IBTRACERT(8) Open IB Diagnostics IBTRACERT(8)NAME
IBTRACERT -
trace InfiniBand path
SYNOPSIS
ibtracert [options] [<lid|guid> [<startlid> [<endlid>]]]
DESCRIPTION
ibtracert 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
Addressing Flags
-G, --Guid The address specified is a Port GUID
-L, --Lid The address specified is a LID
-s, --sm_port <smlid> use 'smlid' as the target lid for SA queries.
Port Selection flags
-C, --Ca <ca_name> use the specified ca_name.
-P, --Port <ca_port> use the specified ca_port.
Local port Selection
Multiple port/Multiple CA support: when no IB device or port is speci‐
fied (see the "local umad parameters" below), the libibumad library
selects the port to use 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 libibumad library
attempts to fulfill the user request, and will fail if it is not
possible.
For example:
ibaddr # use the first port (criteria #1 above)
ibaddr -C mthca1 # pick the best port from "mthca1" only.
ibaddr -P 2 # use the second (active/up) port from the first available IB device.
ibaddr -C mthca0 -P 2 # use the specified port only.
Debugging flags
-d raise the IB debugging level. May be used several times (-ddd
or -d -d -d).
-e show send and receive errors (timeouts and others)
-h, --help show the usage message
-v, --verbose
increase the application verbosity level. May be used several
times (-vv or -v -v -v)
-V, --version show the version info.
Configuration flags
-t, --timeout <timeout_ms> override the default timeout for the
solicited mads.
--node-name-map <node-name-map> Specify a node name map.
This file maps GUIDs to more user friendly names. See FILES sec‐
tion.
-y, --m_key <key>
use the specified M_key for requests. If non-numeric value (like
'x') is specified then a value will be prompted for.
--config, -z <config_file> Specify alternate config file.
Default: /etc/infiniband-diags/ibdiag.conf
FILES
CONFIG FILE
/etc/infiniband-diags/ibdiag.conf
A global config file is provided to set some of the common options for
all tools. See supplied config file for details.
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.
This functionality is provided by the opensm-libs package. See
opensm(8) for the file location for your installation.
Generically:
# comment
