Preparing to Connect to a Network
When setting up your router, consider distance limitations and potential
electromagnetic interference (EMI) as defined by the EIA.
The serial, console, and auxiliary ports contain safety extra-low voltage
(SELV) circuits. BRI circuits are treated like telephone-network voltage
(TNV) circuits. Avoid connecting SELV circuits to TNV circuits.
Installing the HP AdvanceStack Internet Router
Preparing to Connect to a Network
ISDN Connections
Use a BRI cable to connect the router directly to an ISDN. (See table 2-1.)
WARNING
WARNING
Network hazardous voltages are present in the BRI cable. If you detach the
BRI cable, detach the end away from the router to avoid possible electric
shock. Network hazardous voltages are also present on the system card in the
area of the BRI port (RJ-45 connector), regardless of when power is turned
OFF.
The ISDN connection is regarded as a source of voltage that should be
inaccessible to user contact. Do not attempt to tamper with or open any public
telephone operator (PTO)-provided equipment or connection hardware. Any
hardwired connection (other than by nonremovable, connect-one-time-only
lug) must be made only by PTO staff or suitably trained engineers.
Table 2-1 lists the specifications for ISDN BRI Cables. Refer to the section
“ISDN BRI Port and Cable Pinouts” in appendix A, “Cable Specifications” for
pinouts.

Installing the HP AdvanceStack Internet Router
Preparing to Connect to a Network
Synchronous Serial Connections
Before you connect a device to the synchronous serial port, you will need to
know the following:
■The type of device, DTE or DCE, you are connecting to the synchronous
serial interface
■The type of connector, male or female, required to connect to the device.
■The signaling standard required by the device.
DTE or DCE
A device that communicates over a synchronous serial interface is either a
DTE or DCE device. A DCE device provides a clock signal that paces the
communications between the devices and the router. A DTE device does not
provide a clock signal. DTE devices usually connect to DCE devices. The
documentation that came with the device should indicate whether it is a DTE
or DCE device. (Some devices have a jumper to select either mode.) If you
cannot find the information in the documentation, refer to table 2-2 to help
you select the proper device type.

Preparing to Connect to a Network
Signaling Standards Supported
The synchronous serial port supports the following signaling standards: EIA/
TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530. You can order a DB-60 shielded
serial transition cable from HP that has the appropriate connector for the
standard you specify. The router end of the shielded serial transition cable has
a DB-60 connector, which connects to the DB-60 port on the rear panel of the
router. The other end of the serial transition cable is available with the
connector appropriate for the standard you specify. The documentation for
the device you want to connect should indicate the standard used for that
device. The synchronous serial port can be configured as DTE or DCE (except
EIA-530, which is DTE only), depending on the attached cable. To order a
shielded serial transition cable, refer to the section “Ordering Information” in
chapter 1 “HP AdvanceStack Internet Router Overview” and appendix A,
“Cable Specifications”.
Installation
NOTE
All serial ports configured as DTE require external clocking from a CSU/DSU
or other DCE device.
Although attempting to manufacture your own serial cables is not recommended (because of the small size of the pins on the DB-60 serial connector),
cable pinouts are provided in appendix A, “Cable Specifications”.
Distance Limitations
Serial signals can travel a limited distance at any given bit rate; generally, the
slower the data rate, the greater the distance. All serial signals are subject to
distance limits, beyond which a signal degrades significantly or is completely
lost.
Table 2-3 lists the maximum speeds and distances for EIA/TIA-232 signals.
This signalling standard supports unbalanced circuits at signal speeds up to
64 Kbps.

