Clavister cOS Core licenses have a throughput limit parameter. Does this restriction include traffic that is flowing through a loopback interface pair? An example would be if we have a license that has a 200 Mbit throughout limit and we send 50 Mbits in and out of a loopback pair, does that then use 100 Mbit of the license limit?


No, license throughput restrictions do not apply to loopback interfaces. If throughput restrictions did apply, that would severely limit the usefulness of loopback interfaces.
