Chapter 1
Introduction to Nokia M11

Nokia M11 is an ADSL (Asymmetric Digital Subscriber Line) modem
which enables high-speed Internet access and LAN (Local Area
Network) interconnection. It increases the capacity of the already
installed telephone lines used traditionally for telephone services.
M11 enables high-speed connections for residential users, small
offices and telecommuters.

remote IP network via a Digital Subscriber Line Access Multiplexer
(DSLAM) and an ATM access network. M11 can also act as a bridge
between the Ethernet LAN and ADSL/ATM network interfaces. M11
is compatible with Nokia D DSLAM.

The ADSL transmission is based on a DMT (Discrete multitone) line
code and it provides speeds up to 8 Mbit/s downstream (from the
network) and 1 Mbit/s upstream (to the network). M11 can adjust its
speed to the line conditions in steps of 32 kbit/s, maximising the data
throughput over the given distance. Nokia M1 1 is compatible with the
existing and emerging ADSL standards: ANSI T1.413 Issue 2 (ANSI
ADSL), ITU-T G.992.1 (ITU-T ADSL), ITU-T G.992.2 (ITU-T
ADSL Lite), and ITU-T G.996.1 (Handshake).

M11 provides optimised access to high-speed data services. It can be
used to connect telecommuters to the corporate network or netsurfers
to the Internet Service Provider’s (ISP) network, for example.

As a default, M11 supports plug-and-play operation for Internet access
applications. The ADSL connection, data connection and Internet
network addresses are set up automatically.

M11 has an integrated W eb server which enables configuring the most
frequently used parameters with an ordinary Web browser. M11 can
also be managed through a command line interface via telnet protocol
or via local console interface.

An external POTS (Plain Old Telephone System) filter enables the
simultaneous use of the conventional telephone service and the ADSL
data services.

Chapter 2
Applications and features

This chapter introduces the most common applications, features and
management method options of M1 1.

2.1 Applications

M11 has three main applications:

D Internet access
D Remote work
D LAN interconnection

In these application examples M11 can act as a router , bridge or NAPT
router . The selected mode for every single application depends on the
access and service provider network architectures. Some basic
application examples are described in this chapter. See Chapter 6 for
more information on routing, bridging and Network Address Port
Translation.

2.1.1 Internet access using M11 as a NAPT router

M11 can connect your PC via your operator’s Digital Subscriber Line
Access Multiplexer (DSLAM) and ATM network to an Internet
Service Provider (ISP). If you are connected to a single ISP, the
network addresses (IP addresses) in your home can be part of the ISP’s
IP address range. However, in many cases it is more practical that the
home network is an independent network utilising private IP addresses
which are not visible to outside and that M11 has only one external IP
address received from the ISP. The external Internet services are

accessed through this single IP address. This mode of operation is
called the Network Port Address Translation (NAPT).

The benefits of NAPT are the minimum coupling of the ISP and the
home network, the saving of public IP addresses, and in-built simple
firewall functionality .

2.1.2 Remote work

In a typical remote work application M11 is used as an IP router to
provide access to corporate Intranet services. Using routing between
the home and the corporate networks prevents unnecessary broadcast
traffic and non-IP protocol traf fic from loading the access connection
Still, it provides sufficient transparency for Intranet applications. The
M11 routing table can be static or it can be updated dynamically using
RIP version 1 and RIP version 2 routing protocols.

2.1.3 LAN interconnection using M11 as a bridge

LAN interconnection between corporate headquarters and its remote
office is another typical M1 1 application. In the LAN interconnection
application, M11 is typically used as an Ethernet bridge which relays
all non-local Ethernet traffic between the corporate headquarters and
remote sites through the ATM core network.

The benefit of bridging in this application example is the transparency
for all network protocols in a multiprotocol data communications
corporate network.

2.2 Features

M11 can operate as an OSI layer 3 Internet Protocol (IP) router
between the Ethernet interface and the virtual channels of ADSL/A TM
interface. M11 supports both dynamic and static routing.

It can also operate as a self-learning bridge supporting up to 256 MAC
addresses.

M11 supports IGMP (Internet Group Management Protocol) proxy
function for IP multicast applications.

Routing

Routing is based on routing entries in a routing table. Static routes are
added via the management interface and dynamic routing is done using
RIP and RIPv2. Routing is done between the Ethernet 10Base-T
interface and the virtual channel connection (VCC) of the A TM/ADSL
interface. Optionally, the routing between the VCCs can be disabled.
M11 supports up to 8 simultaneous VCCs.

