The D
industrial automation applications. This chapter provides an overview of the primary feature s and
benefits of the product and describes the Terminal Server networking service.

1.1 P

The D
networking platform that is purpose-built for distributed indu s t rial automation applications such as
Supervisory Control and Data Acquisition (SCADA) system s. The DS2000-TS operates effectively in
extremely hars h environm ental conditions such as those within power utility substations, pumping stations,
treatment plants and transportati on systems. This robustness is primarily due to extended range
specifications in areas such as electromagnetic interference, te mperature, and electrical surges. Most other
networking products will fail when facing these conditions.

The DS2000-TS combines the c apabilities of an Async-to-TCP/IP Terminal Server and an IP Router in a
single inte grated device. This feature set, depicted in Figure 1-1, is used primarily in a Terminal Server
application as explained in the next section.

The DS2000-TS's device integration provides investment and operational savings compa red to alternative
solutions involving multiple less-integrated devices. Investment savings include both acquisition cost as
well as space allocation and engineering requirement s. Power system requirements are consolidated and
simplified, with the DS2000-TS supporting dir ect feeds from a wide range of DC power sour ces commonly

ECURE TERMINAL SERVER

Product Overview

1.2 T

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 seria l stream to the remo te device. In the reverse direction, Async responses from t he device are
assembled into TCP/IP packets, appropriate ly addressed and routed to the host application. More
specifically, all traffic on a DS2000-TS seria l interface is mappe d to /from an IP address and a s pecific TCP/
IP port or socket number.

Application

There are se veral variations of the Terminal Server application, describ ed in the following para graphs.

1.2.1 Local Terminal Server

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 (LA N ) . The IP host may be a
distributed application server or a PC-based HMI device at the remote site.

ECURE TERMINAL SERVER

Product Overview

1.2.2 Reverse Terminal Server

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

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

that th e DS2000-TS formulate a TCP/IP sess i on reques t to the host on behalf o f 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.

1.2.3 Back-to-Back Terminal Server

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

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

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

terminal server a llows end-to-end serial connections to be consolidated onto an al l IP -oriented network

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

this config uration , th e host end conne ction wou ld t ypical ly use an “Async-I P” con necti on ty pe, initi ating t he

TCP/IP session. T he 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 provid ed in Chapter 3.

IP Routing

1.3 IP R

The DS2000-TS includes an integral IP router capability that enables a numbe r 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 ne tw ork security using IP address filtering and IPsec encryption.

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

converts Async seria l communications to/from IP packet s. IP routing provides routing of these packets

either locally or rem otely.

The default mode for IP rout ing uses the RIP protocol to exch ange avail able rout e inf ormation wit h adjacent

routers. Advanced fe atures available with IP Routing include:

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

suppor ting Terminal S er ver traffic. Other IP R outing feat ures a re described prim arily in the re f erence

sections of Appendix B.

OUTING

• IP address filtering (sel ective blocking of permitted sources a nd destinations)

• VPNs using IPsec with DES or 3DES enc ryption

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

•

DHCP client and server (automati c assignment of IP addresses)

•

To navigate within a modifiable menu:

Use the cursor keys to move ar ound the fields

•

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

•

Press <Tab> repe at edly to get to the Pro cess selections field. Or , while in the leftmost field

•

of the screen, press t he lef t arrow ke y. This sends the curs or to th e bo ttom ri ght corner, which
is the Process selections field. The Process selections field appears on each screen where
there are modifiabl e 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 change s to F lash memory.

To change a modifiable field:

• To modify fields containing multiple toggle options, move the c ursor 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 temporar ily sets t he field to the value en tered. 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
temporar ily sets the field to t h e v alue entered. Th e change will become permanent w h en t h e
user saves the changes.

To edit input

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

•

editing characters.

2.2.3 Saving Changes

This chapter provides ideas and suggestions for troubleshooting and maintaining the DS2000-TS by
using featu r es in the Supe rvisor applic ati on. This inf orm ation is only a gui de for spec ific s ituat ion s. The
troubleshooting suggestions make reference to the Appendices that provide detailed scree n and
parameter information. The Software Maintenance section of this chapter is concerned with software
maintenance and the creation of software backups and loading new code versions.

