This read-write Integer32 sets the maximum number of tests the test plug will run within each avCnaTpConfTestLimiterInterval window, capping test throughput even though its own description text is a copy of the interval object's wording. An admin uses it together with the interval setting to put a hard ceiling on test volume so scheduled testing cannot overwhelm the device or the network path being tested. For example, setting avCnaTpConfTestLimiterMaxTests to 10 within a 60-second interval limits this test plug to at most 10 tests per minute regardless of how many the scheduler requests.
