Hello @juanvn86 . Thanks for sharing, but i think the same as @Rafael_Caixeta:
Boda works pretty fine for me too… It is free, is fast… why would I need another tool? 
I encourage you to try it:
(Boda Lite - Multivendor/Multitechnologies Network Management Tool (CM, PM and more) - #20 by Emmanuel)
It works for Huawei, Ericsson and NOKIA.
@boyan Boda has been downloaded 50k+.
Of couse, part of this are from students and other kind of people just wanting to learn the code… but i bet thousands are professionals, and can help you with this error.
So, can you please tell again details of the error you’re getting?
