Prestige 100L IDSL Router

Chapter 1

Getting to Know Your Prestige

This chapter introduces the main features and applications of the Prestige.

1.1 The Prestige 100L IDSL Router

The Prestige 100L is the perfect IDSL Client for the Prestige 1600, offering inexpensive yet complete
telecommunications and internetworking solutions for your home or branch office. The Prestige is ideal for
everything from Internet access, LAN-to-LAN connections or Remote Access. ZyXEL’s Prestige 100L
provides not only ease of installation and Internet access, but also a complete security solution to protect your
Intranet and efficiently manage data traffic on your network.

1.2 Features of the Prestige 100L

The following are the essential features of the Prestige 100L.

ISDN Digital Subscriber Line (IDSL)

IDSL is a digital subscriber service that uses a subset of the existing ISDN standard. It offers speed up to 128
kbps over a single twisted copper pair wire for distance up to 18,000 feet. Because IDSL uses the same
standard as ISDN, users can use the existing ISDN terminal adapters, routers and bridges for IDSL
connections. IDSL is the easiest and the least expensive to deploy among DSL technologies since a majority
of the local loops are “ISDN-ready” and thus “IDSL-ready” as well.

Full Network Management

The Prestige incorporates SNMP (Simple Network Management Protocol) support and menu-driven network
management via an RS-232C or telnet connection. All functions of the Prestige 100L are also software
configurable via the SMT (System Management Terminal) interface. The SMT is a menu-driven interface
that you can access from a terminal emulator through the console port or over a telnet connection.

PPP Security

The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol).

Dynamic Host Configuration Protocol (DHCP)

DHCP allows you to assign dynamically and automatically IP address settings to hosts on your network.

Data Compression

The Prestige incorporates Stac Data Compression and Compression Control Protocol.

Getting to Know Your Prestige 1-1

Prestige 100L IDSL Router

Internet Access

The Prestige supports TCP/IP protocol. It is also compatible with other IDSL access servers manufactured by
vendors such as Ascend.

Single User Account (SUA)

This allows multiple users to access the LAN simultaneously using a single IP address. SUA address
mapping can also be used for LAN to LAN.

Integrated 4-Port Ethernet Hub

The Prestige is equipped with a built-in 4-port Ethernet 10Base-T hub. The built-in hub eliminates the need
to purchase a separate hub when building a one to four-port network. For a larger number of workstations,
additional hubs can be daisy-chained to the Prestige.

Upgrade Prestige Firmware via LAN

You can upgrade the Prestige firmware over the local LAN.

2-2 Hardware Installation and Initial Setup

Prestige 100L IDSL Router

This section outlines how to connect your Prestige 100L to the LAN and the IDSL line. Refer to the above
diagram to identify all of the ports on your device when you attempt to make the various connections.

NOTE: The IDSL line and Ethernet cable are very similar to each other. It is important

that you use the correct cable for each connection; otherwise, your Prestige could be

damaged.

Connecting Your Computer and Your Prestige

For the initial configuration of your Prestige, use the provided RS-232C cable and communications
software to configure your Prestige. After your Prestige has been successfully installed, you can modify the
configuration through a console port as well as a remote telnet connection.

Step 1. Connecting an IDSL Line to Your Prestige
Plug one end of the IDSL line included in your package into the socket on the rear panel of your Prestige

labeled LINE, and the other end into the IDSL wall jack or another Prestige.

NOTE: The IDSL jack is for IDSL line connection only. Connecting it to a regular phone

line may result in damage to your Prestige.

Step 2. Connecting the RS-232C Cable to Your Prestige
One 9-25 pin adapter is included with your Prestige. To connect an RS-232C cable, connect the 9-pin end

of the cable to the console port on the back panel of the Prestige. Connect the other end to the RS-232C
cable connected to the serial port (COM1, COM2, or any other COM port) of your computer.

Step 3. Connecting an Ethernet Cable to Your Prestige
The Prestige is equipped with a 4-port hub for you to build a 10Base-T Local Area Network (LAN).

10Base-T networks use UTP (Unshielded Twisted Pair) cable and RJ-45 connectors that look like a bigger
telephone plug with 8 pins. Two types of Ethernet cables come with the package:

l Straight through cable (white tag) — connect your computers to your Prestige.
l Crossover cable (red tag) — connect your Prestige to another 10Base-T hub.

Step 4. Connecting the Power Adapter to Your Prestige
Connect the power adapter to the port labeled POWER on the rear panel of your Prestige.

