NAME         top

       ibdiscover.pl - annotate and compare InfiniBand topology

SYNOPSIS         top

       ibdiscover.pl

DESCRIPTION         top

       ibdiscover.pl uses a topology file create by ibnetdiscover and a
       discover.map file which the network administrator creates which
       indicates the nodes to be expected and a ibdiscover.topo file
       which is the expected connectivity and produces a new connectivity
       file (discover.topo.new) and outputs the changes to stdout. The
       network administrator can choose to replace the "old" topo file
       with the new one or certain changes in.

       The syntax of the ibdiscover.map file is:

       <nodeGUID>|port|"Text for node"|<NodeDescription from
       ibnetdiscover format>

       e.g.

       8f10400410015|8|"ISR 6000"|# SW-6IB4 Voltaire port 0 lid 5

       8f10403960558|2|"HCA 1"|# MT23108 InfiniHost Mellanox Technologies

       The syntax of the old and new topo files (ibdiscover.topo and
       ibdiscover.topo.new) are:

       <LocalPort>|<LocalNodeGUID>|<RemotePort>|<RemoteNodeGUID>

       e.g.

       10|5442ba00003080|1|8f10400410015

       These topo files are produced by the ibdiscover.pl tool.