4.1 T

The Supervisor application allows you to troubleshoot the DS2000-TS and determine the current status at
each of the following levels:

The user/operator can go into each of the listed areas to troubleshoot or verify proper operation. The
following sections discuss the above menu item s and give m enu path information to reach them, along with
cross-references to descriptions.

4.1.1 Port

The user can examine the Ports on the DS2000-TS to determine the current status, s ta tistic al details, and
monitor live traffic.

The Port Status menu provides th e current s tatus of port s on the DS2000-TS. This data is c urr en t a t th e t ime

4.1.1.2 Port Statistics

The Port Statistics menus provide a host of information for troubleshooting most port-based problems. The
informatio n on th is screen s hows the curre nt status of the port (Up or Down), Tx and Rx rates, error counts,
details on tr an smissions, an d a c omplete list of port -related data. To reach the Port Statistics menu, press
<1> Port in the Main Menu, and enter the port number: E0, CON for Console or S1 - S32 for Serial
(Async) ports, followed by <Enter>. Then press <2> Statistics. This screen displays statistics specific to
the type of port selected.

The following list e xplains where in this manual to find figures and tables describing statistics for each port
type.

• Console -Figure A-12 on page A-16, TableA-8 on pageA-16

• Serial (Async) - Figure A-11 on page A-14, Table A-7 on pag eA-14

4.1.1.3 Port Protocol Monitor

The Pro to col Moni tor shows the current data bein g transmit ted and received on any selected port to assist
you in determining the location of a fault somewhere in the network. To reach the Protocol Monitor Menu,
press, <1> Port in the Main Menu to enter the Port Menu. Next enter the port number to view (E0, CON
for Console or S1 - S32 for Serial), and press <Enter>. Then press <4> Protocol Monitor. More detail on
the Protocol monitor appears in ”Protocol Monitoring” on page A-19.

4.1.2 Network

Using Network menus in conjunction with Port statistics and status helps determine if the Routing and IP
connections are operatin g as configured. The IP Addresses and TCP/IP Status menus displ ay the ARP table,
routing table , and the connec tion s tatus of all IP-ba sed c onnect ions t o the DS2000-TS. To reac h the se m enu s
press <2> Network from the Main Menu, then <1> Router, followed by either <2> IP Routes Display or
<5> TCP/IP Status. The IP Addresses menu is shown in Figure B-5 on page B-6 and the TCP Connection
Status screen is shown in Figure B-9 on page B-10.

4.1.3 Buffer Usage

The Buffer Usage menu informs you of a possible DS2000-TS buffer resource overload due to line,
transmission, or protocol problems. Climbing In Use counts with declining Free buffer counts could be an
indication of a problem. To reach the Buffer Pool Status menu, enter <3> System from the Main Menu,

Figure 4-1. BOOT Process Example

After initia ting the boot process, the system temporarily halts for 20 seconds. The reason for pausing is to
provide the ability to configure the DS2000-TS if no runtime operating system has been loade d. In
particular, the pause provides an opportunity to set an initial IP address for downloading software and
establishi ng Telnet command sessions. If an op erati ng system already exists , then pre ssing <Esc> before the
end of the 20-s econd pause will resume the boot process. If no key is pressed and 20 seconds elapses, the
system will boot automatically.

This com pletes the boot process and the screen will display the opening banner and login menu. The current
contents of the event log are the last part of the boot process and can be useful in diagnosing boot problems
in the unli kely event t he system fails to boot.

NITIALIZING AN

If an ope rating sy stem doe s not already exist, then you must establish the “Local/ROM Address” during the
Boot process. The “Local/ROM Address” requires an IP address assigned to it in order to rem otely
download software to the Super visor and/or permit SNMP communica tions with the DS2000-TS. If the
system is already running under an operating system, assignment of the Local/ROM Addre s s is th rough the
console command menus. (Refer to ”Assign IP Addresses And Protocols” on page B-5.) If no operating
system exists on the DS2000-TS, execute the Boot process as de scribed in ”Boot Process” on page 4-3. The
Boot process will pause for 20 seconds right after the following message appears:

Current IP address is 0.0.0.0

During this time, the Console displays a prompt to enter an IP address. The IP assignment allows IP
applications like TFTP and Telnet to communicate with the DS2000-TS from a remote location in order to
make configur ati on changes and/or upgrade the Operating System to a newer version.

