## NAME



           IBCCQUERY - query congestion control settings/info
    


## SYNOPSIS



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


## DESCRIPTION



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


## OPTIONS



           **Current supported operations and their parameters:**
                  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.
    
       **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:
              /ssd11/FOSS/rdma-core/build/etc/infiniband-diags/ibdiag.conf
    


## FILES

## EXAMPLES



              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
