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