Enter different IP address:

The IP address can be entered in a normal IP address format e.g. 100.1.1.1 <Enter>. The system displays a

OFTWAREMAINTENANCE

To dis cuss the software maintenance tasks it is important that the user understand how the system operates.
A description of the software files is also required. For descriptions of the files stored on the system and
restarting methods refer to Appendix C, “System Functions” before continuing.

The system softw are resides in Flash memory on the D

factory, will includ e Download.bin and if the system has been in operation, then the SRAM1 and SRAM2
files will also be present. The SRAM files will appear after configurations are made in the unit. The
Download.bin file is the decompressed operational software loaded on the system at the factory. The SRAM
files are copies of memory that contain the current and previous configurations. The SRAM acts as a
temporary notepad to write s ystem changes. When a <CTRL-W> Flash save operation is performed, the
system copies the current SRAM to Flash thereby changing the active configuration of the DS2000-TS. The
other SRAM contains a copy of the last configuration. In this way the SRAMs maintain copies of both the
current and last configurat ions. As an example, a user on a DS2000-TS makes changes to the configuration
without saving the changes to Fla sh. These changes are resident on one of the SRAMs, for this example let
us assume SRAM1. Warm restarting the DS2000-TS flushes SRAM1, and SRAM2 becomes the active
notepad. T he changes made and not saved to Flash are lost, and the SRAM2 now contains the current
configuration information for the system.

The Download.bin file, which is the operational software, will also have a version number associated with it
and sho wn in the Dir ectory Manag ement men u . The version w i ll also have a Bui ld num b er in parenthesis,
such as (RC47), this designates the numerical sequenc e of the file creation, therefore the higher the build
number the newer the software within each version. There can be up to two Download.bin files on the
system at any one time. Attempting to add a new Download.bin file will not be allowed by the system. The
system renames the software load saved to the system to DOWNLOAD.BIN. The software file loaded is
named alfload.bin and when saved to the system the system rena mes it DOWNLOAD.BIN.

The cnfgload.cmp file is a compressed file containing the con fi guration data from the DS2000-TS. This file
is created to maintain a backup of the configured s ystem should it become ne cessary to restore this
configuration on a replacement system and also to reinitialize a system to and maintain the desired
configuration. The reinitialize restart type will only be present (shown to the user) if a cnfgload.cmp file is
present on the system. It should be observed that there is no information shown to the user about when or
what version of softwar e the cnfgload.cmp file was created under. The cnfgload.cmp file must be generated
by the user by issu ing a GET command, CHECK THISusing TFTP (Trivial File Transfer Protocol) or FTP
(File Transfer Protocol), to the D

2000 which then create s th e file. When the DS2000-TS receives

the GET cnfgload.cmp command it creates the file and sends it to the requestor, but does not store it on the
system. This file is the co mplete configuration of the system as entered by the use r. To place the
cnfgload.cm p configuration on the system the user must place the file on the system using either the
appropriate TFTP PUT or FTP PUT command. To utilize th e cnfgload.cmp configuration the user Boots the
system usi ng t he reinitialize command. During the Re initialize Boot, the s ystem sees the cnfgload.cmp file
in Flash and uses it to rebuild the configuration data. Refer to t he release notes on any software upgrade to
ensure that the configuration data is portable to the newer version. There are two methods for transf erring
files to the D

The FTP facility allows standard FTP clients to connect to the D

YNASTAR

2000 FTP host system using a

command line interface (CLI) such as MicroSoft DOS command window, Unix, or Linux. This facility is
restricted to line-by-line command input mode. Not all of the standard FTP commands are supported on the

D

YNASTAR

2000. FTP works by entering the “ftp IP a ddress” string from a client FTP work station. When

the receiving h ost sees its IP address, it asks for the User Name and Password. The user name and password
are the same as the user names alr eady designated on the system. Once accepted the user is logged into the
system and can perform get and put commands . Note that the use r is logged into the system and should quit
or disconnect the session when tasks are completed. The system will timeout after a short interval of
inactivity. The following commands are supported: (Note that the user entered parameters are in italics.)

ftp Entering FTP followed by the remote server’s IP address starts a client FTP

session on the remote server. The server will then prompt t he us er for a user nam e
and password.

