Checking ethernet link statistics using transponder and burst in mac.js
===============================================================================


1. Requirements
---------------

  mac.js is JavaScript files that require this NVIDIA MODS diagnostic tool to 
  run.


2. Test Setup
-------------

  This test requires two hosts with NVIDIA nForce integrated chipsets. It
supports only the NVIDIA ethernet port or the integrated NvEthernet port on any
NForceX systems. One such ethernet port on one of the hosts is connected to one
such ethernet port on the other host using a cross cable.

  One host acts as the system under test running BurstTest (an external
loopback test), and the other host acts as a transponder echoing the incoming
packets. Upon completion of the test, transmission and reception statistics
are available on each of the hosts.


3. Test Sequence
----------------

- Start transponder software on transponder host.

- Run BurstTest on system under test. Statistics will be written to MODS.LOG
  on the system under test.

- Quit transponder on transponder host by pressing a key. Statistics will be
  written to MODS.LOG on the transponder host.


4. Running the Transponder
--------------------------

  Run 'mods mac.js -trnspndr [args]' at the command line. One or more of the
following command line arguments can be substituted for [args]:

-mii                MII phy.                                
-rgmii              RGMII phy (default).                    
-10mbps             Force link speed to 10Mbps.              
-100mbps            Force link speed to 100Mbps.             
-1000mbps           Force link speed to 1000Mbps.           
-jumboframe         9000 bytes frame is used.                
-verbose            Display detailed information.            
-slave              Use the Mac on Slave Chip(only good for 2P).

Examples:
  
  mods mac.js -trnspndr -mii -100mbps -verbose
  Run the transponder on the NVIDIA MAC with MII phy. 
  Display detailed statistics.
  
  mods mac.js -trnspndr -rgmii -1000mbps -jumboframe 
  Run the transponder with RGMII 1000Mbps and jumbo frame. 
  Display detailed statistics.
  

5. Running the BurstTest
------------------------

  Run 'mods mac.js -burst count [args]' at the command line. One or more of the
following command line arguments can be substituted for [args]:

-mii                MII phy.                                
-rgmii              RGMII phy (default).                    
-10mbps             Force link speed to 10Mbps.              
-100mbps            Force link speed to 100Mbps.             
-1000mbps           Force link speed to 1000Mbps.           
-jumboframe         9000 bytes frame is used.                
-verbose            Display detailed information.            
-slave              Use the Mac on Slave Chip(only good for 2P).
-?                  Print Help Message

Examples:
  
  mods mac.js -burst 2 -rgmii -1000mbps -jumboframe -verbose
  Run the burst test on the NVIDIA MAC with RGMII phy. Speed of 1000mbps is 
  enforced.
  Display detailed statistics.

  
  mods mac.js -burst 1 -mii -10mbps
  Run the burst test on the NVIDIA mac with MII phy at 10Mbps
            
  
6. Data Analysis
----------------

  The statistics log on the system under test shows the transmission statistics
for transmitted packets as well as the reception statistics for packets
returned by the transponder.
  
  The statistics log on the transponder shows the reception statistics for
the packets received from the system under test as well as the transmission
statistics for the packets transmitted by the transponder.

  For a UNIDIRECTIONAL CABLE LENGTH TEST, one would examine the statistics for
the link from the system under test to the transponder. This includes the
transmission statistics of the system under test and the reception statistics
of the transponder.


7. Troubleshooting
------------------

Q: I keep getting link errors even though both the system under test and the
   transponder host are known to be good.
   
A: Make sure that the link parameters match on both systems. One of the 
   linkspeed -10mbps, -100mpbs -1000bps has to be specified . If the speed 
   doesn't match from both host, the error might show.