CAUTION
The EIA/TIA-449 and V.35 interfaces support data rates up to 2.048 Mbps.
Exceeding this maximum could result in loss of data and is not recommended.
Console and Auxiliary Port Considerations
All router models include an asynchronous serial console and auxiliary port.
The console and auxiliary ports provide access to the router either locally
(with a console terminal) or remotely (with a modem). This section discusses
important cabling information to consider before connecting a console
terminal (an ASCII terminal or PC running terminal emulation software) to
the console port or modem to the auxiliary port.
The main difference between the console and auxiliary ports is that the
auxiliary port supports hardware flow control and the console port does not.
Flow control paces the transmission of data between sending device and a
receiving device. Flow control ensures that the receiving device can absorb
the data sent to it before the sending device sends more. When the buffers on
the receiving device are full, a signal is sent to the sending device to suspend
transmission until the data in the buffers has been processed. Because the
auxiliary port supports flow control, it is ideally suited for use with the highspeed transmissions of a modem. Console terminals transmit at slower speeds
than modems; therefore, the console port is ideally suited for use with console
terminals.
2-6
Installing the HP AdvanceStack Internet Router
Preparing to Connect to a Network
Console Port Connections
The router includes an EIA/TIA-232 asynchronous serial console port (RJ-45).
Depending on the cable and the adapter used, this port will appear as a DTE
or DCE device at the end of the cable. Your router comes with cables and
adapters to connect a console terminal (an ASCII terminal or PC running
terminal emulation software) to the console port. To connect an ASCII
terminal to the console port, use the RJ-45 roll-over cable with the female
RJ-45-to-DB25 adapter (labeled Terminal). To connect a PC running terminal
emulation software to the console port, use the RJ-45 roll-over cable with the
female RJ-45-to-DB-9 adapter (labeled Terminal). The default parameters for
the console port are 9600 baud, 8 data bits, no parity, and 2 stop bits. The
console port does not support hardware flow control. For detailed information about installing a console terminal, see the section “Connecting the
Console Terminal and Modem” later in this chapter. See appendix A, “Cable
Specifications” for cable and port pinouts.
Auxiliary Port Connections
The router includes an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45)
that supports flow control. Depending on the cable and the adapter used, this
port will appear as a DTE or DCE device at the end of the cable. Your router
includes a cable and an adapter to connect a modem to the auxiliary port. To
connect a modem to the auxiliary port, use the RJ-45 roll-over cable with the
male RJ-45-to-DB-25 adapter (labeled Modem). For detailed information about
connecting devices to the auxiliary port, see the section, “Connecting the
Console Terminal and Modem” later in this chapter. See appendix A, “Cable
Specifications” for cable and port pinouts.

and contains the following sections:
■Booting the Router for the First Time
■Configuring the Router for the First Time
■Cisco IOS Software Basics
■Configuring ISDN
■Verifying Network Connectivity
■Getting More Information
This chapter provides minimum software configuration information; it is not
meant as comprehensive router configuration instructions. Detailed software
configuration information is available in the Cisco IOS configuration guide
and command reference publications. These publications are available on the
documentation CD that came with your router or you can order printed copies.
Refer to the section “Ordering Information” in chapter 1 “HP AdvanceStack
Internet Router Overview”.

