ibnetdiscover and ibchecknet
ibnetdiscover is used to scan the topology of the subnet and converts the output into a
human readable form. Global IDs, node types, port numbers, port Local IDs and
NodeDescriptions are displayed. The full topology is displayed including all nodes and
links with the option of highlighting those which are currently connected. The output may
be printed to a topology file.
Syntax:
ibnetdiscover [options] [<topology-filename>]
Non standard flags:
-1
-H

List of connected nodes
List of connected HCAs
List of connected switches
ibchecknet uses a topology file which has been created by ibnetdiscover to scan the
network validating the connectivity and reporting errors detected by the port counters. The
command runs as follows.
