       smpquery - query InfiniBand subnet management attributes

       smpquery allows a basic subset of standard SMP  queries  including  the
       following:  node info, node description, switch info, port info. Fields
       are displayed in human readable format.


       Current supported operations and their parameters:
                      nodeinfo <addr>
                      nodedesc <addr>
                      portinfo <addr> [<portnum>]     # default port is zero
                      switchinfo <addr>
                      pkeys <addr> [<portnum>]
                      sl2vl <addr> [<portnum>]
                      vlarb <addr> [<portnum>]
                      guids <addr>

       --node-name-map <node-name-map>
              Specify a node name map.  The node name map file maps  GUIDs  to
              more  user  friendly  names.  See ibnetdiscover(8) for node name
              map file format.


       Most OpenIB diagnostics take the following common flags. The exact list
       of  supported  flags  per utility can be found in the usage message and
       can be shown using the util_name -h syntax.

       # Debugging flags

       -d      raise the IB debugging level.
               May be used several times (-ddd or -d -d -d).

       -e      show send and receive errors (timeouts and others)

       -h      show the usage message

       -v      increase the application verbosity level.
               May be used several times (-vv or -v -v -v)

       -V      show the version info.

       # Addressing flags

       -D      use directed path address arguments. The path
               is a comma separated list of out ports.
               "0"             # self port
               "0,1,2,1,4"     # out via port 1, then 2, ...

       -c      use combined route address arguments. The
               address is a combination of a LID and a direct route path.
               The LID specified is the DLID and the local LID is used
               as the DrSLID.

       -G      use GUID address argument. In most cases, it is the Port  GUID.

       -s <smlid>      use ’smlid’ as the target lid for SM/SA queries.

       # Other common flags:

       -C <ca_name>    use the specified ca_name.

       -P <ca_port>    use the specified ca_port.

       -t <timeout_ms> override the default timeout for the solicited mads.

       Multiple CA/Multiple Port Support

       When  no IB device or port is specified, the port to use is selected by
       the following criteria:

       1. the first port that is ACTIVE.

       2. if not found, the first port that is UP (physical link up).

       If a port and/or CA name is specified, the user request is attempted to
       be fulfilled, and will fail if it is not possible.


       smpquery portinfo 3 1        # portinfo by lid, with port modifier

       smpquery -G switchinfo 0x2C9000100D051 1        # switchinfo by guid

       smpquery -D nodeinfo 0       # nodeinfo by direct route

       smpquery -c nodeinfo 6 0,12  # nodeinfo by combined route