Configuration
Booting the Router for the First Time
Each time you power on the router, it goes through the following boot
sequence:
1. The router goes through power-on self-test diagnostics to verify basic
operation of the CPU, memory, and interfaces.
2. The system bootstrap software (boot image) executes and searches for a
valid Cisco IOS image (router operating system software). The source of
the Cisco IOS image (Flash memory or a Trivial File Transfer Protocol
[TFTP] server) is determined by the configuration register setting. The
factory-default setting for the configuration register is 0x2102, which
3-1
Configuring the HP AdvanceStack Internet Router
Configuring the Router for the First Time
indicates that the router should attempt to load a Cisco IOS image from
Flash memory. Use the “show version” command at the privileged EXEC
prompt to show the setting.
3. If after five attempts a valid Cisco IOS image is not found in Flash memory,
the router reverts to boot ROM mode (which is used to install or upgrade
a Cisco IOS image).
4. If a valid Cisco IOS image is found, then the router searches for a valid
configuration file.
5. If a valid configuration file is not found in NVRAM, the router runs the
System Configuration Dialog so you can configure it manually. For normal
router operation, there must be a valid Cisco IOS image in Flash memory
and a configuration file in NVRAM.
The first time you boot your router, you will need to configure the router
interfaces and then save the configuration to a file in NVRAM.
Configuring the Router for the First Time
Configuration
NOTE
3-2
You can configure the router using one of the following procedures, which are
described in this section:
■System Configuration Dialog—Recommended if you are not familiar with
Cisco IOS commands.
■Configuration mode—Recommended if you are familiar with Cisco IOS
commands.
AutoInstall—Recommended for automatic installation if another router
■
running Cisco IOS software is installed on the network. This configuration
method must be set up by someone with experience using Cisco IOS
software.
Acquire the correct network addresses from your system administrator or
consult your network plan to determine the correct addresses before you
begin to configure the router.
Proceed with the procedure that best fits the needs of your network configuration and Cisco IOS software experience level. If you will be using configuration mode or AutoInstall to configure the router, and you would like a quick
Configuring the HP AdvanceStack Internet Router
review of the Cisco IOS software, refer to the section “Cisco IOS Software
Basics” later in this chapter. Otherwise, proceed with the next section “Using
the System Configuration Dialog”.
Configuring the Router for the First Time
Using the System Configuration Dialog
If you do not plan to use AutoInstall, make sure all the WAN cables are
disconnected from the router. This will prevent the router from attempting to
run the AutoInstall process. The router will attempt to run AutoInstall whenever you power it ON if there is a WAN connection on both ends and the router
does not have a configuration file stored in NVRAM. It can take several
minutes for the router to determine that AutoInstall is not connected to a
remote TCP/IP host.
If your router does not have a configuration (setup) file and you are not using
AutoInstall, the router will automatically start the setup command facility. An
interactive dialog called the System Configuration Dialog appears on the
console screen. This dialog helps you navigate through the configuration
process by prompting you for the configuration information necessary for the
router to operate.
Many prompts in the System Configuration Dialog include default answers,
which are included in square brackets following the question. To accept a
default answer, press Return; otherwise, enter your response.
This section gives an example configuration using the System Configuration
Dialog. When you are configuring your router, respond as appropriate for your
network.
At any time during the System Configuration Dialog, you can request help by
typing a question mark (?) at a prompt.
Before proceeding with the System Configuration Dialog, obtain from your
system administrator the node addresses and the number of bits in the subnet
field (if applicable) of the router ports.
Take the following steps to configure the router using the System Configuration Dialog:
1. Connect a console terminal to the console port on the rear panel of your

Proceed to the section “Cisco IOS Software Basics” for more information
about the Cisco IOS software.
Using Configuration Mode
You can configure the router manually if you do not want to use AutoInstall
or the prompt-driven System Configuration Dialog. Take the following steps
to configure the router manually:
1. Connect a console terminal following the instructions in the section
“Connecting the Console Terminal and Modem” in chapter 2 “Installing
the HP AdvanceStack Internet Router”, and then turn the power ON on
the host device. (Note that the router may also be installed in a host device
with the power already on.)
2. When you are prompted to enter the initial dialog, enter no to go into the
normal operating mode of the router:
Would you like to enter the initial dialog? [yes]: no
3. After a few seconds you will see the user EXEC prompt (Router>). Enter
the enable command to enter privileged EXEC mode. You can only make
configuration changes in privileged EXEC mode:
Configuration
Router> enable
The prompt changes to the privileged EXEC prompt:
Router#
4. Enter the configure terminal command at the privileged EXEC prompt
to enter configuration mode:
Router# configure terminal
You can now enter any changes you want to the configuration. You will
probably want to perform the following tasks:
•Assign a host name for the router using the hostname command.
•Enter an enable secret password using the enable password
command.
•Assign addresses to the interfaces using the protocoladdress
command.
•Specify which protocols to support on the interfaces.
3-10
Configuring the HP AdvanceStack Internet Router
Configuring the Router for the First Time
Refer to the Cisco IOS configuration guide and command reference publications for more information about the commands you can use to
configure the router. To verify the configuration entries, use the “write
terminal” command at the privileged EXEC prompt.
5. When you are finished configuring the router, enter the exit command
until you return to the privileged EXEC prompt (Router#).
6. To save the configuration changes to NVRAM, enter the copy running-config startup-config command at the privileged EXEC prompt.
The router will now boot with the configuration you entered.
Using AutoInstall
The AutoInstall process is designed to configure the router automatically after
connection to your WAN. In order for AutoInstall to work properly, a Transmission Control Protocol/Internet Protocol (TCP/IP) host on your network
must be preconfigured to provide the required configuration files. The TCP/
IP host may exist anywhere on the network as long as the following two
conditions are maintained:
1. The host must be on the remote side of the router’s synchronous serial
connection to the WAN.
2. User Datagram Protocol (UDP) broadcasts to and from the router and the
TCP/IP host must be enabled.
This functionality is coordinated by your system administrator at the site
where the TCP/IP host is located. You should not attempt to use AutoInstall
unless the required files have been provided on the TCP/IP host. For more
information, refer to the Cisco IOS configuration guide and command reference publications.
Take the following steps to prepare your router for the AutoInstall process:
1. Attach the WAN cable to the router.
2. Power ON or Reset the router.
3. The router will load the operating system image from Flash memory. If
the remote end of the WAN connection is connected and properly configured, the AutoInstall process will begin.
3-11
Configuration
Configuring the HP AdvanceStack Internet Router
Cisco IOS Software Basics
4. If AutoInstall completes successfully, enter the copy running-config
startup-config command in privileged EXEC mode to write the configu-
ration data to the router’s NVRAM:
Router# copy running-config startup-config
Taking this step saves the configuration settings that the AutoInstall
process created to the router’s NVRAM. If you do not do this, the configuration will be lost the next time you reload the router.

