Usage Guidelines
Use the /allow-feature-upgrade option to allow installation of an image with a different feature set, for
example, upgrading from the IP base feature set to the IP services feature.
You can use the archive download-sw /directory command to specify a directory just once, followed
by a tar file or list of tar files to be downloaded, instead of specifying complete paths with each tar file.
For example, in a mixed hardware stack, you can enter archive download-sw /directory
tftp://10.1.1.10/ c3750-ipservices-tar.122-35.SE.tar c3750e-universal-tar.122-35.SE2.tar
The /imageonly option removes the HTML files for the existing image if the existing image is being
removed or replaced. Only the Cisco IOS image (without the HTML files) is downloaded.
Using the /safe or /leave-old-sw option can cause the new image download to fail if there is insufficient
flash memory. If leaving the software in place prevents the new image from fitting in flash memory due
to space constraints, an error results.
If you used the /leave-old-sw option and did not overwrite the old image when you downloaded the new
one, you can remove the old image by using the delete privileged EXEC command. For more
information, see the
Use the /no-version-check option if you want to download an image that has a different stack protocol
version than the one existing on the switch stack. You must use this option with the /destination-system
option to specify the specific stack member to be upgraded with the image.
Use the /no-version-check option with care. All stack members, including the stack master, must have
Note
the same stack protocol version to be in the same switch stack. This option allows an image to be
downloaded without first confirming the compatibility of its stack protocol version with the version of
the switch stack.
You can upgrade more than one specific stack member by repeating the /destination-system option in
the command for each stack member to be upgraded.
Use the /overwrite option to overwrite the image on the flash device with the downloaded one.
If you specify the command without the /overwrite option, the download algorithm verifies that the new
image is not the same as the one on the switch flash device or is not running on any stack members. If
the images are the same, the download does not occur. If the images are different, the old image is
deleted, and the new one is downloaded.
After downloading a new image, enter the reload privileged EXEC command to begin using the new
image, or specify the /reload or /force-reload option in the archive download-sw command.
If you use the archive download-sw command on a Catalyst 3560-X or on a Catalyst 3750-X switch or
switch stack (including a mixed stack), after the switch reload and while the links are still shut down,
the MCU ucode is upgraded (if necessary). If you use the /force-ucode-reload option, the system
performs the ucode upgrade before the reload, which reduces network downtime. When you enter the
/force-ucode-reload option, you see a message explaining the behavior, requiring you to enter yes to
continue.
Use the /directory option to specify a directory for the images.