CAUTION: To prevent damage to the Prestige, first make sure you have the correct AC

power adapter specifications (refer to the Appendix section) for your particular

region.

At this point you should have connected the RS-232C cable, the ISDN phone line, the Ethernet cable, and
the power supply.

Step 5. Powering On
You can now power on your Prestige.

2.3 Housing

Your Prestige's ventilated housing has clip-out legs that fit snugly into grooves, enabling compact, sturdy
stacking with airflow between routers. You should not stack more than 4 routers for maximum stability.

Chapter 3

Internet Access

This chapter shows you how to configure the LAN as well as the WAN of your Prestige for Internet

access.

3.1 TCP/IP and DHCP for LAN

The Prestige has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that
support DHCP client capability.

3.1.1 Factory LAN Defaults

The LAN parameters of the Prestige are preset in the factory with the following values:

1. IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits).

2. DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.

These parameters should work for the majority of installations. If the parameters are satisfactory, you can
skip to the later section of this chapter to enter the DNS server address(es) if your ISP gives you explicit
DNS server address(es). If you wish to change the factory defaults or to learn more about TCP/IP, please
read on.

3.1.2 IP Address and Subnet Mask

Similar to the houses on a street that shares a common street name, the machines on a LAN share one
common network number, also.
Where you obtain your network number depends on your particular situation. If the ISP or your network
administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP
addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single user account
and the ISP assigns you a dynamic IP address when the connection is established. If this is the case, it is
recommended that you select a network number from 192.168.0.0 to 192.168.255.0 and you must enable the
Network Address Translation feature of the Prestige. The Internet Assigned Number Authority (IANA)
reserved this block of addresses specifically for private use; please do not use any other number unless you
are told otherwise. Let’s say you select 192.168.1.0 as the network number; which covers 254 individual
addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first 3 numbers
specify the network number while the last number identifies an individual workstation on that network.
Once you have decided on the network number, pick an IP address that is easy to remember, e.g.,

192.168.1.1 (default), for your Prestige. If you chose this then the other default settings are enabled.

Internet Access 3-1

Prestige 100L IDSL Router

The subnet mask specifies the network number portion of an IP address. Your Prestige computes the subnet
mask automatically based on the IP address that you entered. You do not need to change the subnet mask
computed by the Prestige unless you are instructed to do otherwise.

3.1.3 Private IP Addresses

Every machine on the Internet must have a unique address. If your networks are isolated from the Internet,
e.g., only between your two branch offices, you can assign any IP addresses to the hosts without problems.
However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP
addresses specifically for private networks:

10.0.0.0 - 10.255.255.255

172.16.0.0 - 172.31.255.255

192.168.0.0 - 192.168.255.255

You can obtain your IP address from the IANA, from an ISP, or assigned from a private network. If you
belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the
Internet addresses for your local networks. On the other hand, if you are part of a much larger organization,
you should consult your network administrator for the appropriate IP addresses.

NOTE: Regardless of your particular situation, do not create an arbitrary IP address;

always follow the guidelines above. For more information on address assignment,

please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466,

Guidelines for Management of IP Address Space.

3.1.4 RIP (Routing Information Protocol) Setup

RIP allows a router to exchange routing information with other routers. The RIP Direction field controls the
sending and receiving of RIP packets. When set to Both or Out Only, the Prestige broadcasts its routing
table periodically. When set to Both or In Only, it incorporates the RIP information that it receives; when
set to None, it does not send any RIP packets and ignores any RIP packets received.
The Version field controls the format and the broadcasting method of the RIP packets that the Prestige
sends (it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more
information. RIP-1 is probably adequate for most networks, unless you have an unusual network topology.
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses
subnet broadcasting while RIP-2M uses multicasting. Multicasting can reduce the load on non-router
machines since they generally do not listen to the RIP multicast address and so does not receive the RIP
packets. However, if one router uses multicasting, then all routers on your network must use multicasting,
also.
By default, RIP direction is set to Both and the Version set to RIP-1.

3-2 Internet Access

Prestige 100L IDSL Router

3.1.5 DHCP (Dynamic Host Configuration Protocol) Configuration

DHCP allows the individual clients (workstations) to obtain the TCP/IP configuration at start-up from a
server. Unless you are instructed by your ISP, leave the DHCP at the Server default value. You can
configure the Prestige as a DHCP server or disable it. When configured as a server, the Prestige provides the
TCP/IP configuration for the clients.

