14.3.9 ibnetdiscover
ibnetdiscover performs IB subnet discovery and outputs a readable topology file. GUIDs, node
types, and port numbers are displayed as well as port LIDs and NodeDescriptions. All nodes
(and links) are displayed (full topology). Optionally, this utility can be used to list the current
connected nodes by node-type. The output is printed to standard output unless a topology file is
specified.
