DUMP_MFTS.SH(8)		      OpenIB Diagnostics	       DUMP_MFTS.SH(8)

NAME
       DUMP_MFTS.SH - dump InfiniBand multicast forwarding tables

SYNOPSIS
       dump_mfts.sh  [-h]  [-D]	 [-C  ca_name]	[-P ca_port] [-t(imeout) time‐
       out_ms] [>/path/to/file]

DESCRIPTION
       dump_mfts.sh is a script which dumps the InfiniBand multicast  forward‐
       ing tables (MFTs) in the switch nodes in the subnet.

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	speci‐
       fied  (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.