Cisco IOS Modes of Operation
The Cisco IOS software provides access to several different command modes.
Each command mode provides a different group of related commands.
For security purposes, the Cisco IOS software provides two levels of access
to commands: user and privileged. The unprivileged user mode is called user
EXEC mode. The privileged mode is called privileged EXEC mode and
requires a password. The commands available in user EXEC mode are a subset
of the commands available in privileged EXEC mode.
Table 3-2 describes some of the most commonly used modes, how to enter the
modes, and the resulting prompts. The prompt helps you identify which mode
you are in and, therefore, which commands are available to you.

Cisco IOS Software Basics
Almost every configuration command also has a “no” form. In general, use the
“no” form to disable a feature or function. Use the command without the
keyword “no” to reenable a disabled feature or to enable a feature that is
disabled by default. For example, IP routing is enabled by default. To disable
IP routing, enter the no ip routing command and enter ip routing to reenable
it. The Cisco IOS software command reference publication provides the
complete syntax for the configuration commands and describes what the no
form of a command does. Note that you cannot override or modify a parameter
of an existing command. It must first be deleted and then use “no” form.
Getting Context-Sensitive Help
In any command mode, you can get a list of available commands by entering
a question mark (?).
Router> ?
To obtain a list of commands that begin with a particular character sequence,
type in those characters followed immediately by the question mark (?). Do
not include a space. This form of help is called word help, because it completes
a word for you.
Configuration

To list keywords or arguments, enter a question mark in place of a keyword
or argument. Include a space before the question mark. This form of help is
called command syntax help because it reminds you which keywords or
arguments are applicable based on the command, keywords, and arguments
you have already entered.
Router# configure ?

You can also abbreviate commands and keywords by entering just enough
characters to make the command unique from other commands. For example,
you can abbreviate the show command to sh.

