NAME

       DUMP_LFTS.SH - dump InfiniBand unicast forwarding tables

SYNOPSIS

       dump_lfts.sh [-h] [-D] [-C ca_name] [-P ca_port] [-t(imeout) timeout_ms] [>/path/to/dump-file]

DESCRIPTION

       dump_lfts.sh  is a script which dumps the InfiniBand unciast forwarding tables (MFTs) in the switch nodes
       in the subnet.

       The dump file format is compatible with loading into OpenSM  using  the  -R  file  -U  /path/to/dump-file
       syntax.

OPTIONS

       -D dump forwarding tables using direct routed rather than LID routed SMPs

       -h show help

   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.

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

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

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

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.