ftp connection example:

c:\localdirectory\user> ftp (IP Address of Dynastar host)
Connected to 10.0.0.1
220 Connected to DY MEC ftp Server.
User (10.0.0.1:(none)): (Enter the User Name - Root is default)

user Used to change the user, while connected in an FTP session, on the remote server.
ascii Sets the file transf er mode to ascii. Entering ascii from the ftp> prompt sets the

transfer mode. T he server will respond with a 200 Command Okay. Note that all

file transfers to the D

YNASTAR

2000 must be in binary mode.

binary Sets the file transfer mode to binary (bin). Entering bin from the ftp> prompt sets

the transfer mode. The server will respond with a 200 Command Okay. Note that

all file transfers to and from the D

YNASTAR

2000 must be in binary mode.

get Gets a r emote file from the re mote host to the local client. No te that the user

password is also required following the name of the file being retrieved from the

remote host. The get command syntax is:

ftp> get filename/password filename

Where:

get (retrieve a file from a remote host)
filename (nam e o f file on the remote host)
password (the user’s password)
filename (name of file being sto r ed on the loca l sy s tem, files can be

renamed as they are stored)

4.4.2 TFTP Commands

There are various TFTP packages available and the syntax varies. The following syntax and command
structure is used in this manual for TFTP commands:

TFTP [-i] host [GET | PUT] source [filename] destination [filename]

-i Specifies bi nary image transfer. I n binary image mode the file is moved byte by

byte. Use this mode when tr ansf erring binary files.
host Specifies the remote host (i.e. 192.168. 42.5)
GET Retr ieves the file source from the remote source and saves the file in the current

local directory
PUT Sends the file source on the local host to the file destination on the remot e hos t
source Specifies the file to transfer
destination Specifies the destination for the transferred file

4.4.3 Creating a Compressed Configuration File

A compressed configuration file is created to store the current configuration of the D
event that a new system is required or a new softwa re build is implemented. When the cnfgload.cmp file is
present on the system, and the system is initiali zed, the cnfgload.cmp file will be used to configure the
system. This saves the time required to re-enter the user configurable parameters. This section describes
using F TP a nd TFTP co mmand s t o “ get ” a nd cr eate a c omp res sed cnfgload.cmp file on a DS2000-TS. When
the DS2000-TS receives a GET cnfgload.cmp command it creates the file and sends it to the requestor
without saving it to local memory. Once received, it is recommended that this file be saved elsewhere for
contingency purposes, approp riate ly label ed to indic at e its origin an d any other infor mation to help a system

4.4.4 Placing a Compressed Configuration File on a

Placing a compressed configuration file on the DS2000-TS is helpful when upgrading system software or
regressing to a previous build. The system uses the compressed configuration file to rebuild the old
configuration during the processing of the new operating s ystem. Ensure that the configuration file used is
the cor rect file created from the current co n f iguration of t he DS2000-TS since this file will recreate the IP
addresses on the new opera ting system.

CAUTION: Rebooting the system using a configuration file with unknown passwords and IP
addresses will lock everyone out of the system when the boot and reconfiguration is
completed. Ensure that the passwords are known for the cnfgload.cmp being used.

The DS2000-TS requires that the name of the downloaded c ompressed configuration file be cnfgload.cmp.
Correc t sp elling is mandato ry. Us e either FTP or TFTP commands to PUT the file on the DS2000-TS. The
user must then reinitialize the system using the required software build. If there is no cnfgload.cmp file on
the system then the reinitialize feature is not shown to the user. When the system begins to process the new
software build it will use the cnfgload.cmp file to restore the sys tem parameters to those saved in the
configuration file.

NOTE: If there are multiple copies of the cnfgload.cmp on the DS2000-TS, the system will

&

&

&&

use the latest version to restore the configuration.

If usin g FTP to place the cnfgload.cmp file use the following steps: (refer to ”F TP Commands” on page 4-6
for details on FTP commands.)

1. Start an FTP session on the D

IP address of the D

2. Put the cnfgload.cmp file on the remote D

further actions. To get to the Directory Management Menu enter <3> System in the Main
Menu, then press <1> Code Versions to display the Directory Management Menu, this menu is
shown in Figure C-3 on page C-3.

4. Ensure that the cnfgload.cmp is present with the correct date and timestamp before reinitializing

the system.

