Hi guys,
I just did the Port Security lab (Lab 4) from this page several times:
Packet Tracer 5.3 labs
It gave me 100%* for all of the configuration. Then I ran the ping tests and got the results it said I should get. However, it said that the sim was incomplete because the diagnostic tests failed. When I checked the results it says "Incorrect" for two of the tests, yet they succeed based on what the question was asking and said the result should be.
Has anyone done this lab? My conclusion is that the lab is flawed...?
