       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, --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

          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
       -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.
