HyperTerminal Interface with new IP address
You must save the new IP address by typing the command series config save
and pressing Enter. This will save the new IP address for the Router and store it
in the device’s flash memory. You may now disconnect the terminal emulator and
access the device using the web-based management interface for configuration.
For more thorough instructions on using the out-of-band console manager, see
Chapter 7.

Using the Console Manager
Settings for the Router can be configured via the RS-232 console port connection
using terminal emulation software such as Microsoft HyperTerminal included
with Microsoft’s operating systems. This chapter lists and describes a few of the
most essential command sets that might be used by the typical user. This chapter
is not intended to be a complete list of the commands available.
General Use
To use a terminal emulation interface with the device, the terminal parameters
will need to be set to:
VT-100/ANSI compatible
Terminal keys enabled
9,600 baud
8 data bits
No parity
One stop bit
With the correct parameters set and the RS-232 connection established you
should be able to use the keyboard to communicate with the device. If the Router
is powered on when the terminal interface appears, depress the Enter key to
bring up the initial prompt. This will be the IP address of the device. For
information about changing the IP address, please read the section in Chapter 6.
If at any time you want to view a list of commands available in the particular
mode you are currently operating, type help
 and press Enter. This will bring up
a list of the commands available in the current mode. For example, type help
after the initial IP address prompt and you will see a menu similar to this:
ap
chips
edd
ip_filter
oamloop
restart
webserveratm
config
ethernet
isfs
portcli
snmpbridge

dhcpserver
flashfs
led
r1483
uptimebun
diap
ip
nat
reflect
version

To see a list of available commands and command syntax along with brief
explanation of the command, type  help all
 and depress Enter. Remember that
the console interface commands are case sensitive.
Typing any of the commands listed above and depressing Enter will put the
console interface into that command mode. For example, form the IP address
prompt type ip
 and depress Enter. This will put the interface into “ip
” where it
can now accept ip mode commands. While in ip mode or any other command
mode you may again type help or help all to list the commands available in that
mode. You will see the command appear after the IP address and before the
“greater than” sign. If you type help
 in ip mode you would see a menu such as
this:
?
disable
nat
rip
statsarp
enable
norelay
route
subnetconfig
help
ping
routes
versiondevice
ipatm
relay
snmp
If you at any time wish to return to the original undefined command prompt (the
first IP address prompt), type home
 and depress Enter and you will again see the
IP address prompt.
The commands restart
, uptime
 and version
 are not command modes. The
restart command will restart (reboot) the Router. Remember that any changes
made to the configuration must be saved before the Router is restarted or the
changes will be lost. The uptime and version commands simply list the uptime
(amount of time the Router has been continuously operating) and the software
version of the unit.
Saving Changes
To save changes made to the Router configuration type config save
 and press
Enter, the current settings will be saved to nonvolatile RAM.
Finding the Password
If you forget the user name and password that allows you to access the web-based
manager you can retrieve this information using the console terminal interface.
To do this type flashfs cat initweb
 and you will see the user name and
password listed.

IP Concepts
This appendix describes some basic IP concepts, the TCP/IP addressing scheme
and show how to assign IP Addresses.
When setting up the Router, you must make sure it has a valid IP address. Even
if you will not use the WAN port (ADSL port), you should, at the very least, make
sure the Ethernet LAN port is assigned a valid IP address. This is required for
telnet, in-band SNMP management, and related functions such as “trap”
handling and TFTP firmware download.
IP Addresses
The Internet Protocol (IP) was designed for routing data between network sites
all over the world, and was later adapted for routing data between networks
within any site (often referred to as “subnetworks” or “subnets”). IP includes a
system by which a unique number can be assigned to each of the millions of
networks and each of the computers on those networks. Such a number is called
an IP address.
To make IP addresses easy to understand, the originators of IP adopted a system
of representation called “dotted decimal” or “dotted quad” notation. Below are
examples of IP addresses written in this format:
201.202.203.204        189.21.241.56        125.87.0.1
Each of the four values in an IP address is the ordinary decimal (base 10)
representation of a value that a computer can handle using eight “bits” (binary
digits — 1s and 0s). The dots are simply convenient visual separators.
Zeros are often used as placeholders in dotted decimal notation; 189.21.241.56
can therefore also appear as 189.021.241.056.
IP networks are divided into three classes on the basis of size. A full IP address
contains a network portion and a “host” (device) portion. The network and host
portions of the address are different lengths for different classes of networks, as
shown in the table below. 
						

							DSL-500 ADSL Router User’s Guide
72
Networks attached to the Internet are assigned class types that determine the
maximum number of possible hosts per network. The previous figure illustrates
how the net and host portions of the IP address differ among the three classes.
Class A is assigned to networks that have more than 65,535 hosts; Class B is for
networks that have 256 to 65534 hosts; Class C is for networks with less than
256 hosts.

