DYNASTAR 2000 SECURE TERMINAL

SERVER

The DYNASTAR 2000 SECURE TERMINAL SERVER is a purpose-built networking platform for distributed

industrial automation applications. This chapter provides an overview of the primary features and

benefits of the product and describes the Terminal Server networking service.

The DYNASTAR 2000 SECURE TERMINAL SERVER (DS2000-TS) is a multi-function, multi-protocol

networking platform that is purpose-built for distributed industrial automation applications such as

Supervisory Control and Data Acquisition (SCADA) systems. The DS2000-TS operates effectively in

extremely harsh environmental conditions such as those within power utility substations, pumping stations,

treatment plants and transportation systems. This robustness is primarily due to extended range

specifications in areas such as electromagnetic interference, temperature, and electrical surges. Most other

networking products will fail when facing these conditions.

The DS2000-TS combines the capabilities of an Async-to-TCP/IP Terminal Server and an IP Router in a

single integrated device. This feature set, depicted in Figure 1-1, is used primarily in a Terminal Server

application as explained in the next section.

CHAPTER 1 - DYNASTAR 2000 SECURE TERMINAL SERVER Product Overview

Terminal Server Overview

DS2000-TS Administrator’s Guide

1 - 2

The DS2000-TS's device integration provides investment and operational savings compared to alternative

solutions involving multiple less-integrated devices. Investment savings include both acquisition cost as

well as space allocation and engineering requirements. Power system requirements are consolidated and

simplified, with the DS2000-TS supporting direct feeds from a wide range of DC power sources commonly

used at industrial sites. Operational savings come from reduced maintenance and administration, including

having fewer different software-based devices to coordinate for network configuration, diagnostics and

software upgrades.

The DS2000-TS Terminal Server feature is typically used to enable a host-computer application based on

TCP/IP protocol to communicate with remote industrial devices that have an Async serial network interface

(see Figure 1-2). All communication is in IP-format from the central host to/from the remote site. The

DS2000-TS Terminal Server feature at the remote site disassembles each TCP/IP packet and provides an

Async serial stream to the remote device. In the reverse direction, Async responses from the device are

assembled into TCP/IP packets, appropriately addressed and routed to the host application. More

specifically, all traffic on a DS2000-TS serial interface is mapped to/from an IP address and a specific TCP/

IP port or socket number.

Figure 1-2. Local Terminal Server

There are several variations of the Terminal Server application, described in the following paragraphs.

This is the typical application involving a local IP-host, i.e., a host collocated with the serial devices and

attached to a DS2000-TS port either directly or via a Local Area Network (LAN). The IP host may be a

distributed application server or a PC-based HMI device at the remote site.

CHAPTER 1 - DYNASTAR 2000 SECURE TERMINAL SERVER Product Overview

IP Routing

DS2000-TS Administrator’s Guide

1 - 3

This application has the same physical topology as the Local Terminal Server, but the communications

connection is initiated on-demand by the Serial device, rather than by the host application. This requires

that the DS2000-TS formulate a TCP/IP session request to the host on behalf of the serial device. In the

DS2000-TS, this is configured as an “Async-IP” terminal server connection, as differentiated from the more

common and default “IP-Async” terminal server connection.

This application uses two Terminal Server capabilities at both the host end and async-device end of the

connection, providing serial interfaces to both the host system and remote device. The devices may be

attached to the same DS2000-TS or to different DS2000-TSs connected over a network. Back-to-Back

terminal server allows end-to-end serial connections to be consolidated onto an all IP-oriented network

infrastructure, keeping with the spirit of “IP Convergence,” at least at the transport layer of the network. In

this configuration, the host end connection would typically use an “Async-IP” connection type, initiating the

TCP/IP session. The other industrial device would be connected to a DS2000-TS using the default “IP-

Async” Terminal Server as described above.

The principal variant of Terminal Server used with the DS2000-TS is the Local Terminal Server.

Configuration guidelines for this service are provided in Chapter 3.

The DS2000-TS includes an integral IP router capability that enables a number of applications and

enhancements to reliability and security.

IP Routing can be used locally within a site. Local routing is an alternative to layer-2 Ethernet switching

among Ethernet ports. IP routing provides communication among devices in different Ethernet VLANs and

can provide additional network security using IP address filtering and IPsec encryption.

IP Routing is also used by the Terminal Server application described above. The Terminal Server feature

converts Async serial communications to/from IP packets. IP routing provides routing of these packets

either locally or remotely.

The default mode for IP routing uses the RIP protocol to exchange available route information with adjacent

routers. Advanced features available with IP Routing include:

•IP address filtering (selective blocking of permitted sources and destinations)

•VPNs using IPsec with DES or 3DES encryption

•Static routing (explicit next hops, not using a routing protocol like RIP)

•DHCP client and server (automatic assignment of IP addresses)

The Configuration Basics described in Chapter 3 deal primarily with default IP routing using RIP,

supporting Terminal Server traffic. Other IP Routing features are described primarily in the reference

sections of Appendix B.