Configuring the HP AdvanceStack Internet Router
Configuring ISDN
Saving Configuration Changes
Any time you make changes to the router configuration, you must save the
changes to memory because if you do not they will be lost if there is a system
reload or power outage. There are two types of configuration files: the running
(current operating) configuration and the startup configuration. The running
configuration is stored in RAM; the startup configuration is stored in NVRAM.
To display the current running configuration, enter the show running-config
command. Enter the copy running-config startup-config command to save
the current running configuration to the startup configuration file in NVRAM.
To display the startup configuration, enter the show startup-config
command. Enter the copy startup-config running-config command to write
the startup configuration to the running configuration:
To erase both configuration files (and start over), enter the write erase and
reload commands:
Router> enable
Router# write erase
Router# reload
This command sequence will erase the entire router configuration in RAM and
NVRAM and reload the router.
Configuring ISDN
This section describes a recommended ISDN configuration for one or two B
channels. In the examples that follow, the BRI port is configured for IP routing,
Challenge Handshake Authentication Protocol (CHAP), and Point-to-Point
Protocol (PPP) encapsulation.
For your reference, an example configuration follows in the next section,
“Example ISDN Connection”. You may want to refer to “Example ISDN
Configuration” during this procedure.
Configuration
3-15
Configuring the HP AdvanceStack Internet Router
Configuring ISDN
Take the following steps to configure the router for a basic ISDN PPP connection on a single B channel or two B channels, substituting the correct
addresses and host names as appropriate for your network:
1. Enter privileged EXEC mode:
Router> enable
password: enablepassword
2. Enter the configure terminal command to enter global configuration
mode. Then enter the host name of the current router, the user name of
the target router (the router to which packets will be sent), and the
password that the routers will use for CHAP caller identification. The user
name and password are case sensitive and must match the host name and
password of the target router (even if it is not a Cisco router):
3. Enter the isdn switch-type command to configure the ISDN switch type
(such as basic-5ess, basic-dms100, or basic-ni1). Refer to 3-1, earlier in
this chapter, for a list of ISDN switch types supported.
Configuration
Router (config)# isdn switch-type switch-type
4. Configure the IP address and subnet mask for the LAN interface:
Router (config)# interface typeport_number
Router (config-if)# ip addressipaddress subnetmask
5. Configure the IP address and subnet mask for the BRI interface:
Router (config-if)# interface bri port_number
Router (config-if)# ip addressipaddress subnetmask
6. If you are using an ISDN switch type (such as Basic NI1 or DMS-100) that
requires a service profile identifier (SPID), enter the SPID and optional
local directory number (LDN). The SPID and LDN are assigned by the
ISDN service provider.
The SPID is a number that identifies the service to which you have
subscribed. A SPID is not required for AT&T 5ESS service configured for
a point-to-point connection.
The LDN is an optional seven-digit phone number for the channel.
7. Configure the router for PPP encapsulation and CHAP authentication:
Router (config-if)# encapsulation ppp
Router (config-if)# ppp authentication chap
8. Enter the load-threshold or ppp multilink command to set up a second
B channel.
For bandwidth on demand, enter the load-threshold command to set the
ISDN load threshold. The load threshold determines the percentage of
network load at which the second ISDN B channel is activated. The value
ranges from 1 to 255 (100 percent). In the following example, the value of
128 means that when the first B channel reaches 50 percent of its bandwidth capacity (128 equals 50 percent of 255), the second B channel will
activate to assist with the bandwidth load:
Router (config-if)# dialer load-threshold 128
Alternatively, you can use Multilink PPP to activate a second ISDN line.
For Multilink PPP to work, the router must be running Cisco IOS
Release 11.0(3) or a later release (cannot be a non-IOS HP router), and
both the current router and target router must support Multilink PPP:
Router (config-if)# ppp multilink
9. Enter the dialer map command to provide the information necessary to
successfully route packets to the target router. Do not use periods or
hyphens when entering the number to dial:
Router (config-if)# dialer map protocol targetBRIport_ipaddress name
targetrouter_number
10. Enter the dialer-group command to specify the number of the group
permitted to access the router:
Router (config-if)# dialer-group groupnumber
11. Enter the exit command to exit interface configuration mode.
3-17
Configuration
Configuring the HP AdvanceStack Internet Router
Configuring ISDN
12. Enter the dialer list command to specify the groups and protocols
permitted to access the router:
13. Configure a static route to allow connection to the target router’s LAN.
Enter the IP address and subnet mask of the target router’s LAN interface,
and the IP address of the target router’s BRI port:
Router (config)# ip route targetrouter_ipnetwork subnetmask
targetBRIport_ipaddress
14. Enter the exit command to exit global configuration mode.
15. Enter the copy running-config startup-config command to save the
configuration to NVRAM.

Verifying Network Connectivity
Verifying Network Connectivity
After you have installed and configured the router, you can use the following
commands in user EXEC mode to verify network connectivity:
■
telnet—Logs in to a remote node
■ping—Sends a special datagram to the destination device, then waits for
a reply datagram from that device
■trace—Discovers the routes that packets take when traveling from one
router to another
If there is a problem with network connectivity, refer to the section “Reading
the LEDs” in chapter 4 “Troubleshooting” and check the cable connections. If
there is still a problem, check the router configuration.

