# ib_fabric_check [clear|scan|fullscan] [<output_dir>] [<link_speed>] [<link_width>]
• clear – The clear option is used to reset the port counters.
• fullscan – The fullscan option adds checking the link receive, link down, and port
receive port counter errors.
• link_speed and link_width – The link_speed and link_width options allow you
to indicate the expected link speed and width, respectively. If a port is found not to have either
of these expected values it is indicated as such in either scan mode (scan or fullscan).
Files – The ib_fabric_check utility will create the following log files in the output_dir, if
specified. The default location is a subdirectory in the current directory named yymmdd_hhmmss_ib.
