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.

CONFIG FILE¶
/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.