CD-ROM accompanying the router. You can also access “Technical Assistance” at the World Wide Web URL http://www.cisco.com (Cisco Connection
Online) for a list of frequently asked questions and other technical tips.
Upgrading the Boot ROMs
The Boot ROMs are not user upgradeable. Please contact your nearest HP field
service representative for further information.
Recovering Lost Passwords
This section explains how to recover the following types of passwords:
■An enable secret password (a very secure, encrypted password)—
Available on routers running Cisco IOS Release 10.3(2) or later.
■An enable password (a less secure, nonencrypted password)—Used
when the enable secret password does not exist.
■A console password—Prevents unauthorized users from attempting to
change the router configuration. When a console password is set, you
must provide a password to log in to the console and access user EXEC
mode.
Maintenance
The key to recovering a lost enable password is to set the configuration
register so that the contents of NVRAM are ignored (0x142), which allows you
to see the password. The enable secret password is encrypted and cannot be
recovered; it must be replaced. The enable and console passwords might be
encrypted or clear text.
Take the following steps to recover a lost password:
1. Plan for about one-half hour of system downtime. The password recovery
procedure requires a system reload.
2. Connect a terminal to the console port on the rear panel of the router.
Make sure the terminal is configured to operate at 9600 baud, 8 data bits,
no parity, and 2 stop bits.

Troubleshooting
3. Enter the show version command to display the existing configuration
register value. The configuration register value is on the last line of the
display. Note whether the configuration register is set to enable or disable
Break.
4. The factory-default configuration register value is 0x2102. Notice that the
third digit from the right in 0x2102 is 1, which disables Break. If the third
digit is not 1, Break is enabled.
5. If the configuration register is set to disable Break, power cycle the router
or press the reset button on the router’s front panel. (Turn the router OFF,
wait five seconds, and then turn the router ON again.) Within 60 seconds
of turning ON the router, press the Break key or send a Break signal. The
ROM monitor prompt (>) appears.
6. If the configuration register is set to enable Break, press the Break key or
send a Break signal to the router.
NOTE
If your keyboard does not have a Break key, refer to your terminal or terminal
emulation software documentation for information about how to send a Break
signal to the router.
7. Enter the o/r command to reset the configuration register to boot from
the boot ROMs and ignore NVRAM:
> o/r 0x142
8. Enter the initialize command to initialize the router:
> initialize
9. The router power cycles and the configuration register is set to 0x142. The
router boots the system image in Flash memory and the System Configuration Dialog appears:
--- System Configuration Dialog ---
10. Enter no in response to the System Configuration Dialog prompts until
the following message appears:
Press RETURN to get started!
11. Press Return.

12. Enter privileged EXEC mode and then enter the show startup-config
command to display the passwords in the configuration file:
Router> enable
Router# show startup-config
13. Scan the configuration file displayed for the passwords (the enable and
enable secret passwords are usually near the beginning of the file and the
console password is near the end of the file). An example display follows:
enable secret 5 $1$ORPP$s9syZt4uKn3SnpuLDrhuei
enable password sand
.
.
line con 0
password seashells
Proceed to step 14 to replace an enable secret, console, or enable password. If there is no enable secret password, note the enable and console
passwords, if they are not encrypted, and proceed to step 17.
Maintenance
CAUTION
Do not take the next three steps unless you have determined that you must
change or replace the enable, enable secret, or console passwords. Failure to
follow the steps as shown might cause you to erase your router configuration.
14. Enter the configure memory command to modify or replace passwords
in NVRAM:
Router# configure memory
15. Enter the configure terminal command to enter configuration mode:
Router# configure terminal
16. Change only the passwords that are necessary for your configuration.
The following example shows how to change all three types of passwords.
The first two lines show how to change the enable secret and enable
passwords. The last two lines show how to change the console password:
Router(config)# enable secret pail
Router(config)# enable password shovel
Router(config)# line con 0
Router(config-line)# password con1
For maximum security, be sure the enable secret and enable passwords
are different.

