I have just started experimenting with UDT and I see it has potential, but one snag I am encountering is that some virtual chassis will not show any information at all for the ports imported into UDT. When importing the device, it connects via SNMP and shows all ports, but data is never updated/included (MAC/VLAN etc..).
I am already running NPM 10.2 /NCM for monitoring these devices without any problems.
