Introduction
This chapter provides an overview of the Packet Replicator’s features and capabilities.
ongratulations on the purchase of your new EtherSeries PR-6606. This is a simple, easily configured
C
packet replicating device containing three Ethernet interfaces.
The PR-6606 replicates UDP packets through any IP network. The PR-6606 has three Ethernet LAN ports
and a serial port. The Ethernet ports are 10/100/1000 BaseT, copper, MDI/MDIX auto-sensing. The serial
port is used for initial setup to configure the IP address.
The PR-6606 duplicates some or all of the UDP packets passing through it. The original packet is passed
unchanged; if selected for duplication, it is duplicated and the duplicates sent to configured addresses.
All UDP packets are candidates for duplication, selected based upon configured criteria. The selection of a
packet to be duplicated may be based upon any combination of the source IP address, the destination
address, and UDP port number. Additional flexibility is provided with the selection criteria which may
include multiple address ranges for the source, destination as well as UDP port selected.
Each packet selected by one of the five selection rules may be duplicated to as many as ten recipient IP
addresses. UDP port numbers may be passed intact with no change to the destination port number, or to a
different UDP port number substituted for the original one.
The PR-6606 is bidirectional. Packets being returned through the PR-6606 may be passed unchanged, or
duplicated according to duplication rules.
As all UDP packets are candidates for selection, the PR-6606 may be used to duplicate SNMP, NTP,
SCADA protocols including DNP/UDP, and MODBUS/UDP, as well as all other UDP packets.
The PR-6606 is managed via web browser.
PR-6606 Applications
The PR-6606 is in used SCADA, SNMP, netflow, streaming video, streaming audio, and other applications
where it is useful to have a single device send duplicate data streams to multiple devices. In short, may be
applied any time a single UDP packet needs to be duplicated.
Since the packets from the PR-6606 appear to be sent from the originating device, any responses to those
packets will be returned to the originating device. This back-path is without any action by the PR-6606.
In installations where multicast packets are required and only a unicast path is available, the PR-6606 can
translate multicast UDP addressing to unicast UDP addresses in a bidirectional operation.

Features
Other Protocols
The PR-6606 operates only on UDP/IP packets. All other protocols are passed through the device
unchanged.
DHCP Protocol
The PR-6606 may be configured as a DHCP client.
Extensive Packet Selection Rules
User defined selection criteria is configured in "rules". Each rule allows packets to be selected based upon
source IP address, destination IP address, and destination IP port number. IP address and port entries may be
a single value such as one IP address (192.168.2.2 for example) or one port number (for example 3001) or a
range such as 192.168.1.2 to 192.168.1.230 or port 5001 through 8000. If no port number is entered, all
UDP packets meeting other selection criteria are duplicated. To insure the PR-6606 will replicate the
desired packets, the PR-6606 must be inserted in the network path between the original packet's source and
original packet's destination. Furthermore, to prevent MAC table corruption in any layer-2 switches, the
destination of a replicated packet must also reside on a different LAN port from the original source. To
summarize, the original source cannot be located on the same PR-6606 LAN port as the original destination
or replicated destination.
Upgradeable Firmware
Firmware upgrades may be installed using any web browser.
Security Features
The web interface used to configure the PR-6606 may be secured using HTTPS SSL. The secure web
server operates using the SSL protocol which allows for the use of x509 certificates to identify and
authenticate web servers and web browsers. You may generate a pair of x509 certificates within the
PR-6606 or import certificates from your external certificate authority.
On-board Tools
The PR-6606 contains diagnostic tools such as extensive logging, statistics, traceroute, ping, and a simple
packet sniffer to aid in network troubleshooting.
Installation Location
To insure the PR-6606 will replicate the desired packets, the PR-6606 must be inserted in the network path
between the original packet's source and original packet's destination. Furthermore, to prevent MAC table
corruption in any layer-2 switches, the destination of a replicated packet must also reside on a different
LAN port from the original source. To summarize, the original source cannot be located on the same
PR-6606 LAN port as the original destination or replicated destination.

Software Requirements
The PR-6606 replicated only UDP/IP packets. It also bridges any valid Ethernet protocol between it's
Ethernet ports, similarly to a switch. The initial IP address may be entered using any terminal or
terminal emulation software on a PC, or the default may be used if appropriate for your network.
Any standard web browser may be used for configuration once the PR-6606 is configured with a valid IP
address.

PR-6606 Hardware
Introduction
The PR-6606 three Ethernet ports and two USB ports. There is also a RS-232 serial port used for initial IP
address configuration (if needed).
Configuration
This model contains a serial interface to be used in initial setup (if needed). IF the default IP address is not
appropriate for your LAN, connect a terminal to the serial port following the instructions in the
configuration section. The setup port is always active. Follow the command line setup instructions to
configure a compatible IP address. Once a compatible IP address is available, the browser setup screens are
used to complete the unit's configuration.

Rear Panel LED Indicators
One set of indicators For Each Ethernet Port
The green LED to the left of each Ethernet port is a LAN activity indicator. This LED flashes with
activity on the Ethernet (even if the activity isn't directly to this unit).
The yellow/green LED to the right of each Ethernet port is the Ethernet Status indicator. It is lit amber
when the port is connected to a 1000BaseT switch, green for 100BaseT. It is not lit for 10BaseT
connections.
Rear Panel USB Connectors
There are two USB connectors. They are interchangeable, and only the first one that senses a USB device
connection is activated. These are only used for transferring certificate files.
Rear Panel RS-232 Connector
The DE-9 (PC 9-pin) connector is used for command line setup. A cross-over cable is required to use this
with any standard PC serial port. Terminal configuration is 9600 bps, 8N1 .