Recovering Lost Passwords
Troubleshooting
You can remove individual passwords by using the no form of these
commands. For example, enter the no enable secret command to
remove the enable secret password.
17. Configure all interfaces to be administratively up. In the following
example, the Ethernet 0 port is configured to be administratively up:
Router(config-line)# interface ethernet 0
Router(config-if)# no shutdown
Enter the equivalent commands for all interfaces that were originally
configured.
18. Set the configuration register to the original value you noted in step 3 or
the factory-default value (0x2102). The following example shows how to
set the configuration register to the factory-default value:
Do not take the next three steps unless you have changed or replaced a
password or you might erase your router configuration. If you did not change
or replace a password, proceed to step 23 and log in.
20. Enter the copy running-config startup-config command to save the
new configuration to NVRAM. This command copies the changes you just
made to the running configuration to the startup configuration. The
following message appears:
Router# copy running-config startup-config
Building configuration...
[OK]
Router#
21. Reboot the router:
Router# reload
Proceed with reload? [confirm]
22. Press Return to confirm. When the router reboots it will use the new
configuration register value you set in step 18.
23. Log in to the router with the new or recovered passwords.

Virtual Configuration Register Settings
Virtual Configuration Register Settings
The router has a 16-bit virtual configuration register, which is written into
NVRAM. You might want to change the virtual configuration register settings
for the following reasons:
■Set and display the configuration register value
■Force the system into the ROM monitor or boot ROM
■Select a boot source and default boot filename
■Enable or disable the Break function
■Control broadcast addresses
■Set the console terminal baud rate
Recover a lost password (ignore the configuration file in NVRAM)
■
■Enable TFTP server boot
Table 4-3 lists the meaning of each of the virtual configuration memory bits,
and defines the boot field names.
Maintenance
CAUTION
To avoid confusion and possibly halting the router, remember that valid
configuration register settings might be combinations of settings and not just
the individual settings listed in table 4-3. For example, the factory default value
of 0x2102 is a combination of settings.

Changing Configuration Register Settings
Take the following steps to change the configuration register while running
the Cisco IOS software:
1. Enter the enable command and your password to enter privileged mode:
Router> enable
Password:
Router#
2. Enter the
configure terminal
command at the privileged EXEC prompt
(Router#):
Router# configure terminal
3. To set the contents of the configuration register, enter the configuration
command config-registervalue, where value is a hexadecimal number
preceded by 0x (see table 4-3 and table 4-4):
config-register 0xvalue
(The virtual configuration register is stored in NVRAM.)

4. Press Ctrl-Z to exit configuration mode. The new settings will be saved
to memory; however, the new settings do not take effect until the system
software is reloaded by rebooting the router.
5. To display the configuration register value currently in effect and the value
that will be used at the next reload, enter the show version EXEC
command. The value displays on the last line of the screen display:
Configuration register is 0x142 (will be 0x102 at next reload)

