IBDIAGNET(1)		     IB DIAGNOSTIC PACKAGE		  IBDIAGNET(1)

NAME
       ibdiagnet - IB diagnostic net

SYNOPSYS
       ibdiagnet [-c <count>] [-v] [-r] [-t <topo-file>] [-s <sys-name>]
	 [-i <dev-index>] [-p <port-num>] [-o <out-dir>] [-lw <1x⎪4x⎪12x>]
	 [-ls <2.5⎪5⎪10>] [-pm] [-pc] [-P <<PM counter>=<Trash Limit>>]

DESCRIPTION
       ibdiagnet scans the fabric using directed route packets and extracts
       all the available information regarding its connectivity and devices.
       It then produces the following files in the output directory (which
       defined by the -o option (see below)).

FILES
       ibdiagnet.log -
	   A dump of all the application reports generate according to the
	   provided flags

       ibdiagnet.lst -
	   List of all the nodes, ports and links in the fabric

       ibdiagnet.fdbs -
	   A dump of the unicast forwarding tables of the fabric switches

       ibdiagnet.mcfdbs -
	   A dump of the multicast forwarding tables of the fabric switches

       ibdiagnet.masks -
	   In case of duplicate port/node Guids, these file include the map
	   between masked Guid and real Guids

       ibdiagnet.sm -
	   List of all the SM (state and priority) in the fabric

       ibdiagnet.pm -
	   A dump of the pm Counters values, of the fabric links

       In addition to generating the files above, the discovery phase also
       checks for duplicate node/port GUIDs in the IB fabric. If such an error
       is detected, it is displayed on the standard output. After the discov‐
       ery phase is completed, directed route packets are sent multiple times
       (according to the -c option) to detect possible problematic paths on
       which packets may be lost. Such paths are explored, and a report of the
       suspected bad links is displayed on the standard output.

       After scanning the fabric, if the -r option is provided, a full report
       of the fabric qualities is displayed.  This report includes:

       * SM report
       * Number of nodes and systems
       * Hop-count information
	   maximal hop-count, an example path, and a hop-count histogram
       * All CA-to-CA paths traced
       * Credit loop report
       * mgid-mlid-HCAs matching table

       Note: In case the IB fabric includes only one CA, then CA-to-CA paths
       are not reported.  Furthermore, if a topology file is provided, ibdiag‐
       net uses the names defined in it for the output reports.

OPTIONS
       -c <count>      :
	   Min number of packets to be sent across each link (default = 10)
       -v	       :
	   Enable verbose mode
       -r	       :
	   Provides a report of the fabric qualities
       -t <topo-file>  :
	   Specifies the topology file name
       -s <sys-name>   :
	   Specifies the local system name. Meaningful only if a topology file
	   is specified
       -i <dev-index>  :
	   Specifies the index of the device of the port used to connect to
	   the IB fabric (in case of multiple devices on the local system)
       -p <port-num>   :
	   Specifies the local device's port num used to connect to the IB
	   fabric
       -o <out-dir>    :
	   Specifies the directory where the output files will be placed
	   (default = /tmp)
       -lw <1x⎪4x⎪12x> :
	   Specifies the expected link width
       -ls <2.5⎪5⎪10>  :
	   Specifies the expected link speed
       -pm	       :
	   Dump all the fabric links, pm Counters into ibdiagnet.pm
       -pc	       :
	   Reset all the fabric links pmCounters
       -P <PM=<Trash>> :
	   If any of the provided pm is greater then its provided value, print
	   it to screen
       -h⎪--help       :
	   Prints the help page information
       -V⎪--version    :
	   Prints the version of the tool
       --vars	       :
	   Prints the tool's environment variables and their values

ERROR CODES
       1 - Failed to fully discover the fabric
       2 - Failed to parse command line options
       3 - Failed to intract with IB fabric
       4 - Failed to use local device or local port
       5 - Failed to use Topology File
       6 - Failed to load requierd Package
