IBTRACERT(8) Open IB Diagnostics IBTRACERT(8)

IBTRACERT -

ibtracert [options] [<lid|guid> [<startlid> [<endlid>]]]

ibtracert uses SMPs to trace the path from a source GID/LID to a destination GID/LID. Each hop along the path is displayed until the destination is reached or a hop does not respond. By using the -m option, multicast path tracing can be performed between source and destination nodes.

-n, --no_info
simple format; don't show additional information
-m
show the multicast trace of the specified mlid
-f, --force
force route to destination port

-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.

-C, --Ca <ca_name> use the specified ca_name.

-P, --Port <ca_port> use the specified ca_port.

Multiple port/Multiple CA support: when no IB device or port is specified (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.




-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.

-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 section.


-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


/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.

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
<guid> "<name>"
