Introduction

Overview

The Endace DAG 3.8S card provides the means to transfer data at the full speed of the

network into the memory of the host computer, with zero packet loss, in even worst-case

conditions. Further, unlike a Network Interface Card (NIC), Endace products actively

manage the movement of network data into memory while only consuming a minimal

amount of the host computer's resources. The full attention of the CPU remains focused on

the analysis of incoming data without a constant stream of interruptions as new packets

arrive from the network. For a busy network link, this feature has a turbo-charging effect

similar to that of adding a second CPU to the system.

The DAG 3.8S is a two port, PCIx card that allows capture and transmission of data. It

supports packet and cell capture and transmit applications for OC3c or OC12c, ATM or

Packet-over-SONET (PoS) networks. The DAG 3.8S has two transceivers which can be

operated simultaneously allowing a single card to monitor one or both directions of a full-

duplex link. An optional Co-Processor daughter card can be added for enhanced filtering.

Card Features

The following features are available on this DAG card. Note: Different firmware images

may be required. Not all features are available on each firmware image. For further

information on which feature is available in what firmware image, see Firmware images

(page ).

•OC3 / STM-1 and OC12c / STM-4c

•ATM

•TERF

•Co-Processor based IPF (If Co-Processor fitted.)

•Co-Processor based AAL5 (If Co-Processor fitted.)

System Requirements

General

The minimum system requirements for the DAG 3.8S card are:

•A computer, with at least a Intel Xeon 1.8GHz or faster and a minimum of 1GB RAM.

•At least one free PCI-X slot supporting 66MHz operation..

•Software distribution requires 60MB free space.

•For details of the supported operating systems, see one of the following documents:

•EDM04-01 DAG Software Installation Guide

•Current release notes - See the Documentation CD or the Endace support website

at https://www.endace.com/support

Operating System

This document assumes you are installing the DAG 3.8S card in a computer which already

has an operating system installed. To install refer to EDM04-01 DAG Software Installation

Guide. All related documentation is included on the CD shipped with the DAG 3.8S card.

Other Systems

For advice on using an operating system that is substantially different from any of those

specified above, please contact Endace Customer Support at [email protected].

EDM01-09v15 DAG_3.8S_Card_User_Guide

Card Description

The DAG 3.8S card standard configuration supports receive-only packet and cell capture

applications for OC3c or OC12c, ATM or Packet-over-SONET (PoS) networks.

The DAG 3.8S card has two transceivers which can be operated simultaneously allowing a

single card to monitor one or both directions of a full-duplex link.

The DAG 3.8S card is also capable of transmitting packets at 100% line rate on both ports

while simultaneously receiving packets at 100% line rate on both ports.

Older versions of the DAG 3.8S card use standard fixed optical transceivers while newer

versions (Rev G onwards) have pluggable optical transceivers.

Both versions are shown next.

Battery removal – don’t do it!

Removing the battery from a DAG card voids your warranty.

Removing the battery from a DAG card will cause the loss of encryption key used to decode

the DAG card's firmware. Once the encryption key is lost the DAG card must be returned to

Endace for reprogramming.

The battery in this product is expected to last a minimum of 10 years.

Caution

Risk of explosion if the battery is replaced by an incorrect type.

Dispose of used batteries carefully.

Card Architecture

Serial SONET/SDH optical data is received by two optical interfaces, and passed through de-

multiplexers. The network data feeds immediately into two physical layer FPGAs.

The SONET/SDH payload data is then sent to the main FPGA. This FPGA contains the

DUCK timestamp engine, packet record processor, and PCI-X interface logic.

Because of component close association, packets or cells are time-stamped accurately. Time

stamped packet records are stored in an external FIFO before transmission to the host.

The diagram below shows the DAG 3.8S card's major components and flow of data:

EDM01-09v15 DAG_3.8S_Card_User_Guide

Line Types

It is important that you understand the physical characteristics of the network to which you

want to connect. If your configuration settings do not match your network, the DAG 3.8S

card will not function as expected.

Note: If you are unsure about which of the options listed below to apply to your network,

please contact your Network Administrator for further information.

Supported Line Types

The line characteristics supported by the DAG 3.8S card are described below.

Type Description

PoS/ATM Packet over SONET/Asynchronous Transfer Mode.

OC-3/OC-3c

A SONET network line with transmission speeds up to 155.52 Mbit/s using

fiber optics. Also called STM-1 (SDH).

OC-12/OC-12c A SONET network line with transmission speeds up to 622.08 Mbit/s using

fiber optics. Also called STM-4 (SDH).

EDM01-09v15 DAG_3.8S_Card_User_Guide

Extended Functions

Co-Processor

The DAG 3.8S card is equipped with a Co-Processor connector which can be used with the

optional Endace DAG Co-Processor as a data processing tool.

The specifications for the Co-Processor IP filtering/packet classification are:

•Packets are classified by TCP/IP header fields and/or payload content.

•Up to 16,384 TCP/IP header classification rules.

•Classification rules are assigned a user-defined 16-bit identifier

•Packets matching classification rules are assigned the matching rule's identifier.

•Programmable actions may be associated with each rule identifier. For example, The

packet should either be dropped, or presented to the host.

•Packets presented to the host include the rule-match identifier in the record header.

The specifications for the coprocessor ATM AAL5 Reassembler are:

•Supports up to 65,536 simultaneously active VCI/VPI's

•Supports simultaneous reassembly of up to 65,536 AAL5 frames

•Selected VPI/VCI discovery, state management, and ageing

•Supports up to full OC-12/STM-4 cell rate on both interfaces simultaneously [~2.8

Mcells/sec]

•Rich statistics, counters, and timeouts.

Inline Forwarding

for more information on

DAG coprocessor purchasing and pricing details.

The DAG 3.8S card supports inline forwarding which enables the card to receive and

transmit packets directly from a single memory. This allows you to forward packets from the

DAG card receive interface(s) to the DAG cards transmit interface(s) without the requirement

to copy them. Using inline forwarding you can receive, inspect, filter and forward packets

between ports.

dagfwddemo which is a tool supplied with your DAG card demonstrates how you can apply a

user-defined BSD Packet Filter (BPF) to the traffic forwarded by the DAG card. Packets

which match the filter are forwarded, while packets that do not match are dropped.

For more detailed information on inline forwarding and using dagfwddemo please refer to the

EDM04-04 dagfwddemo User Guide available from the support section of the Endace website

at http://www.endace.com
