Software Integrity Verification
To verify the integrity of the software image you have from Cisco, you can validate the SHA512 checksum information against the checksum identified by Cisco for the software.
Image checksum information is available through Cisco.com Software Download Details. To find the checksum, hover the mouse pointer over the software image you have downloaded.
At the bottom you find the SHA512 checksum, if you do not see the whole checksum you can expand it by pressing the "..." at the end.
To validate the information, calculate a SHA512 checksum using the information in the following table and verify that it matches with the one provided on the software download page.
To calculate a SHA512 checksum on your local desktop, refer to the following table please.

Operating System |
SHA512 Checksum Calculation Command Examples |
|---|---|
|
Microsoft Windows |
Open a command line window and type the following command: |
|
Apple MAC |

|
NOTES: <filename> is the name of the file. <extension> is the file extension (e.g. .zip or .tgz). |

If the SHA512 checksum matches, you can be sure that no one has tampered with the software image, or the image has not been corrupted during download.
If the SHA512 checksum does not match, we advise you to not attempt upgrading any systems with the corrupted software image. Download the software again and verify the SHA512 checksum again. If there is a constant mismatch, please open a case with the Cisco Technical Assistance Center.