Bridging

Bridging is supported to provide full protocol transparency . Bridging
can be used simultaneously with IP routing. M11 works as a
self-learning bridge supporting up to 256 MAC addresses. Bridging is
done between the Ethernet 10Base-T interface and each ATM VCC
interface. Optionally , the bridging between the VCCs can be disabled.
M11 supports up to 8 simultaneous VCCs.

Network Address Port Translation

M11 supports Network Address Port Translation (NAPT) for TCP/IP
and UDP/IP protocols. When NAPT is used, a single IP address is
allocated to a VCC which leads to the public IP network. The Ethernet
subnet has private IP addressing and is not visible to the VCC. NAPT
translates the IP source address and source port number dynamically to
the VCC IP address and port number. Similarly, packets coming from
the VCC are mapped back to the original destination addresses. NAPT
allows up to 253 hosts to share a single VCC IP address to the public
network. The Network Address Port Translation principle is presented
in Figure 2-4.

NAPT may restrict the operation of some IP applications. NAPT also
operates as a simple IP firewall because translation is only allowed
when the first packet is transmitted from the LAN. This means that the
NAPT table entry is created only when a packet is sent from the home
network to the Internet. W ith pinhole capability , the user can add static
entries to the NAPT table allowing the translation always in both
directions. This capability is used to add servers (HTTP, NNTP, and
FTP), which are visible to the public IP network via the VCC, on the
LAN subnet.

Dynamic Host Configuration

M11 can act as a Dynamic Host Configuration Protocol (DHCP)
server for the PCs on the end-user home network. In this mode, M11
can assign up to 253 IP addresses to the PCs on the home network. M11
can also act as a DHCP relay agent and relay the DHCP requests to an
external DHCP server.

ATM and ADSL

M11 supports up to 8 simultaneous VCCs and supports UBR
(Unspecified bit rate) traffic shaping on all VCCs. The maximum
transmit rate on each VCC is the ADSL upstream capacity. If more
than one VCC is transmitting simultaneously, the ADSL upstream
capacity is temporarily shared between these VCCs. When one VCC is
idle, the bandwidth is used by another VCC. M11 also supports limited
CBR on upstream (see Transmit priority selection in this chapter).

The ADSL transmission is based on the DMT line code. M11 provides
a DMT line rate up to 8 Mbit/s downstream and up to 1 Mbit/s
upstream. The DMT transceiver is rate adaptive and capable of
providing faster rates over short distances or slower rates over long
distances. The transceiver adapts itself to the line conditions. M11
supports also ADSL Lite. In the ADSL Lite mode, the maximum line
rates are 1536 kbit/s downstream and 512 kbit/s upstream.

The A TM over ADSL transmission is based on ITU-T G.992.1. ADSL
Lite is based on ITU-T G.992.2.

Rate adaptation is done in steps of 32 kbit/s. The ADSL interface of
M11 functions completely automatically and all configuration related
to the ADSL connection is done at the access multiplexer in the
operator’s premises. The network operator can set the data rates as a
part of the network management functionality provided by Nokia D
DSLAM.

Payload encapsulations

Both routed and bridged protocols are encapsulated in the A TM link by
using either RFC 1483 LLC/SNAP encapsulation or VC multiplexing.
M11 also supports PPP over AAL5 encapsulation, in which both
bridged and routed protocols are first encapsulated in PPP (RFC 1661).
PPP is then encapsulated in ATM according to the IETF PPP over
AAL5 using RFC 2364 VC multiplexing or LLC/NLPID
encapsulation.

See Chapter 6 for more information on the payload encapsulations.

T ransmit priority selection

If you are using more than one upstream connections, you can set
priorities to these connections. You can also set the maximum transmit
rate to the connection. The following example explains the transmit
priority selection:

Connection Priority Maximum transmit

rate

VCC1 HIGH 400 kbit/s
VCC2 LOW 0 (no limit)

Table 2-1 Transmit priority selection example settings

The settings shown in T able 2-1 affect the connections in the following
way:

D When VCC1 is not transmitting, VCC2 can use the whole

bandwidth.

D When VCC2 is not transmitting, VCC1 gets only 400 kbit/s even if

there was more bandwidth available on the upstream link.

D When VCC1 starts transmitting, it gets 400 kbit/s bandwidth and

VCC2 gets the rest of the available bandwidth.

D If the upstream bandwidth is 400 kbit/s and VCC1 uses 400 kbit/s,

VCC2 can not transmit anything until VCC1 starts to transmit less
than 400 kbit/s.

IGMP proxy function

M11 can be used as an IGMP proxy which means that M11 can send
IGMP queries and have IP hosts report their IP multicast host group
memberships. See Chapter 6 for more information about IP multicast.

