.. ibccconfig [common_options] [-c cckey] [--dgid gid] <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. NDENT 0.0

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> ... NINDENT --cckey, -c, <cckey> Specify a congestion control (CC) key. If none is specified, a key of 0 is used. --dgid <dgid> destination GID: use when GRH is required in packets (IPv6 format)

Define the common option -d
. NDENT 0.0

-d raise the IB debugging level. May be used several times (-ddd or -d -d -d). NINDENT Define the common option -e
. NDENT 0.0

-e show send and receive errors (timeouts and others) NINDENT Define the common option -h
. -h, --help show the usage message Define the common option -v
. NDENT 0.0

-v, --verbose increase the application verbosity level. May be used several times (-vv or -v -v -v) NINDENT Define the common option -V
. -V, --version show the version info.

Define the common option -G
. -G, --Guid The address specified is a Port GUID Define the common option -L
. -L, --Lid The address specified is a LID Define the common option -s
. -s, --sm_port <smlid> use \(aqsmlid\(aq as the target lid for SA queries. Define the common option -C
. -C, --Ca <ca_name> use the specified ca_name. Define the common option -P
. -P, --Port <ca_port> use the specified ca_port. Explanation of 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: NDENT 0.0 NDENT 3.5 NDENT 0.0 the first port that is ACTIVE. if not found, the first port that is UP (physical link up). NINDENT 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: NDENT 0.0 NDENT 3.5

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.

NINDENT NINDENT NINDENT NINDENT Define the common option -y
. NDENT 0.0

-y, --m_key <key> use the specified M_key for requests. If non-numeric value (like \(aqx\(aq) is specified then a value will be prompted for. NINDENT Define the common option -z
. --config, -z <config_file> Specify alternate config file. NDENT 0.0 NDENT 3.5 Default: /etc/infiniband-diags/ibdiag.conf NINDENT NINDENT
