To use the following features on a Services Router, you must purchase a license. (See Step 4. Adding Licenses with the CLI or Step 2. Configuring Basic Settings with J-Web Quick Configuration.)
For these features, the presence on the router of the appropriate software license keys (passwords) determines whether you can use the feature. You must install and properly configure the license. The router allows you to commit a configuration with a feature that requires a license even if the license is not present, but you are prohibited from actually using the feature.
