Article Detail

Description

When a router is applied with licenses and the license application is successful,
The applied licenses can be viewed by the CLI command show system licenses.
In a rare scenario, after reboot, the installed licenses will not be available to display via the CLI command show system licenses.

Symptoms

Applied licenses will not be displayed via the show command show system licenses.

Solution

When the licenses are installed on the router, the licenses will be stored under /var/db/confiig/licenses directory.
If some reason, the licenses directory was not created or licenses directory is deleted, licenses can be applied, however they will NOT sustain the router reboots.

Licenses directory can be referenced at /config
From the /config, we can notice the symlink which points to the license directory

[vrf:none] root@router:/config# ls -a1l

Licenses installed: none

Solution:
1. Login to to the RE shell as root user
2. Please add directory named licenses manually
3. Verify the presence of license directory in the path /var/db/config
4. In step 4 directory named as license should be present
5. Navigate to CLI mode
6. Add the license key via CLI command
7. Once the license has been added, Please verify the contents of /var/db/config/license by CLI command file list /var/db/config/license or navigating to the path /var/db/config/license
8. In the above command output, should notice the file license_key.lic in the license directory

Outputs from the router:

[vrf:none] root@e05-32:/var/db/config/license# pwd
