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: /etc/infiniband−diags/ibdiag.conf

FILES

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.

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
