To restrict licenses to particular users/groups: Macrovision’s Flexnet supports an option file with options like RESERVE, INCLUDE, EXCLUDE, GROUP, USER, etc,. Please refer the attached document for more details and Spirent.opt is an example. Follow this procedure in order to use the .opt file: 1 Place Spirent.opt file in the same directory where the license file (<filename>.lic) and license server files located. 2 If you place Spiret.opt file in other than the license server directory, modify the VENDOR line as shown here: VENDOR spirent options="C:\FlexNet\floating_lic_server\Spirent.opt" 3 Restart the license server to implement the change.
