EDM01-33v1 DAG_7.5G4_Card_User_Guide

Introduction

Overview

The Endace DAG 7.5G4 card provides the means to transfer data at the full speed from 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 interrupts 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 7.5G4 card provides independent four port Ethernet network monitoring at Gigabit speeds and supports header only or variable length capture. It is capable of transmitting and receiving on each channel simultaneously allowing a single card to operate inline, monitoring and transmitting in both directions on a full duplex link.

The DAG 7.5G4 card is a four port, PCIe card that allows capture and transmission of data. It a multi-speed card, capable of speeds of 10/100/1000 Mbps. The speed of both ends must match. The card auto negotiates the correct speed.

Half Duplex is not supported by this DAG card.

EDM01-33v1 DAG_7.5G4_Card_User_Guide

Card Description

The DAG 7.5G4 card provides four optical or copper Gigabit Ethernet interfaces. It is capable of full line rate (1,000Mbps) capture and transmission of Ethernet traffic. Full packet capture at line rate allows recording of all header information and/or payload with a high precision timestamp.

The key features of the card are:

• Four SFP ports for 1000Base-SX or 1000Base-LX optical Ethernet or 10/100/1000Base-

T copper Ethernet,

• Header only or variable length capture,

• Full line rate transmit,

• 100% capture into host memory at full line rate for IP packets from 48 to 9600 bytes

• Conditioned clock with PPS input and local synchronization capability.

• PCIe x4 Gen 1.0a, 8 Gigabits per second (Raw). Actual performance of PCIe will

depend on the motherboard and other factors in the system architecture.

• Bit level masks applied to the first 64 bytes of each packet can be used to classify

packets and make drop/capture decisions.

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.

EDM01-33v1 DAG_7.5G4_Card_User_Guide

Card Architecture

Serial Ethernet network data received by each 1000Base interface flows directly into the Field

Programmable Gate Array (FPGA).

The FPGA contains the packet processor, PCIe interface logic and the DAG Universal Clock

Kit (DUCK) timestamp engine. The DUCK provides high resolution per-packet timestamps

which can be accurately synchronized.

Note: For further information on the DUCK and time synchronization, see

Synchronizing

Clock Time 41 (page ) later in this user guide.

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

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

The diagram below shows the DAG 7.5G4G4 card's major components and flow of data.

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 7.5G4 card will not function as expected.

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 to apply to your network,

please contact your Network Administrator for further information.

Supported Line Types

The line characteristics supported by the DAG 7.5G4 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

http://www.ieee.org.

EDM01-33v1 DAG_7.5G4_Card_User_Guide

Extended Functions

Data Stream Management

The DAG 7.5G4 card supports the Data Stream Manager (DSM) feature. DSM allows you to

drop packets or route them to a particular receive stream based on the packet contents,

physical port and the output of two load balancing algorithms.

The DSM logic is implemented in firmware on the DAG 7.5G4 card and does not require

intervention from the host CPU once it is configured.

Note: For detailed information on using the Data Stream Manager please refer to EDM04-

10 Data Stream Management API Programming Guide and EDM04-07 dsm-loader User Guide available from the support section of the Endace website at

http://www.endace.com

Filter / Load Balancing Block

Packets are received from the line and stamped with an ERF header, then passed to the filter

and load balancing block. The filter block applies eight bit-mask filters simultaneously from

the start of the packet, producing a single true/false value for each filter (64 bytes).

The load balancing block applies two algorithms to the packet data, also producing one

true/false Boolean output per algorithm.

Lookup Table Block

The lookup table accepts the filter and load balancing outputs. It also receives the physical

port the packet arrived on and calculates a classification (also known as color) for the packet.

Colorizer and Drop Block

The color is then passed to the Colorizer And Drop (CAD) block to check if the packet should

be dropped. If not the color is inserted into the packet ERF record header and the packet

record is passed to the packet steering module.