Management

There are four management methods in M1 1:

D Command line interface (CLI) through console serial port
D CLI via telnet
D SNMP
D Web browser management

The CLI allows complete configuration of the unit; the Web browser
management allows the configuration of the most frequently used
configuration parameters. SNMP can be used to read some equipment
identity information and to provide traps for authentication failures.

2.2.1 Dedicated management channel

The operator or Internet Service Provider can establish a dedicated
management channel to M1 1. This channel provides access to the M11
management (with telnet or W eb browser) and it can be used to upload
a new software to M11. When the management channel is in use it
prevents data traffic between the management channel and the
Ethernet as well as the traffic between the management channel and
other active ATM channels. Figure 2-5 shows the principle of the
dedicated management channel.

In Figure 2-5 VCC1 is used for customers data transmission.
Administration through this channel has been disabled. The operator
or the service provider uses the VCC2 for management purposes only .

Installing M11

This chapter presents step-by-step installation example procedures for
three different application examples of Nokia M11:

D Internet access (NAPT router)
D Remote work (basic router)
D LAN interconnection (basic bridge)

These installation procedures are examples to guide you through some
of the typical use cases.

In the installation examples, we assume that you have a new M11 with
a factory default configuration. The complete default configuration is
presented in the end of this chapter. The default settings are, briefly:

D Single ADSL/ATM channel (VPI = 0, VCI = 100)
D PPP over ATM/AAL5 encapsulation
D M11 retrieves IP address configuration from IP network using

PPP-IPCP negotiation

D Network Address Port Translation activated
D Private IP addresses in use in LAN
D DHCP server for LAN interface activated

Before starting the installation, unpack the unit and check that it is
physically undamaged.

The Internet access application requires that your PC uses Dynamic
Host Configuration Protocol (DHCP) to get its network address (IP
address) from your Nokia M11.

The installation procedure depends on whether you want to use data
services only or data and simultaneous telephone services. If you want
data services only, start from Step 1a. If you want both data and
telephone services, start from Step 1b .

M11 has an optional three-level password (user, user-admin, and
admin), which also affects the installation procedure. By default, the
password is disabled but it can be enabled through the command line
interface (see Chapter 5 Management). Steps 4b and 5b describe the
actions when password is enabled.

Step 1a: Connect cables (data services only)

Connect the following cables:

D Connect the mains power cord first to Nokia M11 and then to a

power outlet.

D Connect the Ethernet cross cable to the Nokia M11 ETH connector

and the other end to your PC’s Ethernet port.

D Connect the ADSL cable to the telephone socket.
D Go to Step 2.

Step 1b: Connect cables (data and telephone services)

If you want to use your telephone line for both the high-speed ADSL
service and normal telephone service, you must install a POTS filter .
You can use Nokia POTS filter T66130 or T66150. See separate
installation instructions for POTS filters.

Connect the following cables:

D Connect the mains power cord first to Nokia M11 and then to a

power outlet.

D Connect the Ethernet cross cable to the Nokia M11 ETH connector

and the other end to your PC’s Ethernet port.

D Connect the ADSL cable and the telephone according to the

separate POTS filter installation instructions.

D Go to Step 2.

Step 2: Switch on M1 1

The green STA indicator and red DSL indicator light up. After a while
the DSL light starts blinking, indicating that the connection is being

established. Green DSL light indicates that the unit has a connection to
the central office.

Step 3: Switch on PC

The LAN/LNK indicator lights up in the Nokia M11 front panel. Note
that you must activate the DHCP functionality in your PC to make it
retrieve an IP address from M11.

Step 4a: Connect to M11 with a Web browser (M11 password
disabled)

Start the W eb browser in your PC, write the IP address (192.168.1.254)
or the default name (M11) of the M11 to the HTTP address field and
press Enter. The M11 QuickConfig page is displayed. Note that the
QuickConfig page is displayed first only when M11 has its factory
default settings active. If M1 1 has been previously configured, the first
page to appear is the M11 home page. Go to Step 5a.

Step 3: Configure M11

In configurations given here, we assume that the unit uses its default
configurations and the changes are done on top of the default
configuration of the M11 version T66220.01.

The Nokia M11 command line interface includes a step mode to
automate the process of entering configuration settings. When you use
the Config step mode, the CLI prompts you for all required and
optional information. You can enter the configuration values
appropriate for your site without having to enter complete CLI
commands.

To enter the Config step, mode type

set from the top node of the

Config hierarchy. See Chapter 5 section Stepping through M11
configuration for more information on the step mode.

When you are in step mode, the CLI prompts you to enter the required
and optional settings. If a setting has a default value or a current
setting, the command line interface displays the default value for the
command in parentheses. If a command has a limited number of
acceptable values, those values are presented in brackets, with each
value separated by a vertical line. For example, the following CLI step
command indicates that the default value is off and that valid entries
are limited to on and off.

option (off) [on|off]: on <Enter>

You can accept the default value for a field by pressing the ENTER key.
To use a different value, type it in and press ENTER.

