NAME

smpdump − dump InfiniBand subnet management attributes

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

dlid|drpath

LID or DR path to SMA

attribute

IBA attribute ID for SM attribute

attribute_modifier

IBA modifier for SM attribute

−s, −−string

Print strings in packet if possible

Addressing Flags

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

Examples:
[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:

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.

−−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.

EXAMPLES

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
