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.

Caution: Before reverting to a previous image, always back up your configuration by saving it to a file (show config outfile on page 3-43). You can then copy the file to a remote location (copy on page 3-45).

Note: You will not be able to peform these steps remotely unless you have remote console support.

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 tftp://configs/filename server_ipaddr/path and filename

4.Load your previous version of code on the device, as described in “Downloading a Firmware Image” (page 3‐32).

5.Set this older version of code to be the boot code with the set boot system command (page 3‐ 36). 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 3‐44.
