tar image
Upgrading or downgrading of Cisco IOS has been made easier with archive download-sw command, this command downloads and unpacks the IOS tar file and install them into their respective directories in the flash. No longer you need to do a delete of IOS then upload the IOS, the archive command does all the thing for you.

Without option and /safe option
archive download-sw command has several options, if none is specified the default option is /overwrite, this option means to overwrite everything in the flash with the downloaded IOS tar image.

The old IOS was deleted and replaced with the new one.

/allow-feature-upgrade

If you are updating firmware that is a different feature set you need to use this option otherwise the installation process will produce an error.

/allow-feature-upgradeis not really an upgrade, if your switch is using ipservices image but for some reason you need ipbase image instead you can use this option to download the ipbase and install.

As shown above, the switch feature set is downgraded from ipservices feature set to ipbase feature set.

/imageonly option

/imageonly is the option that download only the bin image and not the html files. If the old IOS has html, as soon as the new IOS bin is downloaded the old IOS bin image and the html are deleted.

This is the original output before doing archive download-sw /imageonly

To remove the directory use the delete /recursive /force command.

/safe option

The /safe option waits for the new IOS to be downloaded successfully before deleting the old IOS, the old IOS is deleted as soon as the new IOS is downloaded.