Installation
This Chapter details the installation process for the PR-6606.
Overview
The PR-6606 is configured using a web browser directed to its address. If the default address of
192.168.0.1 is appropriate for your local network, then plug it in and simply direct your web browser to the
PR-6606 (using https if you've configured it to use https, otherwise use http:) without using a proxy and
continue with configuration. If this address is not appropriate for your network, the IP address must be
configured using the initial terminal method below.
Help Screens and Field Edits
The field names on all configuration screens are hyperlinks to context sensitive help screens. Simply click
on the field name to bring up a second window with the help information. Close that window to return to
your entry screen.
Entries are always tested for valid values. However, there are many “valid” values that are not appropriate
for any given configuration. So, “appropriateness” isn’t tested. For example, an IP address of
300.400.500.256 will not be accepted, but the field will accept an IP address that is not appropriate for
your installation.
Installation and Configuration
1. Configure the IP address
If the default address (192.168.0.1) is appropriate for your network, skip to step 2, “Connect the
Ethernet Cable”.
1. Connect a terminal or PC running terminal emulation program (Hyperterm, Procomm, etc) to the serial
port.
2. Start the terminal emulation program using 9600 bps, 8-bits, No parity, No flow control.

2. Connect the Ethernet Cable
Connect a LAN cable from your hub or switch to a LAN port. Reboot with a power cycle. The PR-6606
will now be available to any web browser on the same LAN segment. If your web browser does not see it,
verify that you do not have a proxy server configured in the browser and are using https instead of http for
a secure connection IF you've already changed the unit to HTTPS. If so, properly configure the browser to
bypass the proxy server for this URL. The default address is 192.168.0.1. This address must be
appropriate for your local LAN and workstation, or step 1 above must be followed.
3. Verify the IP Address Configuration
Enter the URL from step 1 (or http://192.168.0.1 if using the default address ) into your web browser. The

Chapter 3
The Conguration Process
This Chapter describes the configuration management process on the PR-6606 using a
Web Browser.
Overview
The PR-6606 contains a quite flexible configuration management system. By using this system correctly,
one can remotely configure, save copies of that configuration to a PC, make configuration changes for later
activation, and remote transfer firmware upgrades to the unit.
There may be up to three configuration “images” in use at any time.
1. The active configuration. Normally, this is the configuration that was loaded from memory when the
unit was last booted. However it may have been changed since boot time as described below. This is
the configuration that is currently running the unit.
2. The pending configuration: This is the current configuration that was loaded form memory during the
last boot along with any changes made by using the configuration screens. This configuration is
NOT the configuration running the PR-6606 at present.
3. The stored configuration. This is the configuration that was last written to the non-volatile RAM. The
next time the PR-6606 is power cycled, it will start running this configuration.
Note that any configuration transfer (with the Administration Configuration Transfer screen) is the pending
configuration. You can load a configuration file from the PC, then either activate it to test it. Or, save it
without activation if you don’t want to change the currently running configuration.
Using the Configuration Flexibility
When the PR-6606 starts from a power-off condition, it loads an active configuration from its non-volatile
memory. This active configuration is also copied to the working memory and is the “pending”
configuration.
Whenever the configuration screens are used to change values, only the pending configuration is
changed… not the active configuration.
Using the configuration screens will change the pending configuration. You may change the active
configuration by copying the pending configuration over it. This change is performed using the “Activate
Configuration” screen. Going to this screen activates the pending configuration by copying the pending
configuration over the top of the active configuration. This does not store the configuration in non-volatile
memory. When the hardware is next reset or powered up, it will begin using the old stored configuration
from before the changes were made and activate command clicked.
Using the “store configuration” screen will copy the pending configuration into non-volatile memory. It
will not cause this configuration to begin running. However, upon the next reset or power cycle, the
PR-6606 will begin using the stored configuration.
It is possible to activate the pending configuration using the Activate Configuration screen and then store
the configuration using the Store Configuration screen. This two step process will cause all three
configurations to be identical.

Configuration Process Examples
Example 1:
Make configuration changes, test them with Activate, then save them with Save.
This is the most commonly used method for changing the configuration. It allows you to test the
configuration prior to saving it. If, during the testing, you notice an abnormality; you can reset the
hardware to return to the last good configuration.
Example 2:.
Make configuration changes, save them, reset the hardware to activate the changes.
This method allows one to configure thePR-6606 via an IP network that will not work using the new
configuration. Make the changes to the pending configuration and save them. Your current session will not
be affected, but when the hardware is next powered on, it will begin using the new configuration. This
method is useful when you are configuring to use a new LAN address range while still on the old LAN.
Example 3:
Transfer a saved configuration, save it, reset the hardware to activate the changes.
It is useful to transfer an existing configuration to a PC text file for future use. Then if the hardware must
be replaced, simply transfer that stored configuration to the new hardware.
If the PC is in the default IP address range of the new hardware (192.168.0.x subnet), then a new,
out-of-the-box unit is easily configured using this method. Start the hardware on the LAN, transfer a
stored configuration file from the PC, and store it. When restarted, the PR-6606 will have the proper
configuration.
Saved Configuration Files
The saved configuration file is a simply formatted raw text file. Advanced users may wish to edit this file
using an appropriate text editor, then transfer the changed configuration to a different unit.
Use care when performing configuration with this technique as the text configuration file must be in the
proper format.
This method is ideal for automating the configuration of many units in a large corporate environment.
