       ibccquery support the querying of settings and other information related to congestion control.

          ibccquery CongestionInfo 3              # Congestion Info by lid
          ibccquery SwitchPortCongestionSetting 3 # Query all Switch Port Congestion Settings
          ibccquery SwitchPortCongestionSetting 3 1 # Query Switch Port Congestion Setting for port 1

CONFIGFILE
       /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.

Currentsupportedoperationsandtheirparameters:
              CongestionInfo   (CI)   <addr>   CongestionKeyInfo   (CK)   <addr>   CongestionLog   (CL)   <addr>
              SwitchCongestionSetting  (SS)   <addr>   SwitchPortCongestionSetting   (SP)   <addr>   [<portnum>]
              CACongestionSetting (CS) <addr> CongestionControlTable (CT) <addr> Timestamp (TI) <addr>

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

   Debuggingflags-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.

   AddressingFlags-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.

   PortSelectionflags-C,--Ca<ca_name>    use the specified ca_name.

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

   LocalportSelection
       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.

   Configurationflags-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
