smpdump - dump InfiniBand subnet management attributes


smpdump [options] <dlid|dr_path> <attribute> [attribute_modifier]


smpdump is a general purpose SMP utility which gets SM attributes from a specified SMA. The result is dumped in hex by default.


LID or DR path to SMA
IBA attribute ID for SM attribute
IBA modifier for SM attribute
Print strings in packet if possible

Addressing Flags

-D, --Direct The address specified is a directed route


[options] -D [options] "0" # self port
[options] -D [options] "0,1,2,1,4" # out via port 1, then 2, ...
(Note the second number in the path specified must match the port being
used. This can be specified using the port selection flag '-P' or the
port found through the automatic selection process.)

-L, --Lid The address specified is a LID

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 specified (see the "local umad parameters" below), the libibumad library selects the port to use by the following criteria:

the first port that is ACTIVE.
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

raise the IB debugging level. May be used several times (-ddd or -d -d -d).

show send and receive errors (timeouts and others)

-h, --help show the usage message

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.

--config, -z <config_file> Specify alternate config file.

Default: /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.


Direct Routed Examples

smpdump -D 0,1,2,3,5 16 # NODE DESC smpdump -D 0,1,2 0x15 2 # PORT INFO, port 2

LID Routed Examples

smpdump 3 0x15 2 # PORT INFO, lid 3 port 2 smpdump 0xa0 0x11 # NODE INFO, lid 0xa0
