NVIDIA UFM Enterprise User Manual

Ports Window

Provides a list of all ports in UFM. 

Important: For InfiniBand network devices that support port labels (e.g., XDR, NDR switches, HCAs of type ConnectX-6 or later), the port dname will include port labels (e.g., "dname": "1/3/1"). For other types, only the port number will be displayed.

    • Active ports can be filtered by the following states: Active, Armed, and

Clicking "Cable Information" opens up a window which provides data on operational, module, and troubleshooting information as shown in the following:

UFM supports showing extended cable information for XDR aggregated ports.

The flags high_ber_ports_auto_isolation must be configured in the gv.cfg file to enable this feature.

For each port discovered as a high-BER port, a new event is triggered in the Events table.

Marking the high-BER port as unhealthy suppresses all events and notifications related to the auto-isolated port.
