Understanding the Cumulus Linux License

The Cumulus Linux license has a simple format. Managing your license keys is very easy, as you can use the same license file for all your licensed Cumulus Linux switches.

In addition, there is no need to replace the license file when you renew or purchase additional licenses.

From a technical standpoint, the license has changed as follows:

• Increased messaging volume, which is displayed on screen when you log into the switch, and is written to syslog.
• New messaging when switchd detects a missing or invalid license.  

The license format looks like this:

user@company.com|thequickbrownfoxjumpsoverthelazydog312

You manage your licenses in the Cumulus Networks customer portal.

To verify that your license is installed, run the cl-license command.

cumulus@switch:~$ cl-license
user@example.com|$ampleL1cen$et3xt

For more information on the use of cl-license, please refer to the Quick Start Guide.
