NAME

       IBNODES - show InfiniBand nodes in topology

SYNOPSIS

       ibnodes [options] [<topology-file>]

DESCRIPTION

       ibnodes  is a script which either walks the IB subnet topology or uses an already saved topology file and
       extracts the IB nodes (CAs and switches).

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  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.

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.
