IBTRACERT(8) OpenIB Diagnostics IBTRACERT(8)NAME
ibtracert- trace InfiniBand path
SYNOPSISibtracert [-d(ebug)] [-v(erbose)] [-G(uids)] [-n(o_info)] [-m mlid] [-s
smlid] [-C ca_name] [-P ca_port] [-t(imeout) timeout_ms] [-V(ersion)]
[--node-name--map <node-name-map>] [-h(elp)] [<lid|guid> [<startlid>
[<endlid>]]]
DESCRIPTIONibtracert uses SMPs to trace the path from a source GID/LID to a desti‐
nation GID/LID. Each hop along the path is displayed until the destina‐
tion is reached or a hop does not respond. By using the -m option, mul‐
ticast path tracing can be performed between source and destination
nodes.
OPTIONS-n, --no_info
simple format; don't show additional information
-m show the multicast trace of the specified mlid
--node-name-map <node-name-map>
Specify a node name map. The node name map file maps GUIDs to
more user friendly names. See ibnetdiscover(8) for node name
map file format.
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
-d raise the IB debugging level.
May be used several times (-ddd or -d -d -d).
-h show the usage message
-v increase the application verbosity level.
May be used several times (-vv or -v -v -v)
-V show the version info.
# Addressing flags
-G use GUID address argument. In most cases, it is the Port GUID.
Example:
"0x08f1040023"
-s <smlid> use 'smlid' as the target lid for SM/SA queries.
# Other common flags:
-C <ca_name> use the specified ca_name.
-P <ca_port> use the specified ca_port.
-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:
1. the first port that is ACTIVE.
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.
EXAMPLES
Unicast examples
ibtracert 4 16 # show path between lids 4 and 16
ibtracert-n 4 16 # same, but using simple output format
ibtracert-G 0x8f1040396522d 0x002c9000100d051 # use guid addresses
Multicast example
ibtracert-m 0xc000 4 16 # show multicast path of mlid 0xc000
between lids 4 and 16
