Upgrading the Switch Software

Finding the Software Version and Feature Set

The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release number. The files necessary for web management are contained in a subdirectory. The image is stored on the system board flash device (flash:).

You can use the show version privileged EXEC command to see the software version that is running on your switch.

note.gif

Noteblank.gif Although the show version output always shows the software image running on the switch, the model name shown at the end of this display is the factory configuration and does not change if you upgrade the software license.

You can also use the dir filesystem : privileged EXEC command to see the directory names of other software images that you might have stored in flash memory.

Viewing the Software Image Upgrade History

Starting Release 15.2(7)E3, you can view the history of software image upgrades performed on the Cisco Catalyst 3560-CX devices, using the show archive sw-upgrade history command. This command displays the image name, version, upgrade method and timeline for each upgrade that is done through Auto Install, PnP, archive CLI, or HTTP methods.

Manual upgrades done through TFTP of tar files or binary files are not displayed.

If you have booted the Cisco IOS software, wait for ten minutes before using this command. This is because the software takes time to initialize after a boot.

Note that the show archive sw-upgrade history command displays the records of only the first 100 successful upgrades or downgrades (performed through Auto Install, PnP, archive CLI, or HTTP methods).

Software Image

If you have a service support contract and order a software license or if you order a switch, you receive the universal software image and a specific software license.
