This is actually a limitation on product side that we could not add MSE as the network device in Prime.
Just wanted to check if the limitation continues in latest codes as well.
Its more like my comprehension about the product was wrong. MSE cannot be added as a Network device since there is not even an option to define snmp community on MSE.
Also the way to add CMX and MSE in CPI belongs at completely different location : Services --> Mobility Service --> MSE /CMX and then we need to add the Device IP address and the admin credentials.
Since the communication between MSE and CMX with CPI needs to be over SOAP/ XML, having them added as network devices to communicate just over SNMP will not even make any sense.