Packet Steering Module

The Packet steering module looks at the color information contained in the record and

determines which receive stream the record should be routed to.

Inline Forwarding

The DAG 7.5G4 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

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

http://www.endace.com.

dagfwddemo please refer to the

EDM01-33v1 DAG_7.5G4_Card_User_Guide

Timed Release TERF (TR-TERF)

The Timed Release TERF (TR-TERF) module is a option that enables you to transmit an ERF stream while reproducing the timestamps of the packets within that stream. It is able to transmit on all channels.

TR-TERF has two modes of operation. They are:

• No Delay Mode, and

• Relative Timed Release Mode.

EDM01-33v1 DAG_7.5G4_Card_User_Guide

Installation

Introduction

The DAG 7.5G4 card operates on an 4 lane PCIe bus and can be installed in any free 4 lane PCIe slot.

The PCIe bus allows multiple DAG cards to be installed without affecting the bandwidth used by each DAG 7.5G4 card.

DAG Software package

The latest DAG Software package must be installed before you install the DAG 7.5G4 card itself. See EDM04-01 DAG Software Installation Guide, which is included on the CD shipped with the DAG 7.5G4 card.

Inserting the DAG Card

Caution:

It is very important to protect both the computer and the DAG 7.5G4 card from damage by electro-static discharge (ESD). Failure to do so could cause damage to components and subsequently cause the card to partially or completely fail.

1. Turn power to the computer OFF.

2. Remove the PCIe bus slot screw and cover.

3. Using an approved ESD protection device attach the end with the strap to your wrist

and pull or clip firmly so there is firm contact with your wrist.

4. Securely attach the clip on the other end of the strap to a solid metal area on the

computer chassis as shown below.

5. Insert the DAG 7.5G4 card into PCIe bus slot ensuring it is firmly seated.

6. If this DAG card requires an external power supply, complete the following steps: a. Connect the supplied (or equivalent) power cable to the external power connector

on the DAG card.

b. Connect the cable to the appropriate power connector on your server's power

supply unit.

7. Check the free end of the card fits securely into the card-end bracket that supports the

weight of the card.

8. Secure the card with the bus slot cover screw.

9. Turn power to the computer ON.

10. Ensure the blue (FPGA successfully programmed) LED on the DAG card illuminates.

EDM01-33v1 DAG_7.5G4_Card_User_Guide

Port connector

The DAG 7.5G4 card has 4 x Small Form Factor (SFP) socket connectors. Each connector consists of an optical fiber or copper transmitter and receiver.

Note: The DAG 7.5G4 supports both optical and copper transceivers.

The DAG 7.5G4G4 has an 8-pin RJ45 socket located below the optical port connectors on the card bracket. This socket is available for connection to an external time synchronization source.

Caution:

Never connect anything other than a PPS input to the time synchronization sockets.

EDM01-33v1 DAG_7.5G4_Card_User_Guide

Pluggable Optical Transceivers

Overview

The DAG 7.5G4 card supports industry standard Small Form-factor Pluggable (SFP) optical transceivers.

The transceivers consist of two parts:

• Mechanical chassis attached to the circuit board

• Transceiver unit which may be inserted into the chassis

Note: You must select the correct transceiver type to match the optical parameters of the

network to which you want to connect. Configuring the card with the wrong transceiver type may damage the card.

You can connect the transceiver to the network via LC-style optical connectors.

For further information on pluggable optical transceivers please refer to the Endace website

http://www.endace.com

Optical modules

The optical power range depends on the particular SFP module that is fitted to the DAG

4.5Z2/4.5Z8 card. Optics modules are supplied in either Single or Multi mode. See the following table for details.

Optical power is measured in dBm. This is decibels relative to 1 mW where 10 dB is equivalent to a factor of 10 in power. A negative optical power value indicates power that is less than 1 mW. The most sensitive devices can work at power levels down as low as -30dBm or 1µW.

