NAME

       IBPORTSTATE  -  handle  port  (physical)  state  and  link  speed of an
       InfiniBand port

SYNOPSIS

       ibportstate [options] <dest dr_path|lid|guid> <portnum> [<op>]

DESCRIPTION

       ibportstate allows the port state and port physical state of an IB port
       to  be  queried  (in  addition  to link width and speed being validated
       relative to the peer port when the port queried is a switch port), or a
       switch  port to be disabled, enabled, or reset. It also allows the link
       speed/width enabled on any IB port to be adjusted.

OPTIONS

       <op>

              Supported ops: enable, disable,  reset,  speed,  espeed,  fdr10,
              width, query,
                     on,  off,  down,  arm, active, vls, mtu, lid, smlid, lmc,
                     mkey, mkeylease, mkeyprot (Default is query)

              enable, disable, and reset are only allowed on switch ports  (An
              error is indicated if attempted on CA or router ports)

              off change the port state to disable.

              on  change  the port state to enable(only when the current state
              is disable).

              speed and width are allowed on any port

              speed values are the legal values for  PortInfo:LinkSpeedEnabled
              (An  error  is indicated if PortInfo:LinkSpeedSupported does not
              support this setting)

              espeed is allowed on any port supporting extended link speeds

              fdr10 is allowed on any  port  supporting  fdr10  (An  error  is
              indicated  if  port's  capability  mask  indicates extended link
              speeds are not supported  or  if  PortInfo:LinkSpeedExtSupported
              does not support this setting)

              width  values are legal values for PortInfo:LinkWidthEnabled (An
              error  is  indicated  if  PortInfo:LinkWidthSupported  does  not
              support  this  setting)  (NOTE:  Speed and width changes are not
              effected until the port goes through link renegotiation)

              query also validates port characteristics  (link  width,  speed,
              espeed, and fdr10) based on the peer port. This checking is done
              when the port queried is a switch port as it relies on  combined
              routing (an initial LID route with directed routing to the peer)
              which can only be done on a switch. This  peer  port  validation
              feature  of  query  op requires LID routing to be functioning in
              the subnet.

              mkey, mkeylease, and mkeyprot are only allowed on CAs,  routers,
              or switch port 0 (An error is generated if attempted on external
              switch ports).  Hexadecimal and octal mkeys may be specified  by
              prepending  the  key  with  '0x'  or  '0',  respectively.   If a
              non-numeric value (like 'x') is specified  for  the  mkey,  then
              ibportstate will prompt for a value.

   Addressing Flags
       -L, --Lid   The address specified is a LID

       -G, --Guid     The address specified is a Port GUID

       -D, --Direct     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 '-P' or the
             port found through the automatic selection process.)

       -s, --sm_port <smlid>     use 'smlid' as the target lid for SA queries.

   Port Selection flags
       -C, --Ca <ca_name>    use the specified ca_name.

       -P, --Port <ca_port>    use the specified ca_port.

   Local port Selection
       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:

          1. the first port that is ACTIVE.

          2. if not found, the first port that is UP (physical link up).

          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.

          For example:

              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.

   Configuration flags
       --config, -z  <config_file> Specify alternate config file.
          Default: /etc/infiniband-diags/ibdiag.conf

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

       -y, --m_key <key>
              use the specified M_key for requests. If non-numeric value (like
              'x') is specified then a value will be prompted for.

   Debugging flags
       -h, --help      show the usage message

       -d     raise  the  IB debugging level.  May be used several times (-ddd
              or -d -d -d).

       -e     show send and receive errors (timeouts and others)

       -K, --show_keys
              show security keys  (mkey,  smkey,  etc.)  associated  with  the
              request.

       -v, --verbose
              increase  the  application verbosity level.  May be used several
              times (-vv or -v -v -v)

       -V, --version     show the version info.