4.4.5 Placing a Software Load on a

This section describes pla cing an op e r ating system on a DS2000-TS. One file, obtained from Dymec Inc.,
named alfload.bin contains the operating system for the DS2000-TS. The system renames the alfload.bin
file to download.bin while writing the file to the DS2000-TS. The system also checks the file to determine if
it is an appl ic abl e lo ad for the DS2000-TS. The system recogni zes the fi le and d isplays the build and version
numbers on the Supervisor menu system. Check the operating system loaded onto the DS2000-TS for
proper version and build numbers before booting the system with that load.

NOTE: The system can only store two versions of the operating system. If two are already

&

&

&&

present on the

4. Ensure that the alfload.bin is present with th e co rrect date a nd t ime st amp before restarting the

system.

If using TFTP, perform the follow ing steps to load the new operating system. Refer to ”TFTP Commands”
on page 4-7 for the syntax and command structure used in the following steps.

1. U se the TFTP PUT c om mand to place the file on the DS2000-TS.

tftp -i 192.168.10.10 put alfload.bin alfload.bin

This will take a few mome n ts depen ding on the access speed

2. With the file received, go into the Supervisor m enu system and verify the proper load is present.

Note the file name is changed to download.bin by the system with a build number associated with
it. The path is as follows: press <3> System from the Main Menu, then press <1> Code Versions

3. Check that the correct load is present on the system by verifying the version and build numbers of

the new download.bin file . If the system configurat ion is not goi ng to change , a good practice is to
create a new cnfgload.cmp file and put it on the sys tem prior to using a new software build. This
will take a few moments depend in g on the access speed. Refer to ”Creating a Compressed
Configuration File” on page 4-7 and ”Placing a Compressed Configuration File on a DS2000-TS”

4.4.6 Reinitializing the System

This section deals with booting the system using a new software build while maintaining the current
configuratio n on the sy stem. This proce dure is also used to fa ll ba ck to a pre vious load of software shoul d an
upgrade have unexpected results. Use the Supervisor menu system to reinitialize the DS2000-TS. You must
have loaded the new operati ng syste m and ver ified th at a curr ent confi gurati on (cnfgload.cmp) file is pres e nt
on the DS2000-TS before attempting to reinitializ e.

Although the system has enough memo ry space for several versions of oper ating sys tems, onl y two versions
are accessible using the reinitialize feature in the Supervisor menu system. If there are more than two
versions of the operating system on the DS2000-TS, remove the oldest from the system prior to using a new
version. This protects the system in case there is some error with a new build. If there are three versions of
the operating system prese nt on the system and there is a fault or error usi ng the newest build, then you will
be required to fall bac k to the previous version. This will not be possible using the reinitialize feature as the
system only shows the oldest and n ewe st vers ions of the operating system to you. Perform the following
steps to reinitialize the DS2000-TS.

4. Place the cursor over the Restart Type field and press <Enter>. This is a toggle field and if the

cnfgload.cm p file is present then the Reinitialize option will be displayed.

5. Mov e down a line in t he men u to the Code Version field and press <Enter> to sel ect the versi on of

the software to load.

6. Move down to the next field named Password and enter the Root password for the DS2000-TS.

7. Move the cursor to the Proces s selections fi e ld and press <Enter>. The system will become

unavailable while loading the new operating system and restoring the old configuration. Wait
approximately one minute before attempting to reestablish contact with the DS2000-TS.

8. Upon reestablishing contact, you should go through the menus and verify proper port operation

and restoration of communications.

4.4.7 Deleting Files from the

It is recommended that the user actively manage the files stored on the DS2000-TS. As previously
discussed, the system can ma intain two versions of the operating syste m and numerous ve rsions of the
cnfgload.cmp files. The number of cnfgload.cmp files is not important since the system only uses the latest
version; however, seeing multiple ve rsions of the same file with varying timestamps can be confusin g. As
only the current version is r equired, older versions can be safely deleted. Th e following steps describe
deleting a file from t he system using the Supervisor menu application.

1. Open the Directory Management menu by selecting <3> System in the Main Menu and then

<1> Code Versions. The Directory Management menu opens, as shown in Figure C-3 on page
C-3.

2. De te rmine the fil es to era se and t oggl e the values, which toggl e from N (n o) to Y (yes) . Toggle this

field to Y to select files for deletion.

