NAME

       IBDM Topology File

       The topology file describes the IB connectivity and systems included in the network.  It
       serves two purposes:

       1. Support for arbitrary system names to be later used in every report that IBDM
       generates.
       2. Connectivity verification: The specified network topology is verified against the
       discovered one. Mismatch errors resulting from missing cables and/or wrong connections are
       reported by IBADM.

       The topology file is composed "system" sections. Each such section describes the
       connectivity of one system to other systems in the network. The first line of each section
       is a declaration of the system composed of a system-type, its system-name section, and
       optional configuration details. The lines to follow until the next empty line describe the
       connections between this system ports to the other systems. The following is a formal
       definition of a system section syntax.

       An example is listed afterwards.

       SYSTEM-TYPE SYSTEM-NAME [CFG: <b1>=<modifier>, [<b2>=<modifier>]...]

               LOCAL-PORT-PANEL-NAME -> REM-SYS-TYPE REM-SYS-NAME REM-PORT-PANEL-NAME

               LOCAL-PORT-PANEL-NAME -> REM-SYS-TYPE REM-SYS-NAME REM-PORT-PANEL-NAME

               LOCAL-PORT-PANEL-NAME -> REM-SYS-TYPE REM-SYS-NAME REM-PORT-PANEL-NAME

               . . .

       SYSTEM-TYPE SYSTEM-NAME [CFG: <b1>=<modifier>, [<b2>=<modifier>]...]

               LOCAL-PORT-PANEL-NAME -> REM-SYS-TYPE REM-SYS-NAME REM-PORT-PANEL-NAME

               LOCAL-PORT-PANEL-NAME -> REM-SYS-TYPE REM-SYS-NAME REM-PORT-PANEL-NAME

               . . .

       . . .

       Where:

       SYSTEM-TYPE and REM-SYS-TYPE
           Any system that has a corresponding IBNL definition. See man ibdm-ibnl-file

       SYSTEM-NAME
           The name of the system described in this topology file section.

       LOCAL-PORT-PANEL-NAME
           The name of the local system port. The numbers printed on the front panel are used
           together with Ln for Leaf no. N or Sn for Spine no. N.

       REM-SYS-NAME
           The name of the system connected to the local port.

       REM-PORT-PANEL-NAME
           A name of the remote system port. We use the numbers as printed on the front panel and
           Ln for Leaf number N or Sn for Spine number N.

EXAMPLE

       The following is a topology file for a simple cluster with one 24 port switch and two
       HCAs. The first HCA named H-1 and connect to the fabric with its two ports. The second HCA
       named H-2. The switch is of type MTS2400 and is named S-1

       MTS2400 S-1
          P1 -> MT23108 H-1 P1
          P2 -> MT23108 H-1 P2
          P24 -> MT23108 H-2 P1

OPTIONAL CFG SECTION

       This section in the system declaration line describes the special customization of each
       board of the system.

       That is the CFG string is a set of comma-separated sub-fields. Each sub-field describes
       some special configuration of a corresponding system board. The actual semantics of the
       specific board modifiers is defined by the IBNL of the specific system.

EXAMPLE

       The following is an example of a definition-line in a topology file of the MTS9600 switch
       system. This switch system can have up to eight leafs and four spines. This example of the
       MTS9600 lacks (R) leafs no.6,7 and 8, and lacks spines no. 3 and 4.

       MTS9600 PartialGz1 CFG: leaf3=R,leaf5=R,leaf7=R,spine1=R
