Supported Fabric Types


The UFM Cable Validation Tool is compatible with the following fabric types:

Fabric Type

Description

InfiniBand

Supported on MLNX-OS Switches with NDR and HDR port speeds

XDR

Supported on NVOS Q3400-RA Switches with XDR port speed (Does not support link flap detection)

Ethernet

Supported on Cumulus Switches and Ethernet Hosts

NVLink

  • Supported on NVOS Switches and compute nodes of GB200/GB300 rack types: 36x2, 36x1, and 72x1.

  • Supported on internal NVLink links in the rack

  • Hosts with external links as Ethernet or IB 

  • The external InfiniBand links will report BER status, but neighboring information will need to be monitored from the neighboring switch side only.
