9.4.6 ibqueryerrors
The default behavior is to report the port error counters which exceed a threshold for each port in
the fabric. The default threshold is zero (0). Error fields can also be suppressed entirely.
In addition to reporting errors on every port, ibqueryerrors can report the port transmit and
receive data as well as report full link information to the remote port if available.

Table 33 - ibqueryerrors Flags and Options
Flags Description
XmitWait The amount of time it takes for the port to be selected. PortSelect had data to
transmit, but no data was sent during the entire wait time because of insuffi-
cient credits or lack of arbitration.
Usually, it identifies slow receivers or traffic oversubscription on particular
links. The counter is only indicative (not an error)
-s <err1,err2,...> Suppresses the errors listed in the comma separated list provided.
For example: To suppress XmitWait counter in the output, run ibqueryer-
rors -s PortXmitWait
-c Suppresses some of the common "side effect" counters. These counters usually
do not indicate an error condition and can be usually be safely ignored.
Note: Currently only PortSwitchRcvRelayErrors counter can be suppressed.
-G <port_guid> -S
<port_guid> --port-guid
Report results for the port specified. For switches results are printed for all
ports not just switch port 0.
-S same as "-G" Provided only for backward compatibility
-D <direct_route> Reports results for the port specified. For switches results are printed for all
ports not just switch port 0.
-r Reports the port information. This includes LID, port, external port (if applica-
ble), link speed setting, remote GUID, remote port, remote external port (if
applicable), and remote node description information.
--data Includes the optional transmit and receive data counters.
--skip-sl Uses the default sl for queries. This is not recommended when using a QoS
aware routing engine as it can cause a credit deadlock.
--threshold-file Specifies an alternate threshold file.
The default is:
