The subnet mask column for all devices is always 0.0.0.0. The column uses attribute 0x12dbc which is a calculated attribute. Is there a reason why this is always 0.0.0.0? This extraction of this value through the REST API is required for a few projects. For most of the devices, we can use 0x100af.
There is an issue with the normalization of the data.
Release : 10.4.1
Component : Spectrum Core / SpectroSERVER
For most of the devices use external attribute ipAdEntNetMask 0x100af.
This will be resolved in a future release of NetOps via DE467546