.0.0)65,534
C2,097,150 192.0.1(.0) to
223.255.254(.0)254
Note:
 All network addresses outside of these ranges (Class D and E) are either reserved
or set aside for experimental networks or multicasting.
When an IP addresss host portion contains only zero(s), the address identifies a
network and not a host. No physical device may be given such an address.
The network portion must start with a value from 1 to 126 or from 128 to 223.
Any other value(s) in the network portion may be from 0 to 255, except that in
class B the network addresses 128.0.0.0 and 191.255.0.0 are reserved, and in
class C the network addresses 192.0.0.0 and 223.255.255.0 are reserved.
The value(s) in the host portion of a physical devices IP address can be in the
range of 0 through 255 as long as this portion is not all-0 or all-255. Values
outside the range of 0 to 255 can never appear in an IP address (0 to 255 is the
full range of integer values that can be expressed with eight bits).
The network portion must be the same for all the IP devices on a discrete
physical network (a single Ethernet LAN, for example, or a WAN link). The host
portion must be different for each IP device — or, to be more precise, each IP-
capable port or interface — connected directly to that network. 
						

							DSL-500 ADSL Router User’s Guide
73
The network portion of an IP address will be referred to in this manual as a
network number
; the host portion will be referred to as a host number
.
To connect to the Internet or to any private IP network that uses an Internet-
assigned network number, you must obtain a registered IP network number from
an Internet-authorized network information center. In many countries you must
apply through a government agency, however they can usually be obtained from
your Internet Service Provider (ISP).
If your organizations networks are, and will always remain, a closed system with
no connection to the Internet or to any other IP network, you can choose your
own network numbers as long as they conform to the above rules.
If your networks are isolated from the Internet, e.g. only between your two
branch offices, you can assign any IP Addresses to hosts without problems.
However, the Internet Assigned Numbers Authority (IANA) has reserved the
following three blocks of IP Addresses specifically for private (stub) networks:
ClassBeginning
Address
Ending Address
A 10.0.0.0 10.255.255.255
B 172.16.0.0 172.31.255.255
C 192.168.0.0 192.168.255.255
It is recommended that you choose private network IP Addresses from the above list. For
more information on address assignment, refer to RFC 1597, Address Allocation for Private
Internets and RFC 1466, Guidelines for Management of IP Address Space.
Subnet Mask
In the absence of subnetworks, standard TCP/IP addressing may be used by
specifying subnet masks as shown below.
IP ClassSubnet Mask
Class A 255.0.0.0
Class B 255.255.0.0
Class C 255.255.255.0
Subnet mask settings other than those listed above add significance to the
interpretation of bits in the IP address. The bits of the subnet mask correspond
directly to the bits of the IP address. Any bit an a subnet mask that is to
correspond to a net ID bit in the IP address must be set to 1.

DSL-500 Firmware Upgrade Utility
You can update system firmware using the DSL-500 Firmware Upgrade Utility.
To upgrade the Router’s firmware you must have installed this software on the
PC you wish to use for this purpose. Install the utility by clicking the file titled
setup.exe
 located on the Installation CD-ROM. It will be installed automatically.
It is recommended that the PC be directly connected to the Router using a
crossed cable, however you may upgrade it through the LAN from a remote host.
You also need to download the latest firmware version file from the D-Link web
site to the PC on which you will use the Upgrade Utility. Instructions for
downloading the firmware are located on the web site at www.dlink.com.
To launch the DSL-500 Firmware Upgrade Utility, click on the icon. Allow a few
moments for the software to discover the Router on the network. After the
discovery phase the following window will appear. You will see all the DSL-500
Routers on your network. You can identify individual devices by either its IP
address or its MAC address. Select the device you wish to upgrade by double
clicking on it.
When you select a Router to upgrade you will be prompted for a password. The
default password is admin
. If you want to change the password, you can change
it using the console manager interface as described in Chapter 6. 
						

							DSL-500 ADSL Router User’s Guide
75
Enter the password and click OK.
In the new window you will see the MAC address of the Router and the IP
address of the PC you are using. The PC and the Router must be on the same
subnet for the upgrade to be completed. The upgrade utility will suggest a new IP
address to be temporarily assigned to the device during the firmware upgrade
procedure. Check the suggested IP address listed for the Router to be sure that it
does not conflict with any existing IP addresses on your network. To change the
temporary IP address of the Router, type in an available IP address in the space
provided. You should change only the host portion of the address.
To upload the new firmware to the selected Router click the ‘Upgrade’ button.
The utility will automatically load the new firmware. During the upgrade process
it is important that you allow the entire file to load onto the device. Do not turn
off the Router while the flash memory is being updated. A warning will appear
during the upgrade reminding you not to power off the device.
When the new firmware has been successfully loaded a new window will inform
you of the upgrade and tell you that the Router has been restarted. Click OK to
proceed.