IP Pool Setup

The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64.
This configuration leaves 31 IP addresses (excluding the Prestige itself) in the lower range for other server
machines, e.g., server for mail, FTP, telnet, web, etc., that you may have.

DNS (Domain Name System) Server Address

DNS is for mapping a domain name to its corresponding IP address and vice versa, e.g., the IP address of
www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know
the IP address of a machine before you can access it.
There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to tell a
customer the DNS server addresses, usually in the form of an information sheet, when you sign up. If your
ISP does give you the DNS server addresses, enter them in the DNS Server fields in DHCP Setup. The
second is to leave this field blank, i.e., 0.0.0.0, – in this case the Prestige acts as a DNS proxy.

IP Subnet Mask

A subnet mask is a 32-bit quantity that, when logically ANDed with an IP address, yields the network
number. For instance, the subnet masks for Class A, B, and C without subnetting are 255.0.0.0, 255.255.0.0,
and 255.255.255.0, respectively. To create more network numbers, you shift some bits from the host ID to
the network ID. For instance, to partition a Class C network number 192.68.135.0 into two, you shift 1 bit
from the host ID to the network ID. Thus the new subnet mask is 255.255.255.128; the first subnet have a
network number of 192.68.135.0 with hosts 192.68.135.1 to 192.68.135.126 and the second subnet have a
network number of 192.68.135.128 with hosts 192.68.135.129 to 192.68.135.254. It is recommended that
you use the same subnet mask for all physical networks that share an IP network number. The following table
lists the additional subnet mask bits in dot decimal notations. To use the following table, write down the
original subnet mask and substitute the higher order “0”s with the dot decimal of the additional subnet bits.
For instance, to partition your Class C network 204.247.203.0 with subnet mask 255.255.255.0 into 16
subnets (4 bits), the new subnet mask becomes 255.255.255.240.

Single User Account feature. The default value is Yes.

IP Address

Please refer to the following section for a more detailed discussion on setting
the IP Address under a Single User Account.

3.4 Single User Account (SUA)

Typically, if there are multiple users on the LAN wanting to concurrently access the Internet, you have to
lease a block of legal, or globally unique, IP addresses from the ISP.
The Single User Account (SUA) feature allows you to have the same benefits as having multiple legal
addresses, but only pay for one IP address, thus saving significantly on the subscription fees. (Check with
your ISP before you enable this feature). SUA supports popular Internet applications such as MS traceroute,
CuSeeMe, IRC, RealAudio, VDOLive, Quake and PPTP with no extra configuration needed.
The IP address for the SUA can be either fixed or dynamically assigned by the ISP. In addition, you can
designate servers, e.g., a web server and a telnet server, on your local network and make them accessible to
the outside world. If you do not define any server, SUA offers the additional benefit of firewall protection. If
no server is defined, all incoming inquiries are filtered out by your Prestige, thus preventing intruders from
probing your network. Your Prestige accomplishes this address sharing by translating the internal LAN IP
addresses to a single address that is globally unique on the Internet. For more information on IP address
translation, refer to RFC 1631, The IP Network Address Translator (NAT).

3.4.1 Advantages of SUA

l SUA is an ideal, cost-effective solution for small offices to access the Internet or other remote TCP/IP

networks.

l SUA supports servers to be accessible to the outside world.
l SUA can provide firewall protection if you do not specify a server. All incoming inquiries are filtered

out by your Prestige.

l UDP and TCP packets can be routed. In addition, partial ICMP, including echo and traceroute, is also

supported.

3.4.2 Single User Account Configuration

The steps for configuring your Prestige for Single User Account are identical to the conventional Internet
access with the exception that you need to fill in two extra fields in Menu 4 – Internet Access Setup (please
refer to Figure 3-3). To enable the SUA feature in Menu 4, move the cursor to the Single User Account field
and select Yes (or No to disable SUA). Then follow the instructions on how to configure the SUA fields.

Press the [Enter] key at the message [Press ENTER to Confirm . . . ] to save your
configuration, or press the [Esc] key at any time to cancel.

If your ISP did not assign you a static IP address, enter [0.0.0.0]
here; otherwise, enter that IP address here.

