NAME

       IBROUTERS - show InfiniBand router nodes in topology

SYNOPSIS

       ibrouters [options] [<topology-file>]

DESCRIPTION

       ibrouters  is  a script which either walks the IB subnet topology or uses an already saved
       topology file and extracts the router 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.

       -y, --m_key <key>
              use the specified M_key for requests. If non-numeric value (like 'x') is  specified
              then a value will be prompted for.

       -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.
