IBMgtSim – Infiniband Management Simulator

Synopsys

IBMgtSim [-h] [-V mod-verb-pair-list] [-l log-file] [-p server-port]
  [-w num-threads] [-f flow-tcl-file] [-s seed] -t topology

Description

Simulates the Fabric as defined by the given topology file and start a server to handle MAD requests from clients like OpenSM.

Arguments

-t topology

A topology file describing the fabric to be simulated (see ibdm-topo-file)

Options

-s seed

The seed to be used for random number generation.

-f flow-tcl-file

A tcl file to be sourced after the fabric is setup.

-l log-file

Set the log file of the simulator (default is /var/cache/ibutils/ibsim.log)

-p server-port

Set the port number the server attaches to (default 46517)

-w num-threads

The number of threads processing the mads

-V <module-verbosity-pair-list>

Provides a fine grain control over the log file verbosity. Given list of pairs of simulator software module names and their verbosity levels – every module is separatly controlled. The first value (missing module name) is controlling the default verbosity for all un-explicitly set modules.

Current Verbosity Levels:

 MsgShowFatal = 0x01;

 MsgShowError = 0x02;

 MsgShowWarning= 0x04;

 MsgShowInfo = 0x08;

 MsgShowVerbose= 0x10;

 MsgShowContext= 0x20;

 MsgShowSource = 0x40;

 MsgShowTime = 0x80;

 MsgShowModule = 0x100;

 MsgShowMads = 0x200;

 MsgShowFrames = 0x400;

 MsgShowAll = 0xffff;

 MsgDefault = 0x62f;

Software Modules:

client, server, dispatcher, node, sma, lftMad, mftMad, vlArbMad, pKeyMad, portInfoMad

Examples -V flag values might be:

 -V 0xffff = Full verbosity on all modules

 -V ‘0x3 server 0x6f2 sma 0xffff’ = Only fatal and error for all modules

 full verbosity for the SMA module and default verbosity for the

 Server module.
