In this section This section covers the following topics of information.
•DAG 3.6EP Card Architecture
•DAG 3.6ET Card Architecture
1.3.1 DAG 3.6EP Card Architecture
Description The DAG 3.6EP has two independent 10/100 Ethernet interfaces.
Each can be connected to a separate switch or hub, and autonegotiate with
the connected equipment.
Ethernet
framers Each single half or full-duplex 10 or 100Mbps Ethernet connection passes
into a port of the DAG card. Two Ethernet framers look at data from each
port independently. The DAG card captures from half duplex or full
duplex links.
Packet time
stamping Serial Ethernet data is received by the interface, and fed through a framer
into the upper of two Xilinx FPGA’s. This FPGA contains an Ethernet
processor and the DUCK timestamp engine.
Because of component close association, packets or cells are time-stamped
accurately. Time stamped packet records are then stored in the lower
FIFO.

Records
transfer Records transfer from FIFO into lower FPGA, which has interfaces to the
PCI bus and then all records are written to host memory.
1.3.2. DAG 3.6ET Card Architecture
Description The DAG 3.6ET is designed for tapping both directions of a single copper
10 or 100Mbps Ethernet link in a completely passive and fail-safe manner.
The DAG card will capture from half duplex or full duplex links. The
DAG card does not interfere in the link negotiation process in any way, so
full duplex links will remain full duplex after being connected through the
DAG card.
Ethernet
framers A single half or full-duplex 10 or 100Mbps Ethernet connection passes
into one port of the DAG card, and out the other un-interrupted.
Two Ethernet framers look at data travelling in each direction on the
connection without interfering with the link. The DAG card cannot
transmit onto this link at all, and even if the DAG 3.6ET is turned off the
network link integrity is assured.
Packet time
stamping Serial Ethernet data is received by the interface, and fed through a framer
into the upper of two Xilinx FPGA’s. This FPGA contains an Ethernet
processor and the DUCK timestamp engine.
Because of component close association, packets are time-stamped
accurately. Time stamped packet records are then stored in a FIFO.
Records
transfer Records transfer from FIFO into lower FPGA, which has interfaces to the
PCI bus and then all records are written to host memory.
Description The DAG 3.6E and associated data capture system minimum operating
requirements are:
•PC, at least Pentium II 400 MHz, Intel 440BX, GX or newer chip set
•256 MB RAM
•At least one free PCI free slot with 3.3V and 5V power
•Software distribution requires free space of 30MB
Operating
system For convenience, a Debian 3.1 [Sarge] Linux system is included on the
Endace Software Install CD. Endace currently supports Windows XP,
Windows Server 2000, Windows Server 2003, FreeBSD, RHEL 3.0, and

3.0 CONFIDENCE TESTING DAG 3.6E CARD
Introduction The confidence testing is a process to determine the DAG 3.6E card series
is functioning relative to the LED functions status. The process also
involves a card capture session, and configuration in the style of what you
can see you can change.
The interface statistics are inspected. This section also has information
regarding reporting of problems.
In this chapter This chapter covers the following sections of information.
•DAG Cards Sensitivity
•Interpreting DAG 3.6E Card LED Status
•DAG Card Capture Session
•Configuration in WYSYCC style
•Inspect Interface Statistics
•Reporting Problems
3.1 DAG Cards Sensitivity
In this section This section covers the following topics of information.
•DAG 3.6 EP Card Sensitivity
•DAG 3.6ET Card Sensitivity
3.1.1 DAG 3.6 EP Card Sensitivity
Description The DAG 3.6EP card is compliant to IEEE 802.3 standards in respect to
maximum cable lengths, and operates as a normal Ethernet device.
Activity lights indicate network traffic in each direction on the link.
3.1.2 DAG 3.6ET Card Sensitivity
Description The insertion loss associated with inserting a DAG 3.6ET card into an
existing link is <1dB. With this low insertion loss, the DAG 3.6ET can be
inserted into long cable runs.
By default the DAG 3.6ET will attempt to automatically detect the line
speed of either 10 or 100Mbps, and light link status lights to indicate that it
has detected the network correctly.
Activity lights indicate network traffic in each direction on the link.
The DAG 3.6ET card cannot introduce traffic onto the network link, and
the link will remain up even if the DAG 3.6ET card is misconfigured or
powered off.

3.3 DAG Card Capture Session
Description The DAG 3.6E uses two ASIC framer devices to support capturing of
Ethernet data frames. The card supports both 10Base-T and 100Base-TX
standards.
The default behaviour is to autodetect the correct link speed, however the
configuration can be forced if necessary.
A successful DAG 3.6E card capture session is accomplished by receiver
ports optical signal levels and checking the card is locked to stream data.
This is followed by configuring DAG for normal use.
Procedure Follow these steps for a successful DAG 3.6E card capture session.
Step 1. Check Cabling
Ensure cabling is correctly connected and that RJ45 connectors are clipped
into the sockets.
Step 2. Check link layer configuration
Learn about the link layer configuration in use at the network link being
monitored. Important parameters include:
•10Base-T vs. 100Base-TX configuration
•Full vs. Half Duplex.
If the information cannot be obtained reliably, the card can be made to work
by varying parameters until data is arriving at the host system.
Step 3. List Current Settings
For DAG 3.6E framer configuration and statistics the dagthree tool is
supplied.
Calling dagthree without arguments lists current settings.
The dagthree -h prints a help listing on tool usage.
dag@endace:~$ dagthree -d dag0

Procedure (continued)
Step 4. Check FPGA Images Loaded
Before starting to configure the card, ensure the most recent pair of FPGA
images have been loaded onto the card.
The link status and activity LEDs will not activate until the upper FPGA
firmware is downloaded.
dag@endace:~$ dagrom -rvp –d dag0 -f xilinx/dag36epci-erf.bit
dag@endace:~$ dagld -x –d dag0 –f xilinx/dag36epp-erf.bit
Step 5. Configure Card for Normal Use
Configure according to local settings using dagthree default command.
NOTE: If dagthree default command is not used the card will operates
correctly but mem display will show 0 memory allocated to the receive
stream buffer until after the first capture.
dag@endace:~$ dagthree default
linkA noreset tap auto enableA
linkB noreset tap auto enableB
packet novarlen slen=48 noalign64
packetA drop=0
packetB drop=0
pci 33MHz 32-bit buf=32MB rxstreams=1 txstreams=0 mem=32:0
Step 6. Check Card Operation

packet varlen slen=48 noalign64
packetA drop=0
packetB drop=0
pci 33MHz 32-bit buf=32MB rxstreams=1 txstreams=0 mem=32:0
NOTE: The card status will include tap for each link line for the DAG
3.6ET, and will contain port for each link line for the DAG 3.6EP. These
values are not software adjustable.
Step 2. Select Configuration Option
Choose from complete list of configuration options supported:
reset Reset Ethernet framers, set auto mode.
default Reset Ethernet framers, set auto mode.
auto Set autonegotiate mode, card detects rate.
10 Force 10BaseT mode,10Mbps.
100 Force 10BaseT mode,100Mbps.
[en|dis]ableA Enable or disable port A direction for capture.
[en|dis]ableB Enable or disable port B direction for capture.
[no]varlen Dis/enable variable length capture. Otherwise record
length padded to slen.
slen= Capture X bytes of packet content.
[no]align64 Generate records with 64-bit alignment [default 32-bit]
Step 3. Force DAG 3.6E to 10Mbps Mode.
While monitoring a Mbps connection and autodetection fails to switch to
10Mbps, use
dagthree 10 to force DAG 3.6E to 10Mbps mode.