6. Reboot the router. The new value takes effect. Configuration register
changes take effect only when the router restarts, which occurs when you
switch the power OFF and ON or when you enter the reload command.
Virtual Configuration Register Bit Meanings
The lowest four bits of the virtual configuration register (bits 3, 2, 1, and 0)
form the boot field. (See table 4-4.) The boot field specifies a number in binary
form. If you set the boot field value to 0, you must boot the operating system
manually by entering the b command at the bootstrap prompt, as follows:
> b [tftp] flash filename
The b command options are as follows:
■b—Boots the default system software from ROM
■
b flash—Boots the first file in Flash memory
■b filename [host]—Boots from the network using a TFTP server
■b flash [filename]—Boots the file filename from Flashmemory
For more information about the command b [tftp] flashfilename, refer to
the Cisco IOS configuration guide and command reference publications.
Maintenance
If you set the boot field value to a value of 0x2 to 0xF, and a valid system boot
command is stored in the configuration file, the router boots the system
software as directed by that value. If you set the boot field to any other bit
pattern, the router uses the resulting number to form a default boot filename
for booting from the network using a TFTP server. (See table 4-5.)
In the following example, the virtual configuration register is set to boot the
router from Flash memory and to ignore Break at the next reboot of the router:
Router> enable
password: enablepassword
Router# conf term
Enter configuration commands, one per line.
Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z
config-register 0x102
boot system flash [filename]
^Z
Router#
The router creates a default boot filename as part of the automatic configuration processes. The boot filename consists of cisco, plus the octal equivalent
of the boot field number, a hyphen, and the processor type.
A boot system configuration command in the router configuration in NVRAM
overrides the default boot filename.
4-11
Maintenance
Troubleshooting
Virtual Configuration Register Settings
Bit 8 controls the console Break key. Setting bit 8 (the factory default) causes
the processor to ignore the console Break key. Clearing bit 8 causes the
processor to interpret the Break key as a command to force the system into
the bootstrap monitor, thereby halting normal operation. A break can be sent
in the first 60 seconds while the system reboots, regardless of the configuration settings.
Bit 10 controls the host portion of the IP broadcast address. Setting bit 10
causes the processor to use all zeros; clearing bit 10 (the factory default)
causes the processor to use all ones. Bit 10 interacts with bit 14, which controls
the network and subnet portions of the broadcast address. (See table 4-6.)
Table 4-6.Configuration Register Settings for Broadcast Address Destination
Bit 13 determines the server response to a bootload failure. Setting bit 13
causes the server to load operating software from ROM after five unsuccessful
attempts to load a boot file from the network. Clearing bit 13 causes the server
to continue attempting to load a boot file from the network indefinitely. The
default setting for bit 13 is 1.

Copying a Cisco IOS Image to Flash
Memory
You may need to copy a new Cisco IOS image to Flash memory whenever a
new image or maintenance release becomes available. Use the instructions on
page 1-6 to obtain the latest version. Use the copy tftp flash command for
the copy procedure.
Take the following steps to copy a new image to Flash memory:
1. Enter the show flash command to make sure there is enough space
available before copying a file to Flash memory. Compare the size of the
file you want to copy to the amount of available Flash memory displayed.
2. Make a backup copy of the current image.
3. Enter enable mode and then enter the copy tftp flash command to copy
the new image into Flash memory:
Flash load helper vX.0
This process will accept the copy options and then terminate
the current system image to use the ROM based image for the copy.
Routing functionality will not be available during that time.
If you are logged in via telnet, this connection will terminate.
Users with console access can see the results of the copy operation.
---- ******** ---Proceed? [confirm]
4. Press Return to confirm. If there is an image already in Flash memory,
the router displays the name and size of the file. Then the router prompts
you for the IP address or name of the remote host:
Address or name of remote host [hostname]?
The remote host can be a server or another router with a valid Flash
system software image.
5. Enter the IP address or name of the remote host. The router then prompts
you for the name of the source file:
**** NOTICE ****
Maintenance
Source file name?
6. Enter the name of the source file. The following prompt displays:
Destination file name [filename]?
7. Press Return to accept the default filename or enter a different filename.

Appletalk protocols. This is because bridging forwards multicast and broadcast packets from the 100 Mbps network to the much slower T1 or ISDN lines.
This will overload the WAN link with traffic. In routing mode, the Router will
not forward multicast and broadcast packets off of the network.

Identifying a Roll-Over Cable
You can identify a roll-over cable by comparing the two modular ends of
the cable. Holding the cables side-by-side, with the tab at the back, the
wire connected to the pin on the outside of the left plug should be the same
color as the wire connected to the pin on the outside of the right plug. (See
figure A-1). If your cable came from Cisco Systems, pin 1 will be white on one
connector, and pin 8 will be white on the other (a roll-over cable reverses pins
1 and 8, 2 and 7, 3 and 6, and 4 and 5).

■If your LAN covers an area served by more than one power distribution
system, be sure their safety grounds are securely interconnected.
■LAN cables may occasionally be subject to hazardous transient voltages
(such as lightning or disturbances in the electrical utilities power grid).
Handle exposed metal components of the network with caution.
Servicing.
There are no user-serviceable parts inside these products. Any servicing,
adjustment, maintenance, or repair must be performed only by service-trained
personnel.
