Ports Window

Provides a list of all ports in UFM. 

Important: For InfiniBand network devices that support port labels (e.g., XDR, NDR/HDR switches, HCAs of type ConnectX-6 or later), the port dname will include the port label from sysinfo when available (e.g., "dname": "1/3/1"). For NDR split-ready switches, the label reflects the switch UI port presentation: a non-split port is shown with the base connector label, for example "dname": "9/1", while a split port includes the split index, for example "dname": "9/1/1" or "dname": "9/1/2". For other device types, only the port number is displayed.

All enable/disable actions on managed switches’ ports are persistent. Thus, if a managed switch port is disabled, the port remains disabled even when rebooting the switch.

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.

Physical Grade and Eye Opening Information 

Eye opening information contains the following data:

  • Physical Grade: [Grade0, Grade1, Grade2, Grade3] 

  • Height Eye Opening [mV]: [Height0, Height1, Height2, Height3] 

  • Phase Eye Opening [psec]: [Phase0, Phase1, Phase2, Phase3]

A new tab called Eye Information was added under cable information modal in ports table.

Auto-isolation of High-BER Ports

The High BER Ports tab lists all high-BER ports in the fabric.

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.
