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.
