.SH SYNOPSIS
.sp
sminfo [options] sm_lid | sm_dr_path [modifier]
.SH DESCRIPTION
.sp
Optionally set and display the output of a sminfo query in human readable
format. The target SM is the one listed in the local port info, or the SM
specified by the optional SM lid or by the SM direct routed path.
.sp
Note: using sminfo for any purposes other then simple query may be very
dangerous, and may result in a malfunction of the target SM.

.\" 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.
