## NAME



           ibroute - query InfiniBand switch forwarding tables
    


## SYNOPSIS



           ibroute [options] [<dest dr_path|lid|guid> [<startlid>
           [<endlid>]]]
    


## DESCRIPTION



           ibroute uses SMPs to display the forwarding tables (unicast
           (LinearForwardingTable or LFT) or multicast
           (MulticastForwardingTable or MFT)) for the specified switch LID
           and the optional lid (mlid) range.  The default range is all valid
           entries in the range 1...FDBTop.
    


## OPTIONS



           **-a, --all**
                  show all lids in range, even invalid entries
    
           **-n, --no_dests**
                  do not try to resolve destinations
    
           **-M, --Multicast**
                  show multicast forwarding tables In this case, the range
                  parameters are specifying the mlid range.
    
       **Addressing Flags**
           **-D, --Direct** The address specified is a directed route
    
              Examples:
                 [options] -D [options] "0"          # self port
                 [options] -D [options] "0,1,2,1,4"  # out via port 1, then 2, ...
    
                 (Note the second number in the path specified must match the port being
                 used.  This can be specified using the port selection flag '-P' or the
                 port found through the automatic selection process.)
    
           **-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.
    
           **-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.
    
           **--node-name-map <node-name-map> **Specify a node name map.
              This file maps GUIDs to more user friendly names.  See FILES
              section.
    
           **--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.

              ibroute -G 0x08f1040023 # resolve switch by GUID