3.5 Multiple Servers Behind the SUA

If you wish, you can make inside servers for different services, e.g., web or FTP, visible to the outside users,
even though SUA makes your whole internal network appear as a single machine to the outside world. A
service is identified by the port number, e.g., web service is on port 80 and FTP on port 21.
As an example (see the following figure), if you have a web server at 192.168.1.36 and an FTP server at

192.168.1.33, then you need to specify for port 80 (web) the server at IP address 192.168.1.36 and for port 21
(FTP) another at IP address 192.168.1.33.
Please note that a server can support more than one service, e.g., a server can provide both FTP and DNS
service, while another provides only web service. Also, since you need to specify the IP address of a server in
the Prestige, a server must have a fixed IP address and not be a DHCP client whose IP address potentially
changes each time it is powered on.
In addition to the servers for specific services, SUA supports a default server. A service request that does not
have a server explicitly designated for it is forwarded to the default server. If the default server is not defined,
the service request is simply discarded.

Chapter 4

Remote Node Setup

This chapter shows you how to configure a remote node.

A remote node is required for placing calls to a remote gateway. A remote node represents both the remote
gateway and the network behind it across an IDSL connection. Note that when you use Menu 4 to set up
Internet access, you are actually configuring a remote node.
Even though you can configure up to four remote nodes, the first active remote node is used to connect to
the remote LAN. It is good practice to keep only one active remote node for your Prestige.
In this chapter, we discuss the parameters that are protocol independent. The protocol dependent
configuration is covered in subsequent chapters. You are also shown how to configure Menu 11.1 Remote

Node Profile, Menu 11.2 – Remote Node PPP Options, Menu 11.3 – Remote Node Network Layer
Options and Menu 11.5 – Remote Node Filter.

Your Prestige supports two authentication protocols: PAP
(Password Authentication Protocol) and CHAP (Challenge
Handshake Authentication Protocol).

• PAP sends the user name and password in plain text.

• CHAP scrambles the password before it is sent over the wire.

Generally speaking, CHAP is more secure than PAP, however,
PAP is readily available on more platforms. The recommendation
is to use CHAP whenever possible. Turning off the authentication
is STRONGLY discouraged.
Options for this field are:

• CHAP/PAP – your Prestige tries CHAP when CHAP is
requested by the Remote Node or PAP when PAP is
requested by the Remote Node.

• CHAP – use CHAP only.

• PAP – use PAP only.

IP Static Route Setup

This chapter shows you how to configure static routes with your Prestige.

Static routes tell the Prestige routing information that it cannot learn automatically through other means.
This can arise in cases where RIP is disabled on the LAN or a remote network is beyond the one that is
directly connected to a remote node.
Each remote node specifies only the network to which the gateway is directly connected, and the Prestige
has no knowledge of the networks beyond. For instance, the Prestige knows about network (N2) in the
following diagram through remote node Router 1. However, the Prestige is unable to route a packet to
network (N3) because it does not know that there is a route through remote node Router 2. The static routes
are for you to tell the Prestige about the networks beyond the remote nodes.

Filter Configuration

This chapter shows you how to create and apply filter(s).

6.1 About Filtering

Your Prestige uses filters to decide whether to allow passage of a data packet and/or to make a call. There
are two types of filter applications: data filtering and call filtering. Filters are subdivided into device and
protocol filters, which are discussed later.
Data filtering screens the data to determine if the packet should be allowed to pass. Data filters are divided
into incoming and outgoing filters, depending on the direction of the packet relative to a port. Data filtering
can be applied on either the WAN side or the Ethernet side. Call filtering is used to determine if a packet
should be allowed to trigger a call. Outgoing packets must undergo data filtering before they encounter call
filtering as shown in the following figure.

For incoming packets, your Prestige applies data filters only. Packets are processed depending upon
whether a match is found. The following sections describe how to configure filter sets.

Filters 6-1

Prestige 100L IDSL Router

6.1.1 The Filter Structure of the Prestige

A filter set consists of one or more filter rules. Usually, you would group related rules, e.g., all the rules for
NetBIOS, into a single set and give it a descriptive name. The Prestige allows you to configure up to twelve
filter sets with six rules in each set, for a total of 72 filter rules in the system. You cannot mix device filter
rules and protocol filter rules within the same set. You can apply up to four filter sets to a particular port to
block multiple types of packets. With each filter set having up to six rules, you can have a maximum of 24
rules active for a single port.
Three sets of factory default filter rules have been configured in Menu 21 to prevent NetBIOS traffic from
triggering calls and to prevent incoming telnetting. A summary of their filter rules is shown in the figures
that follow.
The following diagram illustrates the logic flow when executing a filter rule.

