       (Switch) Encapsulates the capabilities for link analysis. Additionally, this tool includes
       cable and fabric topology  verification  capabilities.  This  tool  is  built  on  top  of
       opareport  (and its analysis capabilities), and accepts the same syntax for input topology
       and snapshot files.

       In addition to being able to run assorted opareport link analysis  reports,  and  generate
       human-readable  output,  this tool additionally analyzes the results and appends a concise
       summary of issues found to the FF_RESULT_DIR/punchlist.csv file.

       -t portsfile

                 Specifies the file with list of local HFI ports used  to  access  fabric(s)  for
                 analysis. Default is /etc/opa/ports.

       -p ports

                 Specifies the list of local HFI ports used to access fabrics for analysis.

                 Default  is  first active port. The first HFI in the system is 1. The first port
                 on an HFI is 1. Uses the format hfi:port,
                 for example:

                 0:0       First active port in system.

                 0:y       Port y within system.

                 x:0       First active port on HFI x.

                 x:y       HFI x, port y.

       -T topology_input

                 Specifies the name of a topology input file to use.  Any   %P  markers  in  this
                 filename  are replaced with the hfi:port being operated on (such as 0:0 or 1:2).
                 Default is /etc/opa/topology.%P.xml. If NONE is  specified,  does  not  use  any
                 topology_input  files.  See  opareport  for  more  information on topology_input

       -X snapshot_input

                 Performs analysis using data in  snapshot_input.  snapshot_input must have  been
                 generated  via  a  previous  opareport  -o  snapshot run. If an errors report is
                 specified, snapshot must have been generated with the opareport -s option.  When
                 this  option  is used, only one port may be specified to select a topology_input
                 file  (unless  -T  specified).  When  this  option  is  used,  clearerrors   and
                 clearhwerrors reports are not permitted.

       -x snapshot_suffix

                 Creates   a   snapshot  file  per  selected  port.  The  files  are  created  in
                 FF_RESULT_DIR with names of the form: snapshotSUFFIX. HFI:PORT.xml.

       -c file

                 Specifies  the   error   thresholds   configuration   file.   The   default   is


                 Supports the following reports:

                 errors    Specifies link error analysis.

                 slowlinks Specifies links running slower than expected.

                           Specifies links configured to run slower than supported.

                           Specifies links connected with mismatched speed potential.

                 all       Includes  all  reports  above. (errors, slowlinks, misconfiglinks, and

                 clear     Includes clearerrors and clearhwerrors.
