Understanding Commuter Licensing
Commuter licensing uses up the same license tokens as other types of licensing. If you want to restrict the percentage of license tokens on a specific license server that can be used by commuter licensing authorizations, use the -com option when you start the license server. For more details we suggest you to read through License Server - Commonly Used Variables.
This makes sure that commuter licensing does not use up all of the license tokens needed by other users of the application on the network.