In the following example the values changed by the user are in bold
type. The default values have been accepted by pressing ENTER.

The following changes were made in the above basic router example:

D Ether-llc encapsulation was selected for ATM channel 1. This

encapsulation is used by your company’s main office bridge.
Alternatively, ether-vcmux encapsulation could be used. See
Chapter 6 for more information on the payload encapsulations.

D IP functionality, default gateway and interwan routing were

disabled in the Ethernet. Note, that you have to go through the IP
option twice: first to disable Ethernet and gateway options and
then to disable the IP option.

D DHCP option was disabled.
D Bridge was enabled.

Warnings related to 0.0.0.0 settings of DNS servers are irrelevant in
this configuration because the M11 is now a transparent bridge.
Messages given as Warnings are not fatal. If an actual error message
occurs the configuration has not been validated successfully and M11
does not save the configuration.

Step 4: Connect your M1 1 to the network

Connect the ADSL cable between the telephone socket and the LINE
connector of the M11. Then connect the ETH connector of the M11 to
your office hub with a direct cable. The green LAN LNK indicator
lights up when you connect the Ethernet cable. After a while the DSL
indicator starts blinking, indicating that the connection is being
established. The green DSL light indicates that the unit has a
connection to the central office.

Step 5: Check that the connection works

Establish a connection to the office server to check that the connection
works.

4.4 Default settings

The table 4-1 indicates the default settings for Nokia M11. By default,
Nokia M11 works as a plug and play unit in the Internet access
application. In the table, the terms “Node” and “Subnode” refer to

4.5 Troubleshooting

If the data transmission does not work, you can check the following
things:

Is the ADSL connection to the remote network working?

The front panel DSL indicator should be green if the ADSL link is
functioning. You can also view the ADSL link status by giving the

show dsl command line interface command. In case the ADSL link is

not functioning, check that the cables connecting the unit to the
telephone line/splitter are properly attached and then turn on the M11
again. If the ADSL link still does not work, contact your service
provider.

Is the Ethernet connection working?

The front panel LAN LNK indicator is green if the Ethernet cable is
properly attached. If not, ensure that the cables are properly connected.
Ensure also that you are using a right kind of Ethernet cable. If you
connect your M11 directly to a PC, you should use a cross-connect
cable. If you connect your M11 to a hub, you should use a direct cable.

Is the ATM connection working?

You can check if the ATM connection is working by giving the

show

atm CLI command. The ADSL connection must be working before the

Installing M11

A TM connection can be established. If the ADSL connection is OK but
the ATM connection is not, contact your service provider.

Is the PPP connection working?

If you are using PPP to connect to your service provider, you can also
check that your PPP connection is working. Y ou can do this by giving
the

show ppp CLI command. If the ADSL link and ATM link are

working but the PPP link is not, you should first check that the user
name and password you are using on the PPP link are correct. Y ou can
also try to restart the M11 (power -off and power-on) and check if the
connection is established. If these do not work, contact your service
provider for help.

Chapter 5
Management

M11 can be managed with a Web browser or command line interface
(CLI). The Web configuration pages of M11 can be accessed through
the Ethernet port or through the ADSL/A TM channels of M11. In order
to access the Web management feature, the IP functionality must be
activated and an IP address must be given to the corresponding
interface.

The command line interface (CLI) can be accessed through the console
port on the M11 front panel. The console interface is an asynchronous
V .24/V.28 character-based interface with 9600 bit/s, 8 bits, no parity , 1
stop bit and no flow control. A special cable for connecting PC’s serial
port to this interface is available from Nokia, product code E64320.01.
The CLI contains an in-built step procedure which helps you to
configure your M11 through the CLI. This procedure is presented in
section Stepping through M11 configuration in this chapter.

The command line interface can also be accessed through the Ethernet
port of M1 1 or through the ADSL/ATM channels of M11 on top of the
telnet protocol. In order to use the CLI through telnet, the IP
functionality must be activated and an IP address must be given to the
corresponding interface.

5.1 Browser management

You can use your PC’s Web browser software to access the Web
configuration pages in M1 1. To access the W eb pages you must know
the IP address of your M11 or , alternatively , the “name” that your M11
recognises.

Filling in router settings

1. Enter the name of your M11 in the System Name field.
Each M11 is assigned a name as a part of its factory initialisation.

The default name is M11. A system name can be 1-64 characters
long and cannot contain any special characters. If you want to use a
space character in the system name, you must use quotes, for
example “Nokia M1 1”. The name can be later used to access the
M11 through a telnet connection or a Web page from the Ethernet
interface.

