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:

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.
