       IBCCCONFIG - configure congestion control settings


       ibccconfig [common_options] [-c cckey] <op> <lid|guid> [port]


       ibccconfig supports the configuration of congestion control settings on
       switches and HCAs.

       WARNING -- You should understand what you are doing before  using  this
       tool.  Misuse of this tool could result in a broken fabric.


       Current supported operations and their parameters:
              CongestionKeyInfo   (CK)  <lid|guid>  <cckey>  <cckeyprotectbit>
              <cckeyleaseperiod>   <cckeyviolations>   SwitchCongestionSetting
              (SS)    <lid|guid>    <controlmap>   <victimmask>   <creditmask>
              <threshold>    <packetsize>    <csthreshold>     <csreturndelay>
              <markingrate>    SwitchPortCongestionSetting   (SP)   <lid|guid>
              <portnum>  <valid>  <control_type>   <threshold>   <packet_size>
              <cong_parm_marking_rate>   CACongestionSetting  (CS)  <lid|guid>
              <port_control>   <control_map>   <ccti_timer>    <ccti_increase>
              <trigger_threshold>   <ccti_min>   CongestionControlTable   (CT)
              <lid|guid> <cctilimit> <index> <cctentry> <cctentry> ...

       --cckey, -c, <cckey> Specify a congestion control (CC) key.  If none is
       specified, a key of 0 is used.

   Debugging flags
       -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)

       -h, --help      show the usage message

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

       -V, --version     show the version info.

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

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

       -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

          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
       -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.

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

       A global config file is provided to set some of the common options  for
       all tools.  See supplied config file for details.