2. Enter the IP address of your M11.
Local address is the IP address of your M11’s Ethernet interface.

3. Enter the subnet mask.
Net mask is used to identify the network portion of an IP address.

The net mask specifies which bits of the 32-bit binary IP address
represent the network information. Most sites should use

255.255.255.0 for their net mask.

4. Enter the broadcast address.
The Br oadcast addr ess is used to send messages to all computers

on your network. Most sites should use xxx.yyy.zzz.255 as their
broadcast address, where xxx.yyy .zzz is the network portion of the
IP address.

5. Enable/disable management through the Ethernet port (Admin
Restrictions).

Y ou can disable management through the Ethernet port by clicking
Admin-Disabled. You must have admin rights to set admin
restrictions.

Note

If you disable management through the Ethernet port and restart M11,
you can no longer manage M11 with your local telnet or W eb browser.

6. Enter RIP settings for the Ethernet interface.
Rip-send and Rip-receive radio buttons are used to enable

dynamic routing using Routing Information Protocol (RIP). RIP
and RIP version 2 can be used. RIP-send with V1-compat option
enables the sending of RIPv2 packets using broadcast.
RIP-receive with V1-compat option accepts both RIPv1 and
RIPv2 packets.

7. Enable/disable routing between ATM VCCs (Routing Policy).
IP forwarding and dynamic route distribution between A TM VCC

routing can be switched off when multiple VCCs are used.

8. Enable/disable default gateway .
The default gateway is the host to which your M11 will send a

packet when it does not know how to reach the packet’s
destination host.

9. Select the default gateway port from the Interface list.
The default gateway port can be one of the active PPP channels or a

specified IP address defined in Default Address field (see step

10.).

10. Set an IP address (Default Address) for your default gateway if you
selected “ip-address“ in step 9.

11. Enter domain name server settings.
A domain name server is a network computer responsible for

matching host names to numeric IP addresses so that network
traffic can be routed correctly. These fields are set if DNS
addresses are not allocated dynamically. Consult your service
provider for further assistance.

Domain names identify organisations on the Internet. The domain
name is usually the domain name of your company or your ISP.

If a secondary name server address is configured, M11 relays the
name service request to that server whenever the primary name
server is unavailable.

Nokia M11 User’s Manual

E Copyright Nokia Networks Oy

C33833001SE_00

12. Enable/disable DHCP server.
As a Dynamic Host Control Protocol (DHCP) server, your M11

can assign IP addresses to other devices on your LAN. If you want
your M11 to assign IP addresses, enter the first number of the IP
address range in the Start Address field and the last number of the
IP address range to the End Address field. Lease Time indicates
how often the PC will renew the DHCP lease.

If you want your M11 to relay the DHCP request to an external
server, you can do this by enabling the relay-agent and writing the
server’s IP address to the Server Address field.

Note

If you use M11 as a DHCP server, you must assign IP addresses
outside the M11’s DHCP address range to devices requiring static IP
addresses. Before M11 assigns an IP address to a DHCP client, it
verifies that no other device is using that address. However, network
conflicts can result when the M11 assigns an address in its DHCP
range to one device and another device configured to use that address
is turned on.

13. Change M11 Web-HTTP port number if needed.
Y ou must change the M11 internal W eb server port number default

value 80 if the same port number is used for pinhole functionality .
See Pinhole configuration example in Figure 5-12.

14. Change M1 1 telnet port number if needed.
You must change M11 internal telnet server port number default

value 23 if the same number is used for pinhole functionality.

15. Click Go to NAT Setup to configure the pinhole functionality if
needed.

3. Enable/disable IP.
IP Settings allow you to activate the IP layer function of the ATM

channel. Local address and peer address specify the basic IP
address parameters of the ATM channel interface (PPP over
A TM). If you write 0.0.0.0 in these fields, M1 1 will try to get them
from the network using either IPCP protocol (ATM channel using
PPP) or DHCP (ATM channel not using PPP).

Admin Restrictions is used to apply management restrictions to the
channel. If you select Admin-Disabled, you cannot manage M11
through this channel. If you select Admin-Only, this channel will
be used as a dedicated management channel.

Address mapping radio button activates/deactivates the Network
Address Port Translation (NAPT).

4. Configure Routing Information Protocol (RIP) settings.
Enable/disable dynamic routing for the active IP interface on the

ATM channel by selecting the corresponding radio buttons. If
RIP-send is selected, M11 sends RIP messages (version 1, 2 or
both) to the network. If RIP-receive is selected, M11 listens to RIP
messages from the network. RIP-send with V1-compat option
enables the sending of RIPv2 packets using broadcast.
RIP-receive with V1-compat option accepts both RIPv1 and
RIPv2 packets. If you enable Flush Routes, the learned routes are
deleted when the PPP connection is disconnected.

