NAME
       IBSWITCHES - show InfiniBand switch nodes in topology

SYNOPSIS
       ibswitches [options] [<topology-file>]

DESCRIPTION
       ibswitches  is  a  script  which either walks the IB subnet topology or
       uses an already saved topology file and extracts the switch nodes.

OPTIONS
       -C, --Ca <ca_name>    use the specified ca_name.

       -P, --Port <ca_port>    use the specified ca_port.

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

       -h, --help      show the usage message

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

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

   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.

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.

       Generically:
