NAME

       IBTRACERT -

trace InfiniBand path

   SYNOPSIS
       ibtracert [options] [<lid|guid> [<startlid> [<endlid>]]]

   DESCRIPTION
       ibtracert uses SMPs to trace the path from a source GID/LID to a destination GID/LID. Each
       hop along the path is displayed until the  destination  is  reached  or  a  hop  does  not
       respond.  By  using  the -m option, multicast path tracing can be performed between source
       and destination nodes.

   OPTIONS
       -n, --no_info

              simple format; don't show additional information

       -m

              show the multicast trace of the specified mlid

   Addressing Flags
       -G, --Guid     The address specified is a Port GUID

       -L, --Lid   The address specified is a LID

       -s, --sm_port <smlid>     use 'smlid' as the target lid for SA queries.

   Port Selection flags
       -C, --Ca <ca_name>    use the specified ca_name.

       -P, --Port <ca_port>    use the specified ca_port.

   Local port Selection
       Multiple port/Multiple CA support: when no IB device or port is specified (see the  "local
       umad  parameters"  below),  the libibumad library selects the port to use 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 libibumad library attempts  to  fulfill  the
          user request, and will fail if it is not possible.

          For example:

          ibaddr                 # use the first port (criteria #1 above)
          ibaddr -C mthca1       # pick the best port from "mthca1" only.
          ibaddr -P 2            # use the second (active/up) port from the first available IB device.
          ibaddr -C mthca0 -P 2  # use the specified port only.

   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, --help      show the usage message

       -v, --verbose

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

       -V, --version     show the version info.

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

       --node-name-map <node-name-map> Specify a node name map.

          This file maps GUIDs to more user friendly names.  See FILES section.

       -y, --m_key <key>

              use the specified M_key for requests. If non-numeric value (like 'x') is  specified
              then a value will be prompted for.

       --config, -z  <config_file> Specify alternate config file.

          Default: /etc/infiniband-diags/ibdiag.conf

   FILES
   CONFIG FILE
       /etc/infiniband-diags/ibdiag.conf

       A  global  config  file  is provided to set some of the common options for all tools.  See
       supplied config file for details.

   NODE NAME MAP FILE FORMAT
       The node name map is used to specify user friendly names for nodes in the  output.   GUIDs
       are used to perform the lookup.

       This  functionality  is  provided  by the opensm-libs package.  See opensm(8) for the file
       location for your installation.