6.2.4 Generic Filter Rule

This section shows you how to configure a generic filter rule. The purpose of generic rules is to allow you
to filter non-IP packets. For IP, it is generally easier to use the IP rules directly.
For generic rules, the Prestige treats a packet as a byte stream as opposed to an IP or IPX packet. You
specify the portion of the packet to check with the Offset (from 0) and the Length fields, both in bytes. The
Prestige applies the Mask (bit-wise ANDing) to the data portion before comparing the result against the
Value to determine a match. The Mask and Value are specified in hexadecimal numbers. Note that it takes
two hexadecimal digits to represent a byte, so if the length is 4, the value in either field takes 8 digits, e.g.,
FFFFFFFF.
To configure a generic rule, select Generic Filter Rule in the Filter Type field in the Menu 21.3.1 and press
the [Enter] key to open Generic Filter Rule, as shown below.

6.4 Applying a Filter and Factory Defaults

This section shows you where to apply the filter(s) after you designed it (them). Three sets of factory
default filter rules have been configured in Menu 21 to prevent NetBIOS traffic from triggering calls and to
prevent incoming telnetting.

6.4.1 Ethernet Traffic

You seldom need to filter Ethernet traffic; however, the filter sets may be useful to block certain packets,
reduce traffic and prevent security breaches. Go to Menu 3.1 (shown below) and enter the number(s) of the
filter set(s) that you want to apply as appropriate. You can choose up to four filter sets (from twelve) by
entering their numbers separated by commas, e.g., 3, 4, 6, 11. Input filter sets filter incoming traffic to the
Prestige and Output filter sets filter outgoing traffic from the Prestige. The factory default set,
NetBIOS_LAN, is inserted in protocol filters field under Input Filter Sets in Menu 3.1 to block NetBIOS
traffic to the Prestige from the LAN.

up to four filter sets by entering their numbers separated by commas. The factory default filter set,
NetBIOS_WAN, is inserted in the protocol filters field under Call Filter Sets in Menu 11.5 to block local
NetBIOS traffic from triggering calls to the ISP. Filter set three, Telnet_WAN, blocks telnet connections
from the WAN Port to help prevent security breaches. When you cannot connect using telnet service from

SNMP (Simple Network Management

Protocol)

This chapter takes you through SNMP Configuration Menu 22.

The SNMP is a protocol governing network management and the monitoring of network devices and their
functions. The Prestige 100L supports the utilization of SNMP to regulate the communication that occurs
between the manager station and the agent stations in a network. Basically, your Prestige, when connected
to the LAN, acts as an agent station. In this way, the manager station on your LAN can monitor your
Prestige as it would another station on the network. Keep in mind that SNMP is only available if TCP/IP is
configured.

Configuring Your Prestige For SNMP Support

The following steps describe a simple setup procedure for configuring SNMP management.

System Security

This chapter talks you through System Password Menu 23.

The Prestige 100L incorporates a number of security measures to prevent unauthorized access to your
network. For example, your Prestige supports both PAP (Password Authentication Protocol) and CHAP
(Challenge Handshake Authentication Protocol) in authenticating a Remote Node.
In addition, your Prestige also implements a user password to get into the SMT screen. You have three
attempts to enter the correct system password. If all three attempts fail, the SMT logs out. In addition, your
Prestige only supports one user in the SMT at one time.

Telnet Configuration and Capabilities

This chapter covers the Telnet Configuration and Capabilities of the Prestige.

9.1 About Telnet Configuration

Before the Prestige is properly setup for TCP/IP, the only option for configuring it is through the console
port. Once your Prestige is configured, you can use telnet to configure it remotely as shown in the following
figure.

Figure 9-1 Telnet Configuration on a TCP/IP Network

9.2 Telnet Capabilities

9.2.1 Single Administrator

To prevent confusion and discrepancy on the configuration, your Prestige only allows one administrator to
log in at any time. Your Prestige also gives priority to the console port over telnet. If you have already
connected to your Prestige via telnet, you are logged out if another user logs in to the Prestige via the
console port.

9.2.2 System Timeout

There is a system timeout of 5 minutes (300 seconds) for either the console port or telnet. Your Prestige
automatically logs you out if you do nothing in this timeout period, except when it is continuously updating
the status in Menu 24.1.

Transferring Files

This chapter tells you how to back up and restore your configuration file as well as upload new

firmware and a new configuration file.

