SYNOPSIS

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

DESCRIPTION

12       ibccquery  support  the  querying  of  settings  and  other information
13       related to congestion control.
14

OPTIONS

16       Current supported operations and their parameters:
17              CongestionInfo (CI) <addr> CongestionKeyInfo (CK) <addr> Conges‐
18              tionLog  (CL) <addr> SwitchCongestionSetting (SS) <addr> Switch‐
19              PortCongestionSetting (SP) <addr>  [<portnum>]  CACongestionSet‐
20              ting  (CS)  <addr>  CongestionControlTable (CT) <addr> Timestamp
21              (TI) <addr>
22
23       --cckey, -c <cckey> Specify a congestion control (CC) key.  If none  is
24       specified, a key of 0 is used.
25
26   Debugging flags
27       -d     raise  the  IB debugging level.  May be used several times (-ddd
28              or -d -d -d).
29
30       -e     show send and receive errors (timeouts and others)
31
32       -h, --help      show the usage message
33
34       -v, --verbose
35              increase the application verbosity level.  May be  used  several
36              times (-vv or -v -v -v)
37
38       -V, --version     show the version info.
39
40   Addressing Flags
41       -G, --Guid     The address specified is a Port GUID
42
43       -L, --Lid   The address specified is a LID
44
45       -s, --sm_port <smlid>     use 'smlid' as the target lid for SA queries.
46
47   Port Selection flags
48       -C, --Ca <ca_name>    use the specified ca_name.
49
50       -P, --Port <ca_port>    use the specified ca_port.
51
52   Local port Selection
53       Multiple  port/Multiple CA support: when no IB device or port is speci‐
54       fied (see the "local umad parameters"  below),  the  libibumad  library
55       selects the port to use by the following criteria:
56
57          1. the first port that is ACTIVE.
58
59          2. if not found, the first port that is UP (physical link up).
60
61          If  a  port  and/or  CA  name  is  specified,  the libibumad library
62          attempts to fulfill the user request, and will fail  if  it  is  not
63          possible.
64
65          For example:
66
67              ibaddr                 # use the first port (criteria #1 above)
68              ibaddr -C mthca1       # pick the best port from "mthca1" only.
69              ibaddr -P 2            # use the second (active/up) port from the first available IB device.
70              ibaddr -C mthca0 -P 2  # use the specified port only.
71
72   Configuration flags
73       -y, --m_key <key>
74              use the specified M_key for requests. If non-numeric value (like
75              'x') is specified then a value will be prompted for.
76
77       --config, -z  <config_file> Specify alternate config file.
78          Default: /etc/infiniband-diags/ibdiag.conf
