EDM01-36v10 DAG_9.2X2_Card_User_Guide - Introduction

Inline forwarding

The DAG 9.2X2 card supports inline forwarding which enables the card to receive and transmit packets

directly from a single memory buffer. 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

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

Timed Release TERF (TR-TERF)

The Timed Release TERF (TR-TERF) module is an option that enables you to retransmit an ERF packet

trace while reproducing the time intervals of the packets within that stream. It is able to transmit on all

channels.

TR-TERF has two modes of operation.

•

No Delay Mode.

•

Relative Timed Release Mode.

Triggered Timed Release TERF (TR-TERF)

The Triggered Timed Release TERF (TR-TERF) module extends the functionality of TR-TERF by setting an

absolute time at which to start the transmission is to start. This enables synchronization of multiple

replay sessions across multiple DAG cards and even systems, provided that the DAG card clocks are

synchronized.