The DAG 4.5Z2/4.5Z8 card optics power module specification is shown below:

If you are in doubt over the light levels available for the DAG card receive ports, check the light levels using an optical power meter.

Cover DAG 4.5Z2/4.5Z8 card transmit ports with LC-style plugs to prevent dust and mechanical hazards damaging optics if not in use.

EDM01-33v1 DAG_7.5G4_Card_User_Guide

Power Input

Note: The optical power input to the DAG card must be within the receiver’s dynamic

range. See the previous table for details. If it is slightly outside of this range it will cause an increased bit error rate. If it is significantly outside of this range the system will not be able to lock onto the signal.

When power is above the upper limit the optical receiver saturates and fails to function. When power is below the lower limit the bit error rate increases until the device is unable to obtain lock and fails. In extreme cases, excess power can damage the receiver.

When you set up the DAG card you should measure the optical power at the receiver and ensure that it is within the specified power range. If it is not, adjust the input power as follows:

• Insert an optical attenuator if power is too high, or

• Change the splitter ratio if power is too high or too low.

Splitter Losses

Splitters have the insertion losses either marked on their packaging or described in their accompanying documentation. General guidelines are:

• A 50:50 splitter will have an insertion loss of between 3 dB and 4 dB on each output

• 90:10 splitter will have losses of about 10 dB in the high loss output, and <2 dB in the

low loss output

Note: Endace recommends that you do not use a combination of single mode and multi

mode fibers and optics modules on the same link, as the quality of the received signal cannot be guaranteed.

If you have no choice but to mix single mode and multi mode you should be aware

that a single mode input connected to a multi mode fiber will have some attenuation but may still be acceptable. However a multi mode input connected to a single mode fiber will likely have large and unpredictable losses.

Pluggable Copper Transceivers

The DAG 7.5G4 card supports industry standard Small Form-factor pluggable (SFP) copper transceivers.

The transceivers consist of two parts:

• Mechanical chassis attached to the circuit board

• Transceiver unit which may be inserted into the chassis

Endace recommends that you use Cat6 copper cable. The DAG 4.5Z2/4.5Z8 card copper module specification is shown below:

Configuring the DAG card

Introduction

Configuring the DAG 7.5G4 card ready for capturing data requires the following steps:

• Setting up the FPGA

•

Preparing the DAG card for use 19 (page )

Configuring the DAG Card 20 (page )

•

Viewing the DAG card statistics 29 (page )

Once the DAG 7.5G4 is configured you can start capturing data, see

capture data 31 (page ) for details on capturing data.

Before configuring the DAG card

Before configuring the FPGA, you should ensure that:

•

dagmem has been run and memory allocated to each installed DAG card.

•

Refer to the Installing the drivers section for the required Operating system in EDM04-01 DAG Software Installation Guide for the further details.

dagload has been run so that all DAG drivers have been installed.

EDM01-33v1 DAG_7.5G4_Card_User_Guide

Setting up the FPGA

All DAG cards have at least one Field-Programmable Gate Array (FPGA). The FPGA contains the firmware for the installed DAG card. The firmware defines how the DAG card operates when capturing data and contains the specific configuration.

For the FPGA on the DAG 7.5G4 there are up to four firmware images stored in the ROM:

• The factory image - contains fixed basic functionality for operating the DAG card. It

cannot be overwritten by the user.

• The user images 1 to 3 - User image #1 is programmed at the factory. Other images

may or may not be pre-programmed. User images can be updated by the user either to update to a new release, or to load an image with different functionality than that originally shipped from the factory.

By default, the DAG 7.5G4 card boots user image #1, unless the Force factory jumper is fitted. For more details on the Force factory jumper, see Booting from the factory image is normally only required if the DAG card cannot boot from any of the user images because of a ROM programming error when updating the user images.

Selecting the firmware image to boot

Use the following command to select the firmware image from which to boot. on the DAG

7.5G4 the are up to four images from which to select.

dagconfig -d0 -p x
