.SH SYNOPSIS
.sp
smpdump [options] <dlid|dr_path> <attribute> [attribute_modifier]
.SH DESCRIPTION
.sp
smpdump is a general purpose SMP utility which gets SM attributes from a
specified SMA. The result is dumped in hex by default.
.SH OPTIONS
.INDENT 0.0
.TP
.B \fBdlid|drpath\fP
LID or DR path to SMA
.TP
.B \fBattribute\fP
IBA attribute ID for SM attribute
.TP
.B \fBattribute_modifier\fP
IBA modifier for SM attribute
.TP
.B \fB\-s, \-\-string\fP
Print strings in packet if possible

.SS Addressing Flags
.\" Define the common option -D for Directed routes
.
.sp
\fB\-D, \-\-Direct\fP     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 \(aq\-P\(aq or the
   port found through the automatic selection process.)

\fB\-P, \-\-Port <ca_port>\fP    use the specified ca_port.
.\" Explanation of local port selection
.
.SS Local port Selection
.sp
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:
.INDENT 0.0
.INDENT 3.5
.INDENT 0.0
.IP 1. 3
the first port that is ACTIVE.
.IP 2. 3
if not found, the first port that is UP (physical link up).
.UNINDENT
.sp
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.
.sp
For example:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
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.
