14 ibtracert uses SMPs to trace the path from a source GID/LID to a
15 destination GID/LID. Each hop along the path is displayed until the destination
16 is reached or a hop does not respond. By using the -m option, multicast path
17 tracing can be performed between source and destination nodes.
23 \fB\-n\fR, \fB\-\-no_info\fR
24 simple format; don't show additional information
27 show the multicast trace of the specified mlid
29 \fB\-\-node\-name\-map\fR <node-name-map>
30 Specify a node name map. The node name map file maps GUIDs to more user friendly
33 for node name map file format.
37 Most OpenIB diagnostics take the following common flags. The exact list of
38 supported flags per utility can be found in the usage message and can be shown
39 using the util_name -h syntax.
43 \-d raise the IB debugging level.
44 May be used several times (-ddd or -d -d -d).
46 \-h show the usage message
48 \-v increase the application verbosity level.
49 May be used several times (-vv or -v -v -v)
51 \-V show the version info.
55 \-D use directed path address arguments. The path
56 is a comma separated list of out ports.
59 "0,1,2,1,4" # out via port 1, then 2, ...
61 \-G use GUID address argument. In most cases, it is the Port GUID.
65 \-s <smlid> use 'smlid' as the target lid for SM/SA queries.
69 \-C <ca_name> use the specified ca_name.
71 \-P <ca_port> use the specified ca_port.
73 \-t <timeout_ms> override the default timeout for the solicited mads.
75 Multiple CA/Multiple Port Support
77 When no IB device or port is specified, the port to use is selected
78 by the following criteria:
80 1. the first port that is ACTIVE.
82 2. if not found, the first port that is UP (physical link up).
84 If a port and/or CA name is specified, the user request is
85 attempted to be fulfilled, and will fail if it is not possible.
