Different software has different names/features, but it comes down to vertex normals.
If your model has no vertex normals, or they are merged/welded, we will smooth at a 'crease angle' of 45°. If you have 'unwelded' vertices, you'll see every facet.
In Maya, I think you'll want to set Shading to Flat Shade All so you can see the effect of normals without Maya's native viewport smoothing. Then, find Mesh... → Set Normal Angle...
The angle you set here is the 'crease angle'. Edges with a smaller angle than that will be smoothed. So, 0 will be complete faceted, and 180 will smooth everything. Here are some examples straight out of Maya:

I hope that helps!
