IBFINDNODESUSING(8)        Open IB Diagnostics        IBFINDNODESUSING(8)

NAME top

       ibfindnodesusing - find a list of end nodes which are routed
       through the specified switch and port

SYNOPSIS top

       ibfindnodesusing.pl [options] <switch_guid|switch_name> <port>

DESCRIPTION top

       ibfindnodesusing.pl uses ibroute and detects the current nodes
       which are routed through both directions of the link specified.
       The link is specified by one switch port end; the script finds the
       remote end automatically.

OPTIONS top

       -h     show help

       -R     Recalculate the ibnetdiscover information, ie do not use
              the cached information.  This option is slower but should
              be used if the diag tools have not been used for some time
              or if there are other reasons to believe that the fabric
              has changed.

       -C <ca_name>    use the specified ca_name.

       -P <ca_port>    use the specified ca_port.

   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.
