is now running. You can use either the “show boot system” command or the “dir” command.

Reverting to a Previous Image
In the event that you need to downgrade to a previous version of code, you can do so by
completing the following steps as described in this chapter.
1. Save your running configuration with the save config command.
2. Make a copy of the current configuration with the show config outfile configs/filename
command. Use the dir command to confirm that the file was created.
3. If desired, copy the file to a remote TFTP server with the copy command:
copy configs/filename tftp://server_ipaddr/filename
4. Load your previous version of code on the device, as described in “Downloading a Firmware
Image” (page 3-27).
5. Set this older version of code to be the boot code with the set boot system command (page 3-
31). When the system asks if you want to reset the device, specify no (n).
6. Reload the saved configuration onto the device with the configure command, described on
page 3-40.
7. Reboot the system using the reset command (page 3-47).
Caution: Before reverting to a previous image, always back up your configuration by saving it to a
file (show config outfile on page 3-39). You can then copy the file to a remote location (copy on
page 3-41).
Note: You will not be able to peform these steps remotely unless you have remote console support.
Caution: If you do not follow the steps above, you may lose remote connectivity to the switch.
