DESCRIPTION

       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.

OPTIONS

       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 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

EXAMPLES

          ibccconfig SwitchCongestionSetting 2 0x1F 0x1FFFFFFFFF 0x0 0xF 8 0 0:0 1  # Configure Switch Congestion Settings
          ibccconfig CACongestionSetting 1 0 0x3 150 1 0 0                          # Configure CA Congestion Settings to SL 0 and SL 1
          ibccconfig CACongestionSetting 1 0 0x4 200 1 0 0                          # Configure CA Congestion Settings to SL 2
          ibccconfig CongestionControlTable 1 63 0 0:0 0:1 ...                      # Configure first block of Congestion Control Table
          ibccconfig CongestionControlTable 1 127 0 0:64 0:65 ...                   # Configure second block of Congestion Control Table