CHAPTER 1 - DYNASTAR 2000 SECURE TERMINAL SERVER Product Overview

DS2000-TS Management Features

DS2000-TS Administrator’s Guide

1 - 4

This section provides summaries of selected management capabilities for all DS2000-TS services.

Chapter 3 provides details on the DynaStar Supervisory application. This menu-based management

application supports configuration, diagnostics, performance monitoring and security functions for the

DS2000-TS. The Supervisor is accessed over the local console port or remotely via an IP network.

The DS2000-TS has a number of visual alarm and status indicators implemented as LEDs on the wiring

panel of the device. There is also an alarm port that provides a hard contact status indication of major system

failure.

The DS2000-TS provides an SNMP MIB interface for status, statistics and provisioning. Alarms may be

formatted as SNMP traps to central network management systems.

A number of security options are available for management interfaces to the DS2000-TS. Management

access security includes both logical access (e.g., IP address filtering, IPsec/VPN), and multi-level password

protections. Management data may be encrypted using IPsec with DES or 3DES.

UPERVISOR

This chapter provides an overview of the management application included in all DynaStars to

configure, administer, and troubleshoot the equipment and the network. The following sections

introduce the management application, describe access and login procedures, provide navigation

details and common commands, outline the menu hierarchy, and provide an overview of the supervisor

capabilities.

This chapter also describes a number of standard tasks associated with the administration of the

DYNASTAR 2000 SECURE TERMINAL SERVER in particular. These standard tasks are general in nature

and not dependent on any particular configuration of the network or interfacing equipment.

The Supervisor application running on the DS2000-TS manages the device. The Supervisor application is a

hierarchical menu-driven system allowing users to manage and configure the DS2000-TS. Through the

supervisor application, the user can configure ports, services, and features; view statistics; carry out

maintenance activities and perform troubleshooting. The Supervisor application is accessible through the

local console port or by using Telnet to connect to the DS2000-TS from the network.

This section describes the command notation used in this manual and the methods for navigation within the

Supervisor, along with how to select configuration settings, enter or modify data, and save changes.

This manual uses the following notations and conventions:

•The names of keys are bold and contained in angle brackets, for example <Enter>

•Two keys pressed simultaneously appear in angle brackets separated by a hyphen (i.e.

<CTRL-D>)

•Commands you must enter appear in italics

•The names of menu fields also appear in boldface

•Representative text in a command line appears in italics. For example, the word filename

indicates that an actual filename should replace the italicized word.

•System messages appear in italics

CHAPTER 2 - Supervisor Overview

Universal Commands For Supervisor Menu Navigation

DS2000-TS Administrator’s Guide

2 - 2

To navigate down to a submenu:

•Type the command number and press <Enter>.

- or -

•Use the cursor keys (left, right, up and down arrows) to move to the desired function, and

press <Enter>.

To return to a previous menu:

•Press the <Esc> key.

- or -

•In menus with no modifiable fields, pressing the left arrow will display the previous menu.

To navigate within a modifiable menu:

•Use the cursor keys to move around the fields

•Use the <Tab> key to send the cursor to the next modifiable field.

•Press <Tab> repeatedly to get to the Process selections field. Or, while in the leftmost field

of the screen, press the left arrow key. This sends the cursor to the bottom right corner, which

is the Process selections field. The Process selections field appears on each screen where

there are modifiable parameters and is used to save the changes to volatile memory.

Although selecting Y and pressing <Enter> in the Process selections field saves the

changes, the user must also save the changes to Flash memory.

To change a modifiable field:

•To modify fields containing multiple toggle options, move the cursor with the arrow keys or

<Tab> key until it is in the field to be modified. Pressing <Enter> toggles the parameter to

the next option. Pressing the <Enter> key repeatedly cycles through all the field options.

Moving out of the field temporarily sets the field to the value entered. The change will

become permanent when the user saves the changes.

•To enter information in a text or number field, place the cursor in the field and type the

desired information. Moving the cursor out of the field stops editing the data field, and

temporarily sets the field to the value entered. The change will become permanent when the

user saves the changes.

To edit input

•The Supervisor Console is preconfigured to use the <Backspace> and <Delete> keys for

editing characters.

Before a change can be saved to Flash memory it must first be processed. This adds the information to the

system from which the Flash memory is updated. The Process selections field is in the lower right corner of

all modifiable menus. To process the changed configuration information, move the cursor to the Process

selections field. The Process selections field should contain a <Y> but if it is <N> type in the letter <Y> and

press the <Enter> key. If the user does not wish to save the changes made, either press <Esc> to go back to

the previous menu, or type <N> in the Process selections field and press <Enter>.
