Peter,
"we are planning to add one more step to the whole process of getting ports into UDT which would allow import from NPM without a need of discovery."
This doesn't help us. We monitor only uplink and selective ports in NPM. We monitor all ports with UDT. The UDT port discovery worked just fine pre-3.1. Why not expand the "one more step" to provide options to select "import ports from NPM" and "perform port discovery now" (pre-3.1 method)?
