Chapter 5: Running Data Capture Software
Introduction
For a typical measurement session, the
scripts/dag42start
script is
edited and used to operate the cards directly.
In this chapter This chapter covers the following sections of information.
Starting Capture Session
High Load Performance
Timestamps
5.1 Starting Capture Session
Description
The various tools used for data capture are in the
tools
sub-directory.
For a typical measurement session, ensure the driver is loaded, the
firmware has been downloaded, and the card is configured.
The integrity of the card’s physical layer is then set and checked.
Process
Setting a data capture session is described in the following process.
Process Description
Load Xilink receive
image.
For a typical measurement session, first move to
the
dag
directory.
Load the driver.
Load the Xilinx receive image to each DAG.
For example, with two DAG 4.2S cards
installed:
drv/dagload
tools/dagrom -rvp –d dag0 -f xilinx/dag423pos-erf.bit
tools/dagrom -rvp –d dag1 -f xilinx/dag423pos-erf.bit
Although the images are named pos, they can be
configured to capture ATM traffic.
Check integrity. Set, and then check the integrity of the physical
layer to both DAGs.
