# ibtracert

## 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
    
           **-f, --force**
                  force route to destination port
    
       **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.
    
           **--ports-file <ports-file>   **Specify a ports file.
              This file contains multiple source and destination lid or guid
              pairs. See FILES section.
    
       **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:
              /ssd11/FOSS/rdma-core/build/etc/infiniband-diags/ibdiag.conf
    


## FILES



       **CONFIG FILE**
           /ssd11/FOSS/rdma-core/build/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.

       **PORTS FILE FORMAT**
           The ports file can be used to specify multiple source and
           destination pairs.  They can be lids or guids.  If guids, use the
           -G option to indicate that.