2. Enable/disable IP.
IP setting allows you to activate the IP layer function of the ATM

channel. Local address, net mask and broadcast address specify
the basic IP address parameters of the ATM channel interface (IP
over RFC1483). If you enter 0.0.0.0 in these fields, M11 will try to
get them from the network using either IPCP protocol (ATM
channel using PPP) or DHCP (ATM channel not using PPP).

Address mapping radio button activates/deactivates the Network
Address Port Translation (NAPT).

3. Configure Routing Information Protocol (RIP) settings.
Enable/disable dynamic routing for the active IP interface on the

ATM channel by selecting the corresponding radio buttons. If
RIP-send, is selected M11 sends RIP messages (version 1, 2 or
both) to the network. If RIP-receive is selected, M11 listens to RIP
messages from the network. RIP-send with V1-compat option
enables the sending of RIPv2 packets using broadcast.
RIP-receive with V1-compat option accepts both RIPv1 and
RIPv2 packets.

4. Add static routes to the routing table of the interface.
Enter destination address, net mask and gateway and click Add.

5.1.6 NAT pinhole page

The NA T pinhole page is used to make servers located in a LAN visible
to the W AN through a VCC. It allows fixed NAPT mapping between a
WAN/VCC IP address/port number and an internal LAN IP
address/port number. Separate entries must be created for TCP and
UDP ports.

The standard port numbers for the most common protocols are:

D HTTP (Hypertext Transfer Protocol) is TCP port 80
D FTP (File T ransfer Protocol) is TCP port 21
D SMTP (Simple Mail Transfer Protocol) is TCP port 25
D NNTP (Network News Transfer Protocol) is TCP port 119

Figure 5-11 NAT pinhole page

1. Enter a name for the pinhole entry. Select the protocol. Enter the
External Port Start and External Port End numbers. These define
the available range of allowed external ports (port number in W AN
interface). Enter Internal IP address (server IP address in LAN)
and Internal Port number (server port number in LAN). The
Internal Port number is the start of the internal port range.

2. Click Add.

3. Repeat until each server’s information is filled.

4. To remove an entry, click delete.

5. Change the integrated Web and telnet servers’ port numbers if
needed.

If you have servers (W eb or telnet servers) on your home network
which must be accessible from outside your home network, you
must change the default port numbers (80 and 23, respectively) of
the integrated Web and telnet servers of your M11.

6. Save new port numbers and restart M11.

Pinhole configuration example

The pinhole configuration example in Figure 5-12 can be used to allow
access from WAN to a Web server on the LAN. The example
configuration relays the traffic coming from the M1 1 WAN TCP port
80 to the LAN IP address 192.168.1.1 port 80. Port 80 is a standard
TCP port for HTTP. The port number of the M11’s integral W eb server
has been changed to 81.

Note

M11’s integral W eb server used for monitoring and configuration uses
also port 80 by default. You must change the server port by typing the
new port number in the W eb HTTP Port field or else the TCP traffic to
this port is directed to the M11 W eb server instead of the W eb server on
your LAN.

5.2 Command line interface

The Nokia M11 operating software includes a command line interface
(CLI) that lets you monitor and configure your M1 1 over a telnet or a
local serial console connection. You can use the CLI to enter and
update configuration settings in M11, monitor its performance, and
restart it. Some CLI commands are not available until certain
conditions are met. For example, you must turn a function on before
you can enter settings for that function.

The commands of the CLI are divided into two hierarchies: Root and
Config. The Root command hierarchy lets you monitor the
performance of your M11, display and reset M11 statistics, and issue
administrative commands to restart M11 functions. The Config
command hierarchy lets you configure the settings of your M1 1.

5.2.1 Starting and ending a CLI session

You can open a command line interface session by opening a telnet
connection from a workstation on your network to an M1 1 Ethernet or
ADSL port or by connecting a terminal to the console port on Nokia
M11.

Connecting with telnet

You initiate a telnet connection by issuing the following command
from an IP host that supports telnet (or a personal computer running a
telnet application such as Microsoft or NCSA Telnet).

telnet ADSL_ip_address

You must know the IP address of your Nokia M11 before you can
connect to it via a telnet connection to it. Y ou can use the command line
interface to configure the IP address of your M1 1.

Connecting through console port

You can connect a terminal or a terminal emulator to the console port
on the Nokia M11 front panel to configure, administer, and monitor
your Nokia M11. To use the Nokia M11 console, you need a special
cable (E64320.01) and either a terminal or a terminal emulator (such as
a personal computer with a terminal emulation application that
supports 9600-baud communication).