11.1 Filename Conventions

The configuration file (sometimes called the romfile or romfile-0) contains the settings in the menus such as
password, DHCP Setup defaults, TCP/IP Setup defaults, etc. The external (i.e., not on the Prestige)
configuration filename is usually the router model name with a *.rom extension, e.g., P100L.rom. The RAS
firmware file is the file that contains the ZyXEL Network Operating System firmware and the external
firmware file is usually called the router model name with a *.bin extension, e.g., P100L.bin. Rename the
configuration filename to “rom-0” and the firmware filename to “ras” when transferring files to the Prestige
(i.e., the internal filenames on the Prestige). Renaming the files is not necessary when you transfer files to
the Prestige using the X-Modem protocol.
The following table is a summary. Please note that the internal filename refers to the filename on the
Prestige and the external filename refers to the filename not on the Prestige, i.e., on your workstation, local
network or ftp site and so the name (but not the extension) varies. The AT command is the command you
enter after you press “Y” when prompted in the SMT menu to go into debug mode. After uploading new
firmware see the ZyNOS F/W Version field in Menu 24.2.1 to check if you have uploaded the correct
firmware version.

11.2 Backup Configuration

Option 5 from Menu 24 – System Maintenance allows you to backup the current Prestige configuration to
your workstation. Backup is highly recommended once your Prestige is functioning properly. TFTP is the
preferred method for backing up your current workstation configuration to your computer since TFTP is
faster. You can also perform backup and restore using menu 24 through the console port. Any serial
communications program should work fine; however, you must use XMODEM protocol to perform the
download/upload and you do not have to rename the files (see Section 11.1).
Please note that terms “download” and “upload” are relative to the workstation. Download means to
transfer from another machine to the your workstation, while upload means from your workstation to
another machine.

Menu 24.6 – System Maintenance – Restore Configuration allows you to restore the configuration via the console port. Note that this function erases the current configuration before restoring to the previous back up configuration; please do not attempt to restore unless you have a backup configuration stored on disk. TFTP is the preferred methods for restoring your current workstation configuration to your Prestige since TFTP is faster. Please note that the system reboots automatically after the file transfer is complete.

11.5 TFTP File Transfer

In addition to the direct console port connection, the Prestige supports the up/downloading of the firmware
and the configuration file using TFTP (Trivial File Transfer Protocol) over LAN. Although TFTP should
work over WAN as well, it is not recommended.
To use TFTP, your workstation must have both telnet and TFTP clients. To transfer the firmware and the
configuration file, follow the next procedure:

Step 1. Use telnet from your workstation to connect to the Prestige and log in. Because TFTP does not

have any security checks, the Prestige records the IP address of the telnet client and accepts
TFTP requests only from this address.

Step 2. Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System

Maintenance.

Step 3. Enter command sys stdio 0 to disable the SMT timeout, so the TFTP transfer is not

interrupted. Enter command sys stdio 5 to restore the five-minute SMT timeout (default)
when the file transfer is complete.

Step 4. Launch the TFTP client on your workstation and connect to the Prestige. Set the transfer mode

to binary before starting data transfer.

Step 5. Use the TFTP client (see the example below) to transfer files between the Prestige and the

workstation. The file name for the firmware is ras and for the configuration file, it is rom-0
(rom-zero, not capital o).

Transferring Files 11-5

Prestige 100L IDSL Router

NOTE: If you upload the firmware to the Prestige, it reboots automatically when the

file transfer is completed (the SYS LED flashes).

Note that the telnet connection must be active and the SMT in CI mode before and during the TFTP
transfer. For details on TFTP commands (see following example), please consult the documentation of your
TFTP client program. For UNIX, use get to transfer from the Prestige to the workstation, put the other
way around, and binary to set binary transfer mode.

11.5.1 Using the FTP Command From the DOS Prompt

Step 1. Launch the FTP client on your workstation.
Step 2. Type open and the IP address of your Prestige.

Step 3. You may press the [Enter] key when prompted for a username.
Step 4. Type root and your SMT password as requested. The default is 1234.

Step 5. Type bin to set transfer mode to binary.
Step 6. Use put to transfer files from the workstation to the Prestige, e.g., put p100l.bin ras

transfers the firmware on your computer (p100l.bin) to the Prestige and renames it “ras”.
Similarly put p100l.rom rom transfers the configuration file on your computer (p100l.rom) to
the Prestige and renames it “rom”.

Step 7. Type quit to exit the ftp prompt.