3. Scroll down to the Defragm ent Flash M emory field. If an op erating sy stem file , download.bi n , is

being deleted then it is recommended that you toggle this value to Y. Otherwise it is not required.

4. Scroll down to the Enter password to erase files field and enter the Root password for the system.

When the correct password is entered the files selected will be erased i t may take a moment for the
system to defragment the system if that has been sel ected.

This selection allows the administrator to shut down, turn on, and initialize all connections on the DS2000­TS. This function is on a port-by-port basis and must be instigated one port at a time. From the M ain Menu,

select <1>Port, select a port, and s elect <3> Disable/Enable. Select in g the Disable/Enable option displays
the menu shown in Figure A-13.

The Port Activation menu shows the current status of the port. To change the current status press the
<Enter> key; this toggles the Action field through the possible actions. The actions are Di sab le, Enable,
Busy, or Initialize based on the current state of the port. Use care not to Disable the port which the
Supervisor connec tion is being made on. This will cause a n immediate loss of contact and a new Supervisor
connection will have to made through another port. Initia lizing the port being used for a Supervisor session
will cause a momentary interruption and the user will have to log ba ck into the DS2000-TS but the
connection will return.

There are three possible current states for ea ch port. They are Enabled, Disabled, or Bu sy. Note that Busy
will prevent any new connections to the port but will not cancel current active connections.

To change the current status of the port or to initialize a po rt, toggle the Action variable to the correct setting
and move the cursor over the Y in the Process Selections entry at the bottom of th e menu. With the cursor
over the Y press the Enter key. This will activate the action selected. When disable is se lected, a Warning

B.2 R

The DS2000-TS has an e mbedded IP router function used for connecting the DS2000-TS Supervisor
application to an IP network for remote operator access an d f o r re m ot e access to SNMP traps and operating
software downloads. The routing function may also be used by the other devices connected to the DS2000-
TS for routing traffic beyond their specific bridged group. The IP routing function is useful for networking
of telemetry, Telnet and other moderate bit rate applications to/from connected devices. In particular, the
routing function may be useful for allowing a single system operator to have Telnet supervisory acces s to a
number of remote devices which otherwise are segregated into different groups with no facility for cross­group communications.

One key de cision in configuring DS2000-TS IP routing is to set the scope of access to the routing function.
By default, all Ethernet ports are in one group, share the assigned system IP address and have access to the
routing function for routing outsi de their bridged network. Individual ports may be disabled from the IP
routing function by using the Ethernet Switch Port Configuration screen described Appendix A, “Port
Functions”. Routing may be further restricted using the IP Filter feature s desc ribed in “IP Filters” on page
B-7. When Por t-based groups are used and you want these specific groups to participate in IP routing, IP
addresses must be ass ig ned separat ely for each g roup, as desc r ibed below. There are no defaul t IP addresses
for groups and ports assigned to groups will not be able to route (except to the DS2000-TS Supervisor) until
a group IP address is ass igned.

A second key decision is to define the ro ut i ng protocol. By default, route d ports are defined to use RIP as
their routing protocol. The other option is Static Routing. (OSPF is not available on the DS2000-TS.) Each
of these requires filling in additional configuration screens.

In addition to basic IP routing, the DS2000-TS also supports BootP Helper and DHCP Server functions to
assist devices that are attached to the DS2000-TS in obtaining IP addresses and other parameters required
for the opera tion. BootP and DHCP functions are configured in the DS2000-TS as part of this IP Router
section.

This screen is used to define one static route per line of the table. Up to 120 static routes can be configured.
For each route, enter the following information on a single line:

• In the IP Address column, enter the IP address of the remote network.

• A default mask appears. If required, modify the IP mask for subnetting.

• Note: A static route of 0.0.0.0 can be used as a default route for routing any IP

address that does not have a match in the routing table.

• Under Next Hop, enter the IP address of the remote IP port used to access th e IP ne twork

specified in this procedure. This will generally be the IP address of a router directly
connected to the same switched Ethernet netw ork, but not necessarily directly attached to
this DS2000-TS.

• In the Hops colu mn, enter the number of hops to the remote network using this static route.

• If the number of hops entered here is greater than the number of hops in a dynami c

route (using RIP) to the same IP net work, then the dynamic route will be used.

• When you have completed your configuration, enter Y in the Process Static Routes field

and press <Enter>.

