Reference Guide for the Model GA620 Gigabit Ethernet Card
5-2 Troubleshooting
• The optional -l parameter defines a file in which to log the test results.
A text copy of the DDTP test results are placed in the specified file.
For example, to test the second card in a system and store the test results in log.txt in the
current directory, you could enter the following command:
>dos4gw e:\diag\ddtp -c 1 -l log.txt
• The optional -e parameter activates the external loopback test. Both the internal and
external loopback example tests show 1000 packets sucessfully received with 0 errors
detected, indicating that the card is functioning properly.
The test result from the previous example could look like this:

The internal loopback test is executed automatically.
Note:
The external loopback test requires a loopback cable connecting the RX port to the
TX port on the network card. If a loopback cable is not used, the external loopback test
fails
