NAME

       IBCCCONFIG - configure congestion control settings

SYNOPSIS

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

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>  SwitchPort-
	      CongestionSetting  (SP) <lid|guid> <portnum> <valid> <control_type> <threshold> <packet_size> <cong_parm_marking_rate> CACongestion-
	      Setting (CS) <lid|guid> <port_control> <control_map>  <ccti_timer>  <ccti_increase>  <trigger_threshold>	<ccti_min>  CongestionCon-
	      trolTable (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
