Displaying License Usage

Purpose

Meaning

The output shows a list of the licenses installed on the device and how they are used. Verify the following information:

• Each license is present. Features are listed in ascending alphanumeric order by license name. The number of licenses is shown in the third column. Verify that the appropriate number of licenses are installed.
• 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 BGP route reflection feature is configured.
• A license is installed on the device 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 user has configured the J-Flow traffic analysys feature but has not purchased the license for it. An additional license is required to be in compliance with license agreements.

• The expiration information for the license is correct. For JUNOS software with enhanced services, licenses can be either permanent or valid until a specified date.
