Meaning

The output shows a list of the license usage and a list of the licenses installed on the router. Verify the following information:

Each license is present. Licenses are listed in ascending alphanumeric order by license ID.
The state of each license is permanent.

Note: A state of invalid indicates that the license key is not a valid license key. Either it was entered incorrectly or it is not valid for the specific device.
The feature for each license is the expected feature. The features enabled are listed by license. An all-inclusive license has All features listed.
All configured features have the required licenses installed. The Licenses needed column must show that no licenses are required.

Displaying License Usage

Purpose

Verify that the licenses fully cover the feature configuration on the router.

Action

From the CLI, enter the show system license usage command.

Sample Output

user@router> show system license usage

            Licenses     Licenses    Licenses    Expiry
  Feature name         used    installed      needed 
  subscriber-addr         1            0           1    29 days
  scale-subscriber        0         1000           0    permanent
  scale-l2tp              0         1000           0    permanent
  scale-mobile-ip         0         1000           0    permanent

Meaning

The output shows any licenses installed on the router and how they are used. Verify the following information:

Any configured licenses appear in the output. The output lists features in ascending alphabetical order by license name. The number of licenses appears in the third column. Verify that you have installed the appropriate number of licenses.
The number of used licenses matches the number of configured features. If a licensed feature is configured, the feature is considered used. The sample output shows that the subscriber address pooling feature is configured.
A license is installed on the router for each configured feature. For every feature configured that does not have a license, one license is needed.
For example, the sample output shows that the subscriber address feature is configured but that the license for the feature has not yet been installed. The license must be installed within the remaining grace period to be in compliance.

Displaying Installed License Keys

Purpose

Verify the license keys installed on the router.

Action

From the CLI, enter the show system license keys command.
