About the RAS 1500

Overview

The RAS 1500 is a stackable unit that provides terminal server and remote
access services, via analog and ISDN BRI connections in a multi-protocol
networking environment.

Consisting of a base router module (RM), port expansion module (PEM),
and user-installable Input/Output (I/O) modules, RAS 1500 integrates
multiprotocol remote access server and WAN router technology with
high-performance 56 kbps (V.90) and/or ISDN modems.

The RAS 1500 is a powerful data communications platform that can
support a broad variety of remote access applications.

The basic configuration of a RAS 1500 stack consists of one RM and two
PEMs and supports up to 24 channels (up to a total of 12 BRI lines, 24
analog lines, or any combination up to 24 channels).

In a full RAS 1500 stack, each PEM is connected to the RM using 3Com’s
StackNet, a high speed (up to 200 Mbps), low cost technology.

Figure 1-1

One RM and two PEMs in a Stack without a StackNet Connection

Applications

Overview 1-3

The RAS 1500 is a multi-protocol, dial-up router and terminal server
commonly described as a remote access server. The RAS 1500 performs
five basic applications:

■ IP Terminal Service

■ Network Dial-in Access

■ Dial-out Access (NCSI or telnet)

■ LAN-to-LAN Routing

■ Bridging

For more information about configuring these basic applications, see the
SuperStack II Remote Access System 1500 Resource CD-ROM.

Application of the RAS 1500 within the IP Network

IP Terminal Service

RAS 1500 provides network access for dumb terminals or computers that
emulate dumb terminals. The ASCII data stream to and from these
remote terminals is converted into a networking protocol (telnet, Rlogin,
or ClearTCP) and a session is established with a host to provide an IP
terminal service connection on the RAS 1500’s local network.

NTRODUCING THE SUPERSTACK

The RAS 1500 offers extensive access security, dialback, and easy
configuration for terminal service connections.

Network Dial-in Access

RAS 1500 provides dial-in network access for remote users. Remote IP,
IPX and Appletalk network users can dial in and connect to the local
network as if they were local nodes.

Packets transmitted over the dial-in connection are encapsulated using
the following protocols:

■

PPP (Point-to-Point Protocol)

■

SLIP (Serial Line IP Protocol)

■

FCP (3Com’s Fast Connect Protocol)

Dial-out Access

You can access RAS 1500 ports with network computers and
workstations to provide users with NCSI and Telnet dial-out services. This
allows network users to connect to Bulletin Board Systems (BBSs) or
information services such as CompuServe, or access the Internet over a
dial-up connection.

II R

EMOTE ACCESS SYSTEM

1500

IP or IPX LAN users require a NCSI-compatible communications
application to access RAS 1500 modems.

LAN-to-LAN Routing and Bridging

RAS 1500 performs dial-up routing over a PPP connection between
facilities. Routing occurs when one device dials up another device and
logs in as a user.

There are several types of LAN-to-LAN connections:

■

Manual

■

On demand

■

Timed

■

Continuous

RAS 1500 supports many routing and protocol configurations. It is
capable of establishing additional connections to increase bandwidth
automatically when network traffic increases.

Overview 1-5

Security Options

Configuration

Options

RAS 1500 supports the following security options:

■ IP packet filtering in both the inbound and the outbound directions of

ports, users, and dial-out locations.

■ RADIUS

■ NOS-based authentication (Windows NT 4.0, Novell NetWare)

■ Dial-back, fixed and roaming

■ PAP and CHAP

■ Local password authentication

The RAS 1500 supports the following configuration options:

■ TRAM

■ Command Line Interface (CLI)

TRAM

TRAM allows you to configure your RAS 1500 using a GUI interface, if
you are using Windows 95 or Windows NT 4.0.

Command Line Interface

The RAS 1500’s CLI includes an assortment of utilities for troubleshooting
connections including:

Universal Connect

ISDN Configuration

■ The ability to manually dial a location to test connectivity

■ The ability to use telnet, Rlogin or ClearTCP to establish a session with

another host.

■ UNIX-like troubleshooting commands including ping to debug IP

connections.

Universal Connect allows ISDN I/O module users to access information at
analog speeds up to 56 Kbps and at digital speeds up to 128 Kbps from
the same equipment and port.

The RAS 1500 supports Basic Rate Interface (BRI) ISDN with either the
U-Interface (for North America) or the S/T-Interface (for other countries).
Contact your ISDN provider for information about ISDN in your area or
call 1-800-877-ISDN (USA only).

RAS 1500 modules can be mounted in any order, but for ease of
management, we recommend you install RAS 1500 unit on the bottom
of the stack or rack.

Rack Installation

Guidelines

Follow these guidelines when you install RAS 1500 in a rack.

■

Operating Ambient Temperature. If the RAS 1500 is installed in a

closed or multi-module rack assembly, the operating ambient

temperature of the rack environment may be greater than room

ambient temperature. We therefore recommend that you install the

equipment in an environment compatible with the RAS 1500’s

maximum rated ambient temperature. Refer to Appendix A for

detailed technical specifications.

■

Air Flow. Install the RAS 1500 so that the rack has enough air flow for

safe operation.

If the RAS 1500 fails while in a rack, you might have to allow more
spacing between the other equipment in the rack to provide more air
flow.

■

Mechanical Loading. To avoid a hazardous condition, mount the

equipment in the rack evenly and place the rack on a stable surface.