Management

E Copyright Nokia Networks Oy

C33833001SE_00

5-23

To connect your Nokia M11 to a terminal or terminal emulators:

1. Plug the special cable E64320.01 into the console port behind the
hatch on the Nokia M11 front panel.

2. Connect the other end of the serial cable to the serial port on your
terminal (or terminal emulator) or the serial port of your computer .

3. Turn on the terminal or run the terminal emulator program on your
computer.

Use the following settings to configure your terminal emulation
session:

Setting Value

Speed 9600
Parity None
Data bits 8
Stop bits 1
Duplex Full
Flow control None

The console interface uses the same command line interface as the
telnet interface.

Logging in

The command line interface login process emulates the login process
for a Unix host. If your Nokia M11 has been assigned a system
password, you must enter a username (up to 64 characters) and your
administrator, user-administrator or user password.

Entering your username lets Nokia M11 record your access; your
username is not used to validate your authorisation. The passwords
give you the following rights:

D User password view (but not change) M11 settings and

monitor statistics

D User-administrator change CHAP and PAP settings, configure

pinhole, Ethernet and router settings as well
as monitor M11 statistics

D Administrator change M11 settings and view statistics

Nokia M11 User’s Manual

C33833001SE_00

5-24

When you have logged in successfully, the command line interface
lists the username and the security level (admin, user-admin or user)
associated with the password you entered in the diagnostic log.

Issuing CLI commands

CLI commands consist of keywords and arguments. Keywords in a
Config command specify the action you want to take or the entity on
which you want to act. Arguments in a Config command specify the
values appropriate to your site. For example, the Config command

set

ip ip-ppp address ip_address consists of three keywords (ip,
ip-ppp, and address) and one argument (ip_address). When you

configure your M11, you replace command arguments with values
appropriate to your site. For example,

set ip ip-ppp address

192.31.222.57

The optional arguments are marked with braces {argument} and the
mandatory arguments with square brackets [ar gument].

Table 5-1 provides guidelines for formatting CLI commands.

Command compo­nent

Rules for entering CLI commands

Command word CLI commands must start with a command

word (set, show, delete). You can truncate
CLI commands to three characters (set,
sho, del). CLI commands are not case­sensitive: you can enter “SET“, “Set“ or
“set“.

Keywords Keywords are not case-sensitive. You can

enter “SYSTEM, “System“ or “system“ as a
keyword without changing its meaning. Key­words can be abbreviated to the length that
they are differentiated from other keywords.
For example, you can reduce the command

“set ip ip-ppp option on“ to “set i i
o on“.

Argument text Text strings can be as many as 32 characters

long, unless otherwise specified. Special
characters are represented using backslash
notation. Text strings may be enclosed in
double (”) or single (’) quote marks. If the text
string includes an embedded space, it must

be enclosed in quotes.
Numbers Type numbers as integers.
IP addresses Type IP addresses in dotted decimal notation

(nnn.nnn.nnn.nnn, where nnn = 0 to 255).

Table 5-1 CLI syntax

If a command is ambiguous or miskeyed, Nokia CLI prompts you to
enter additional information.

Ending a CLI session

You end a command line interface session by typing

quit in the Root

mode. Entering

quit in the Config mode switches the session into the

Root mode.

Using the CLI help facility

The help command lets you display on-line help for Root and Config
commands. To display a list of the commands available to you from
your current location in the command line interface hierarchy, type

5-26

help. To display help related to a particular command, type the

command followed by a question mark, for example show ?.

Saving settings

The

save command saves the working copy of the settings to restart

values. Y ou can save the changes you have made for a specific function
or for all functions in your Nokia M11. The Nokia M11 automatically
validates its settings when you save and displays a warning message if
the configuration is not correct.

5.2.2 Root command hierarchy

When you start a CLI session you begin in Root mode. The Root mode
lets you monitor the performance of your M11, display and reset M11
statistics, and issue M11 commands.

Root prompt

When you are in Root mode, the CLI prompt is the name of the M11
followed by a right angle bracket (>). For example, if you open a
command line interface to the M11 named “Kilo” you would see

Kilo> as your CLI prompt.

Root command shortcuts

You can truncate most commands in the command line interface to
their shortest unique string. For example, you can use the truncated
command

q in place of the full quit command to exit the command

line interface.
The only command you cannot truncate is restart. To prevent

accidental interruption of communications, you must enter the

restart command in its entirety.

You can use the !! command to repeat the last command you entered.
You can press the CTRL+P or ESC+K key sequences to obtain the same
result.

Root commands

You can get a list of the Root commands by typing

? at the Root

prompt.

