Hi arunhsc,
This community is dedicated to Add-ons created for NI VeriStand only.Your question seems to refer to basic functionality of NI VeriStand and those questions are usually addressed in the Developer Zone NI VeriStand Discussion Forums.
To briefly address your question, what kind of ports are you referring to? The inports, outports, parameters, signals or a combination of all 4 types? How many ports do you see?
In the past we saw one incidence where not all of the parameters were imported from a customer's model. However they were using more than 9000 parameters in their model. This has since been fixed in NI VeriStand 2011.
For further assistance, I would recommend that you post your question on the Developer Zone NI VeriStand Discussion Forums.
