NVIDIA Fabric Manager manages the NVLink and NVSwitch fabric on DGX and HGX systems:

Configures NVSwitch routing tables
Enables GPU-to-GPU communication across the NVLink fabric
Required for multi-GPU training on DGX systems

Critical: Starting with DCGM 2.0, Fabric Manager is not bundled with DCGM. It must be installed separately. The Fabric Manager version must match the driver version.
