Downgrading from a Higher Release
The procedure to downgrade the switch is identical to a switch upgrade, except that the image files to be
loaded are for an earlier release than the image currently running on the switch.
Prior to downgrading to a specific release, check the release notes for the current release installed on the
switch, to ensure that your hardware is compatible with the specific release. There are special caveats you
must be aware of before you downgrade the switch software to a 4.0(0)-based release. See the Cisco Nexus
release notes for your device for details.
Note
SUMMARY STEPS
1.
Locate the image files you will use for the downgrade by entering the dir bootflash: command.
2.
Install the new images.
3.
After the switch completes the installation, log in and verify that the switch is running the required software
version.
DETAILED STEPS
Step 1
Locate the image files you will use for the downgrade by entering the dir bootflash: command.
If the image files are not stored on the bootflash memory, download the files from Cisco.com:
a)
Log in to Cisco.com to access the Software Download Center. To log in to Cisco.com, go to the URL http://
www.cisco.com/ and click Log In at the top of the page. Enter your Cisco username and password.
Unregistered Cisco.com users cannot access the links provided in this document.Note
b)
Access the Software Download Center using this URL: http://www.cisco.com/cisco/web/download/index.html
c) Navigate to the software downloads for Cisco Nexus Series switches.
You see links to the download images for the switch.
d) Read the release notes for the related image file then select and download the kickstart and system software files to
a local server
e) Ensure that the required space is available in the bootflash: directory for the image file(s) to be copied.
We recommend that you keep the kickstart and system image files for at least one previous software
release to use if the new image files do not load successfully.
