SYNOPSIS
========

ibtracert [options] [<lid|guid> [<startlid> [<endlid>]]]


DESCRIPTION
===========

ibtracert uses SMPs to trace the path from a source GID/LID to a
destination GID/LID. Each hop along the path is displayed until
the destination is reached or a hop does not respond. By using
the -m option, multicast path tracing can be performed between source
and destination nodes.

OPTIONS
=======

**-n, --no_info**
        simple format; don't show additional information

**-m**
        show the multicast trace of the specified mlid

**-f, --force**
        force route to destination port