After entering IP routes, it is a good prac tice to verify the routing information. From the Main menu, select
<2> Network, <1> Router then <2> IP Routes Display. These are described in the previous section.

B.2.6.1 BootP Client/Helper

The DS2000-TS can act as a BootP relay agent to transfer BootP messages between clients and servers.
BootP (Bootstrap Protocol or Boot Protocol) provides to the requesting device the path and filename of its
bootstrap file, as well as its default router, its own IP address, and the BootP server’s IP Address. BootP
sends its messages in UDP headers enclosed in IP datagrams. In many cases, BootP clients and their
associated BootP server(s) do not reside on the s ame IP network or subnet. The actua l BootP server can be
several hops away from the BootP client system. In such a case, an DS2000-TS can act as a relay agent to
transfer BootP mess ages between clients and servers. To configure the DS2000-TS to act as a BootP relay
agent follow the procedure below , select <1> Client Configuration as described above. The screen, shown
in Figure B-11, will appear. The remote IP addresse s of up to three remot e BootP servers may be specified.

B.2.7 Virtual Private Networks

The Virtual Private Network (VPN) allows organizations to use s ervice provider networks for secure
exchanges wit h remote of fi ces, v endors , and pa rtners. VPN authentic ate peer systems an d opt ionall y encryp t
transmissions using key exchanges, hashing, and encrypt ion algorithms.

The DS2000-TS implementati on of the VPN conforms t o IPSec RFC 2401 (using DES and T riple DES) and
provides VPN solutions for both site-to-site (router-to-router) and remote access VPN deployments.

IPSec pr o vides secur it y services at the I P layer by enabling a s ys tem to select required se c ur ity proto cols,
determine the algorithm(s) to use for th e service(s), and set up any cryptographic keys required to provide
the requested services. IPSec can be used to protect one or more “paths” between a pair of hosts, between a
pair of security gateways, or between a security gateway and a host. The following sections describe the
VPN configuration and status screens.

B.2.8 TCP Multicast

The DS2000-TS supports a broadcast fe ature t hat lets the user configure TCP multicast groups. A maximum
of 50 TCP sources can be defined, which can connect to a maximum of 60 destinations. Traffic received on
the source IP address and socket is sent to each of the destinations; any traffic received on the destinations is
sent only to the source. When a user conne cts to the source IP address and socket, TCP connections are
automatic al ly laun ched to th e des t inati ons . If a desti nat ion is cle are d, the DS2000-TS attempts to reestablish
the connection e v ery 10 s econds. I f th e source is cleared, all destinations are cleared.

The source must be configure d first ; th is is done by de fining a Mult icast a sync se rvic e type . The des tinat ions
are configured from the Multicast Destina tions screen, which is found under <2> Network, <1> Router,
<10> TCP Multicast. The Multicast Destinations screen is shown in Figure B-19.

B.4.1 PAD Profiles

Profiles are predefined s ets of X.3 parameters that are designed to be used with specific types of
asynchronous dev ices. Each profile is identified by a numbe r and, optionally, a name. The DS2000-TS has
two built- in p rofiles defin ed b y the IT U-T tha t cann ot be c hanged: the tr ansparen t pro fil e (91) an d the s impl e
profile (90). There are an additional 14 profiles (numbered 76 through 89) that you can confi gure. Five of
these profiles are predefine d: one for display devices (CRT), one for printing terminals (TTY), one for
T elnet clients (TELNET), one for an X.29 set command for a LAN (LAN) and one set up for SCADA traffic
(85). The remaining profiles are set to default values that match the CRT profile.

For convenience, all profiles can be referenced by a second set of numbers, from 1 to 16, as indicated on the
PAD Profiles screen.

The Async Port Configuration screen (see Figure B-24) lets you define an X.28 profile (local profile) and
an X.29 profile (remote profile) for the port you are configuring. The values in the X.28 profile govern the
internal operation of the local PAD port.

The X.29 profi le, if de fine d, governs the oper ati on of the remote PAD port. When a call is initiated, the loca l
PAD port sends an X.29 data packet to the device at the distant end requesting a change in the X.3
parameters to match the profile listed in this field.

You can temporarily override the local profile set for your port with the X.28 PROF co mmand, and you can
use the X.28 SET or SET? commands to temporarily change individua l X.3 parame ters.
