Chapter 3:
Configuring the Card
Introduction
Configuring the DAG card for data capture involves the following steps:
•
Loading the images and programming the FPGA,
•
Setting the link,
•
Checking the link,
•
Configuring the connections,
•
Capturing data.
The
dagconfig
tool which is also supplied with the DAG 4.5 card allows you
to configure the card to your specific network requirements as well as view
interface statistics.
Sample
dagconfig
outputs are shown later in this chapter.
Line Types
Overview
It is important that you understand the physical characteristics of the network
to which you want to connect before you begin configuring the card.
There are various Ethernet line speeds and corresponding protocols which are
identified using the IEEE naming convention. Each line speed has a set of
requirements associated with it relating to the type of cable, maximum
allowable distance, etc.
Note: If you are unsure about which of the options listed below apply
to your network, please contact your Network Administrator for further
information.
Supported Line Types
The line characteristics supported by the DAG 4.5 card are described below.
Type Description
10Base-T 10 Mbps over two pairs of twisted telephone cable.
100Base-TX 100 Mbps over two pairs of shielded or unshielded
twisted Cat 5 copper cable.
1000Base-T 1000Mbps over four pairs of balanced Cat5 or Cat6
copper cable.
1000Base-LX 1000Mbps over single mode or multi mode fiber optic
cable with long wavelength laser driver (1310nm)
1000Base-SX 1000Mbps over single mode or multi mode fiber optic
cable with short wavelength laser driver (850nm)
Note: For more detailed information regarding Ethernet line types and
speeds, please refer to IEEE Standard 802.3 available from the IEEE
website at
