.SH SYNOPSIS

.sp

ibhosts [options] [<topology\-file>]

.SH DESCRIPTION

.sp

ibhosts is a script which either walks the IB subnet topology or uses an

already saved topology file and extracts the CA nodes.

.SH OPTIONS

.\" Define the common option -C

.

.sp

\fB\-C, \-\-Ca <ca_name>\fP    use the specified ca_name.

.\" Define the common option -P

.

.sp

\fB\-P, \-\-Port <ca_port>\fP    use the specified ca_port.

.\" Define the common option -t

.

.sp

\fB\-t, \-\-timeout <timeout_ms>\fP override the default timeout for the solicited mads.

.\" Define the common option -y

.

.INDENT 0.0

.TP

.B \fB\-y, \-\-m_key <key>\fP

use the specified M_key for requests. If non\-numeric value (like \(aqx\(aq)

is specified then a value will be prompted for.

.UNINDENT

.\" Define the common option -h

.

.sp

\fB\-h, \-\-help\fP      show the usage message

.\" Define the common option -z

.\" 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.

.SS CONFIG FILE

.sp

@IBDIAG_CONFIG_PATH@/ibdiag.conf

.sp

A global config file is provided to set some of the common options for all

tools.  See supplied config file for details.

.\" Common text to describe the node name map file.

.

.SS NODE NAME MAP FILE FORMAT

.sp

The node name map is used to specify user friendly names for nodes in the

output.  GUIDs are used to perform the lookup.

.sp

This functionality is provided by the opensm\-libs package.  See \fBopensm(8)\fP

for the file location for your installation.