■

Circuit Overloading. Make sure the RAS 1500 is properly connected to

the power supply circuit. This circuit should include overcurrent

protection and proper power supply wiring.

■

Grounding. Maintain reliable grounding of the rack-mounted

RAS 1500. Do not connect the RAS 1500 to a power supply

connection other than the branch circuit.

Grounding the RM and the PEM

Stack installation of an RM and at least one PEM require proper
grounding. Grounding straps are enclosed in the accessories kit. Install
them as follows:

Remove one cover screw on RM and PEM.

1

Install a ground strap between the RM cover and the PEM cover and

Accessing the CLI

Remotely

To access the CLI remotely, you need to do the following:

■ Setting up a manage user

■ Access the CLI with TELNET

Setting up a Manage User

Manage users are the only type of users who can configure the
RAS 1500. The default login service is Telnet; the default dial-in service is
PPP.

Use the following steps to set up a manage user:

Add a user. For example, user “michael” with password “benji”.

1

At the CLI prompt, type:

add user michael password benji type manage

Press Enter.

The “manage” portion of the command gives the user configuration
rights in the CLI.

Passwords are optional. You may add a null password with the keyword
password and string: “”

Save the settings:

2

save all

Then press Enter.

Accessing the CLI with TELNET

This procedure accesses the RAS 1500 through a login session. For
information about accessing the RAS 1500 through a dial-in session, refer
to the RAS 1500 System Management Guide on the RAS 1500 Resource
CD-ROM.

You can configure the RAS 1500 CLI in two ways:

■

Using the CLI Quick Setup (recommended)

■

Using CLI commands only

RAS 1500’s automated Quick Setup program provides initial
configuration through the CLI. It starts automatically after the boot
process of an unconfigured device (or when you type

delete config

the CLI prompt).

3Com recommends using the CLI Quick Setup to configure the RAS 1500
and access the graphic user interface. The Quick Setup will let you set up
simple configuration for your whole system or different portions of the
system. Use the steps in the following section to perform basic CLI
configuration.

To configure enough to use the GUI based system, through the CLI Quick
Setup, follow these steps:

Enter system identification information. The following prompts will

1

appear on your screen.

>>> Enter the name of your system []:
>>> Who is the system contact person []:
>>> Where is this system located []?

at

Add Quick Setup management information. The GUI-based management

2

system uses SNMP to communicate with the RAS 1500. The following CLI
prompt will request an IP address for your management station.

>>> What is the address of the management station [0.0.0.0]?

Setting the management station address to 0.0.0.0 allows all stations to
manage the RAS 1500. Setting a specific address limits management to a
single computer and provides a level of security.

Basic CLI Configuration 4-5

Add the following network administration information:

3

Configure the IP address.

a

>>> Enter the network name of your IP network [ip]:
>>> Enter the IP address for the RAS 1500 []:

Specify an IP mask. The default mask appears in brackets in the CLI

b

prompt.

>>> What should the mask be set to [C]?

Configure the default gateway. The default gateway gives the address

c

of a router that the RAS 1500 will forward packets to when it has no
other route to their destination.

The IP address for the default gateway cannot be the same address as the
IP address for the RAS 1500 nor can it be a broadcast address for its IP
address class.

>>> Enter the IP address of the default gateway []?

Enter the metric or “hop count.” The metric or hop count tells the

d

RAS 1500 how far the default router is from the unit.

>>> What metric should be applied to the default gateway [1]?

Save your changes by typing

4

save all.

At the end of the Quick Setup program you can review and change your
settings, if necessary. You can continue advanced configuration with the
CLI, or with TRAM.

Configuring ISDN

Once you have peformed the basic RAS 1500 configuration, configure
RAS 1500 for ISDN. See “Using the I-Team” in

Assistance

, for more information about ordering ISDN service.

Appendix A, Configuration

See “Accessing the CLI Locally”, earlier in this chapter, to connect to the
Console Port.

Use the following steps to configure RAS 1500 for ISDN:

If the switch type = NI - 1 (U.S. only), you need to specify Service Profile
Identifiers (SPIDs). If a different switch type is being configured, proceed
to Step 2.

Set up the Service Profile Identifiers (SPIDs):

1

set imod int rm0/slot:1/mod:1 at at*s1=[10 digit SPID]
set imod int rm0/slot:1/mod:1 at at*s2=[10 digit SPID]

You can set the SPIDs on modem channel one (rm0/slot:1/mod:1) or
modem channel two (rm0/slot:1/mod:2); RAS 1500 applies the settings to
both channels.

Set up the Directory Numbers (DNs) if applicable:

2

set imod int rm0/slot:1/mod:1 at at*p1=[7 digit DN]
set imod int rm0/slot:1/mod:1 at at*p2=[7 digit DN]

set imod int rm0/slot:1/mod:1 at at*v2=5
set imod int rm0/slot:1/mod:2 at at*v2=5

You need to force a connection type for both channels (rm0/slot:1/mod:1
and rm0/slot:1/mod:2).

Save your changes:

5

set imod int rm0/slot:1/mod:1 at at&wz!

The RAS 1500 stack does not immediately recognize the removal or
substitution of PEM units.

To remove and substitute another PEM module to an existing setup, issue
the

reboot

command at the CLI prompt.

After the reboot process occurs, RM automatically recognizes each PEM
attached to it.
