Configuring Fabric Interface

In most common cases, UFM is run in management mode; the UFM SM manages the InfiniBand fabric. In such cases, the only mandatory configuration is setting the fabric_interface parameter.

The fabric interface should be set to one of the InfiniBand IPoIB interfaces, which connect the UFM/SM to the fabric: 

fabric_interface = ib0

  • By default, fabric_interface is set to ib0

  • fabric_interface must be up and running before UFM startup, otherwise, UFM will not be able to run


For additional configuration options, please refer to the UFM Enterprise Additional Configurations.
