Calculate and Verify the MD5 Checksum for a File on the Switch

Perform this procedure to verify that the software files are downloaded properly to the switch. The MD5 checksum for each release is available from the Extreme Networks Support portal.

Before you begin

Download the MD5 checksum to an intermediate workstation or server where you can open and view the contents.
Download the image file to the switch.

About this task

Calculate and verify the MD5 checksum after you download software files.

Procedure

To enter User EXEC mode, log on to the switch.
View the list of files:

ls *.voss
Calculate the MD5 checksum for the file:

file-checksum md5 WORD<1-99>
Compare the number generated for the file on the switch with the number that displays in the MD5 checksum on the workstation or server. Ensure that the MD5 checksum of the software suite matches the system output generated from calculating the MD5 checksum from the downloaded file.

Example

View the contents of the MD5 checksum on the workstation or server:
