(Host or Switch) Displays configuration and state of a specified Intel® Omni-Path Host Fabric Interface (HFI) port on the local host or a remote switch.
Destination LID. Default is local port.
Destination port. Default is port with given LID. Useful to access switch ports.
HFI, numbered 1..n. Using 0 specifies that the -p port port is a system-wide port number. Default is 0.
Port, numbered 1..n. If -h hfi is 0, then port is a system-wide port number. Default is 1.
SM management key to access remote ports.
First port in system (default).
First port on HFI x.
Port y within system.
HFI x, port y.
Verbose output. Additional invocations (–v –v ...) turn on debugging, openib debugging, and libibumad debugging.
To access switch ports using this command, the -l and -m options must be given. The -l option specifies the LID of switch port 0 (the logical management port for the switch) and -m specifies the actual switch port to access. If SMA mkeys are used, the -K option is also needed. However, the Intel® Omni-Path Fabric Suite Fabric Manager does not use SMA mkeys by default, therefore this option may not be required.
