Calculate and Verify the MD5 Checksum for a File on a Client Workstation

Perform this procedure on a Unix or Linux machine to verify that the software files downloaded properly. The MD5 checksum for each release is available on the Extreme Networks Support website.

About this task

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

Procedure

Calculate the MD5 checksum of the downloaded file:

$ /usr/bin/md5sum <downloaded software-filename>

Typically, downloaded software files are in the form of compressed Unix file archives (.tgz files) or .voss files.
Verify the MD5 checksum of the software suite:

$ more <md5–checksum output file>
Compare the output that appears on the screen. Ensure that the MD5 checksum of the software suite matches the system output generated from calculating the MD5 checksum from the downloaded file.

Example

Calculate the MD5 checksum of the downloaded file:

$ /usr/bin/md5sum VSP4K.4.0.40.0.tgz

02c7ee0570a414becf8ebb928b398f51 VSP4K.4.0.40.0.tgz

View the MD5 checksum of the software suite:

$ more VSP4K.4.0.40.0.md5
