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>

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
