We sometimes observe failures in the test due to too large discrepancy between the measured and expected ratios. For example:
TEST: ECMP [FAIL] Too large discrepancy between expected and measured ratios INFO: Expected ratio 1.00 Measured ratio 1.11 Fix this by allowing an up to 15% deviation between both ratios. Another possibility is to increase the number of generated flows, but this will prolong the execution time of the test, which is already quite high.
