Name

opapmaquery — Performs individual PMA queries against a specific LID. It is very useful in displaying port runtime information.

Syntax

opapmaquery [-v] [-s sl] [-l lid] [-h hfi] [-p port] [-o otype [-m port] [-n mask] [-e mask] [-w mask]]

Options

--help

Produces full help text.

-v

Specifies the verbose output. Can be specified more than once for additional openib debugging and libibumad debugging.

-s sl

Specifies different service level. Default is SM SL.

-l lid

Specifies the destination LID. Default is local port.

-h/--hfi hfi

Specifies the SuperNIC, numbered 1..n. Using 0 specifies that the -p port port is a system-wide port number. Default is 0.

-p/--port port

Specifies the port, numbered 1..n. Using 0 specifies the first active port. Default is 0.

-o otype

Specifies the output type. Default is getportstatus. Refer to for supported options.

Valid output types are:

classportinfo

Specifies the class of port info.

getportstatus

Specifies the list of port counters. Supported options:

[-m port] [-w vl mask]
clearportstatus

Clears the port counters. Supported options:

[-n port mask] [-e counter mask] [-w vl mask]
getdatacounters

Specifies the list of data counters. Supported options:

[-n port mask] [-w vl mask]
geterrorcounters

Specifies the list of error counters. Supported options:

[-n port mask] [-w vl mask]
geterrorinfo

Specifies the list of error info. Supported options:

[-n port mask]
clearerrorinfo

Clears the error info. Supported options:

-h and -p options permit a variety of selections:

-h 0

First active port in the system (Default).

-h 0 -p 0

First active port in the system.

-h x

First active port on SuperNIC x.

-h x -p 0

First active port on SuperNIC x.

-h 0 -p y

Port y within the system (no matter which ports are active).

-h x -p y

SuperNIC x, port y.

otype Options Vary By Report

-m port

Specifies the port in destination device to query/clear. Required when using -l option for all but -o classportinfo.

Performance Management Agent

Local Identifier - This is a 24-bit address local to a subnet that is assigned to end nodes by the subnet manager, providing additional features related to routing algorithms.

Subnet Manager or Subnet Management

Service Level

Forward Explicit Congestion Notification - This is an alert sent to the receiver that congestion is occuring. The receiver can notify the sender to take action to avoid congestion.

Backward Explicit Congestion Notification - This is an alert sent to the sender that congestion has been detected. The sender should implement congestion avoidance procedures.

Fabric Manager - This is an OPX Software component responsible for managing the fabric using management packets over a dedicated virtual lane (VL15).

Virtual Lane - This feature allows multiple, multiplexed, independent data to stream onto a single physical link.
