.SH DESCRIPTION
.PP
ibnetdiscover performs IB subnet discovery and outputs a human 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 nodetype. The output is printed to standard output
unless a topology file is specified.
.SH OPTIONS
.PP
.TP
\fB\-l\fR, \fB\-\-list\fR
List of connected nodes
.TP
\fB\-g\fR, \fB\-\-grouping\fR
Show grouping. Grouping correlates IB nodes by different vendor specific
schemes. It may also show the switch external ports correspondence.
.TP
\fB\-H\fR, \fB\-\-Hca_list\fR
List of connected CAs
.TP
\fB\-S\fR, \fB\-\-Switch_list\fR
List of connected switches
.TP
\fB\-R\fR, \fB\-\-Router_list\fR
List of connected routers
.TP
\fB\-s\fR, \fB\-\-show\fR
Show progress information during discovery.
.TP
\fB\-\-node\-name\-map\fR <node-name-map>
Specify a node name map. The node name map file maps GUIDs to more user
friendly names. See file format below.
.TP
\fB\-\-cache\fR <filename>
Cache the ibnetdiscover network data in the specified filename. This
cache may be used by other tools for later analysis.
.TP
\fB\-\-load\-cache\fR <filename>
Load and use the cached ibnetdiscover data stored in the specified
filename. May be useful for outputting and learning about other
fabrics or a previous state of a fabric.
.TP
\fB\-\-diff\fR <filename>
Load cached ibnetdiscover data and do a diff comparison to the current
network or another cache. A special diff output for ibnetdiscover
output will be displayed showing differences between the old and current
fabric. By default, the following are compared for differences: switches,
channel adapters, routers, and port connections.
.TP
\fB\-\-diffcheck\fR <key(s)>
Specify what diff checks should be done in the \fB\-\-diff\fR option above.
Comma separate multiple diff check key(s). The available diff checks
are: \fIsw\fR = switches, \fIca\fR = channel adapters, \fIrouter\fR = routers,
\fIport\fR = port connections, \fIlid\fR = lids, \fInodedesc\fR = node
descriptions. Note that \fIport\fR, \fIlid\fR, and \fInodedesc\fR are
checked only for the node types that are specified (e.g. \fIsw\fR,
\fIca\fR, \fIrouter\fR). If \fIport\fR is specified alongside \fIlid\fR
or \fInodedesc\fR, remote port lids and node descriptions will also be compared.
.TP
\fB\-p\fR, \fB\-\-ports\fR
Obtain a ports report which is a
list of connected ports with relevant information (like LID, portnum,
GUID, width, speed, and NodeDescription).
.TP
\fB\-m\fR, \fB\-\-max_hops\fR
Report max hops discovered.
.SH COMMON OPTIONS
Most OpenIB diagnostics take the following common flags. The exact list of
supported flags per utility can be found in the usage message and can be shown
using the util_name -h syntax.
# Debugging flags
.PP
\-d raise the IB debugging level.
May be used several times (-ddd or -d -d -d).
.PP
\-e show send and receive errors (timeouts and others)
.PP
\-h show the usage message
.PP
\-v increase the application verbosity level.
May be used several times (-vv or -v -v -v)
.PP
\-V show the version info.
# Other common flags:
.PP
\-C <ca_name> use the specified ca_name.
.PP
\-P <ca_port> use the specified ca_port.
.PP
\-t <timeout_ms> override the default timeout for the solicited mads.
Multiple CA/Multiple Port Support
When no IB device or port is specified, the port to use is selected
by the following criteria:
.PP
1. the first port that is ACTIVE.
.PP
2. if not found, the first port that is UP (physical link up).
If a port and/or CA name is specified, the user request is
attempted to be fulfilled, and will fail if it is not possible.
.SH TOPOLOGY FILE FORMAT
The topology file format is human readable and largely intuitive.
Most identifiers are given textual names like vendor ID (vendid), device ID
(device ID), GUIDs of various types (sysimgguid, caguid, switchguid, etc.).
PortGUIDs are shown in parentheses (). For switches, this is shown on the
switchguid line. For CA and router ports, it is shown on the connectivity
lines. The IB node is identified followed by the number of ports and a quoted
the node GUID. On the right of this line is a comment (#) followed by the
NodeDescription in quotes. If the node is a switch, this line also contains
whether switch port 0 is base or enhanced, and the LID and LMC of port 0.
Subsequent lines pertaining to this node show the connectivity. On the
left is the port number of the current node. On the right is the peer node
(node at other end of link). It is identified in quotes with nodetype
followed by - followed by NodeGUID with the port number in square brackets.
Further on the right is a comment (#). What follows the comment is
dependent on the node type. If it it a switch node, it is followed by
the NodeDescription in quotes and the LID of the peer node. If it is a
CA or router node, it is followed by the local LID and LMC and then
followed by the NodeDescription in quotes and the LID of the peer node.
The active link width and speed are then appended to the end of this
output line.
An example of this is:

When grouping is used, IB nodes are organized into chasses which are
numbered. Nodes which cannot be determined to be in a chassis are
displayed as "Non-Chassis Nodes". External ports are also shown on the
connectivity lines.
.SH NODE NAME MAP FILE FORMAT
The node name map is used to specify user friendly names for nodes in the
output. GUIDs are used to perform the lookup.
