Correct, the 9216i and 9222i should come with the license installed for the built in GE ports. If you add an additional module to slot 1 on either, or to a 95xx platform, then you need the license for that module.
There is a 120 day grace period for the FCIP license. It counts down to 0 days as long as FCIP is enabled. Once it hits 0 days left, FCIP will not work.
TTL of 1 could be used for production environments to by pass the license where the GE ports are on the same subnet.