5.2.3 Config command hierarchy

The Config mode lets you configure the parameters of your M11. The
command hierarchy consists of nodes and subnodes. Each node
contains the configurable parameters of that particular function.

Config prompt

Y ou reach the configuration mode of the M11 CLI by typing

config at

the Root prompt. When you are in Config mode, the CLI prompt
consists of the name of your M11 followed by your current node in the
hierarchy and two angle brackets (>>). For example, when you enter
Config mode (by typing config at the Root prompt), the M11

(top)>> prompt reminds you that you are at the top of the Config

hierarchy. If you move to the ip node in the Config hierarchy (by
typing ip at the Config prompt), the prompt changes to M11 (ip)>> to
identify your current location.

Navigating the Config hierarchy

You start at the

top when you enter Config mode. The command line

interface reminds you of your location by showing your current node
after the M11 name:

M11 (top)>>

D Moving from Config to Root

You can navigate from anywhere in the Config hierarchy back to
the Root level by issuing the

quit command at the Config

command prompt and pressing

ENTER.

M11 (top)>> quit
M11>

D Moving from top to a subnode

You can navigate from the top node to a subnode by entering the
node name (or the significant letters of the node name) at the
Config prompt and pressing Enter. For example, you move to the
ip subnode by entering

ip and pressing Enter .

M11 (top)>> ip
M11 (ip)>>

As a shortcut, you can use the significant letters of the node in
place of the full node name at the Config prompt. The significant
characters of a node name are the letters that uniquely identify the
node. For example, only the

atm Config node starts with a, you

could enter one letter (a) to move to the atm node.

M11 (top)>> a
M11 (atm)>>

You would have to enter two or more letters (ppp) to move to the
PPP node, since its node name shares the first letter with the
preferences node.

D Jumping down several nodes at once

You can jump down several levels in the Config hierarchy by
entering the complete path to a node.

M11 (top)>> ip ip-ppp
M11 (ip ip-ppp)>>

D Moving up one node

Y ou can move through the Config hierarchy one node at a time by
entering the

up command.

M11 (ip ip-ppp)>> up
M11 (ip)>>

D Jumping to the top node

You can jump to the top level from anywhere in the Config
hierarchy by entering the

top command.

M11 (ip ip-ppp)>> top
M11 (top)>>

D Moving from one subnode to another

You can move from one subnode to another by entering a partial
path that identifies how far back to climb.

M11 (ip ip-ppp)>> ppp module
M11 (ppp module)>>

D Moving from any subnode to any other subnode

Y ou can move from any subnode to any other subnode by entering
a partial path that starts with a top-level Config command.

M11 (ip ip-ppp)>> ip gateway
M11 (ip gateway)>>

D Issuing commands without changing nodes

You can issue a complete Config command from anywhere in the
hierarchy without changing your current node.

M11 (ip ip-ppp)>> set system diag high
M11 (ip ip-ppp)>>

Here, the diagnostic level is set high in the system without jumping
to the node first.

Displaying current settings
Y ou can use the

show command to display the current Root settings of

your M11. When you are in Config mode, you use the

show command

to display the current Config settings. If you enter the show command
at the top level of the Config hierarchy, the command line interface
displays the settings for all enabled functions in the M1 1. If you issue
the

show command at an intermediate node, you see all settings for that

node and its subnodes.

Stepping through M11 configuration

The Nokia M11 command line interface includes a step mode to
automate the process of entering configuration settings. When you use
the Config step mode, the CLI prompts you for all required and
optional information. You can enter the configuration values
appropriate for your site without having to enter complete CLI
commands.

When you are in step mode, the CLI prompts you to enter required and
optional settings. If a setting has a default value or a current setting, the
command line interface displays the default value for the command in
parentheses. If a command has a limited number of acceptable values,
those values are presented in brackets, with each value separated by a
vertical line. For example, the following CLI step command indicates
that the default value is off and that valid entries are limited to on and
off.

option (off) [on|off]: on

You can accept the default value for a field by pressing the Enter key.
To use a different value, type it in and press Enter.

Y ou can enter the Config step mode by typing set from the top node of
the Config hierarchy . Y ou can enter step mode for a particular node by
typing

set node_name. For example:

Diagnostic Level (High): medium

See Chapter 4 for step mode installation examples.

V alidating your configuration

You can use the

validate command to make sure that your

configuration settings have been entered correctly. If you use the

validate command, M11 verifies that all required settings are

present and that the settings are consistent.

M11 (top)>> validate
Error: Subnet mask is incorrect
Global Validation did not pass inspection!

You can use the validate command to verify your configuration
settings at any time. Your M11 automatically validates your
configuration any time you save a modified configuration.
