To learn how to use the setup command facility to configure the router, see the “Initial Configuration Using the Setup
Command Facility” section on page 19. To learn how to use the CLI to configure the router, see the “Initial Configuration
Using the CLI (Manual Configuration)” section on page 21.
Note If the rommon 1> prompt appears, your system has booted in ROM monitor mode. For information on the ROM
monitor, see the router rebooting and ROM monitor information in the Cisco IOS Configuration Fundamentals
Configuration Guide for your Cisco IOS software release.
You can access this document at the locations described in the “Where to Go Next” section on page 24.
6 Perform Initial Configuration
You can configure your router by using one of the following methods:
•Cisco Router and Security Device Manager (SDM)—If your router was purchased with a VPN bundle, SDM is installed on
the router. For instructions on configuring your router by using SDM, refer to the Cisco Router and Security Device
Manager (SDM) Quick Start Guide that shipped with your router. See the “Initial Configuration Using Cisco Router and
Security Device Manager” section on page 19 for additional information.
•Setup command facility—You can use the setup command facility to configure basic router information. After the
configuration file has been created, you can use the CLI or SDM to perform additional configuration. See the “Initial
Configuration Using the Setup Command Facility” section on page 19 for additional information.
•Command-line interface (CLI)—If you prefer to use the Cisco IOS CLI, see the “Initial Configuration Using the CLI
(Manual Configuration)” section on page 21 for instructions on how to use the CLI.
Note You need to understand how interfaces are numbered so that you know which interface you are configuring. If you need
help with interface and port numbering, see the “Interface Numbering” section on page 22.

Initial Configuration Using Cisco Router and Security Device Manager
If the following messages appear at the end of the startup sequence, Cisco Router and Security Device Manager (SDM) is
installed on your router:
yourname con0 is now available
Press RETURN to get started.
For instructions on configuring your router by using SDM, refer to the Cisco Router and Security Device Manager (SDM) Quick
Start Guide.
Tip If the messages above do not appear, SDM and the Cisco Router and Security Device Manager (SDM) Quick Start Guide
were not shipped with your router. If you want to use SDM, you can download the latest version of SDM and
instructions for installing it on your router from the following location:
http://www.cisco.com/pcgi-bin/tablebuild.pl/sdm
To obtain the SDM quick start guide, SDM release notes, and other SDM documentation, go to www.cisco.com/go/sdm
and click the Technical Documentation link.
Initial Configuration Using the Setup Command Facility
This section shows how to use the setup command facility to configure a hostname for the router, set passwords, and configure
an interface for communication with the management network. If you see the following messages at the end of the startup
sequence, the setup command facility has been invoked automatically:
--- System Configuration Dialog ---
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Would you like to enter the initial configuration dialog? [yes/no]:
The setup command facility prompts you for basic information about your router and network, and it creates an initial
configuration file.The prompts vary, depending on your router model, the installed interface modules, and the software image.
The following example and the user entries (in bold) are shown as examples only.
For interface numbering information, see the “Interface Numbering” section on page 22.
Note If you make a mistake while using the setup command facility, you can exit and run the setup command facility again.
Press Ctrl-c, and enter setup at the privileged EXEC mode prompt (3700#).
Step 1 To proceed using the setup command facility, enter yes.
Would you like to enter the initial configuration dialog? [yes/no]: yes
Step 2 When the following messages appear, press Return to enter basic management setup:
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system
Would you like to enter basic management setup? [yes/no]: yes

Step 3 Enter a hostname for the router (this example uses 3745):
Configuring global parameters:
Enter hostname [Router]: 3745
The enable secret is a password used to protect access to privileged EXEC and configuration modes. This
password, after entered, becomes encrypted in the configuration.
Step 4 Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when viewing the
configuration:
Enter enable secret: xxxx
The enable password is used when you do not specify an enable secret password, with some older software
versions, and some boot images.
Step 5 Enter an enable password that is different from the enable secret password. This password is not encrypted (less secure)
and can be seen when viewing the configuration:
Enter enable password: xxxx
The virtual terminal password is used to protect access to the router over a network interface.
Step 6 Enter the virtual terminal password, which prevents unauthenticated access to the router through ports other than the
console port:
Enter virtual terminal password: xxxx
Step 7 Respond to the following prompts as appropriate for your network:
Configure SNMP Network Management? [yes]: yes
Community string [public]:
Step 8 A summary of the available interfaces is displayed:
Note The interface numbering that appears is dependent on the type of Cisco modular router platform and on the
installed interface modules and cards.
Current interface summary
Controller Timeslots D-Channel Configurable modes Status
T1 3/0 24 23 pri/channelized Administratively up
T1 3/1 24 23 pri/channelized Administratively up
Any interface listed with OK? value "NO" does not have a valid configuration
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned NO unset up down
FastEthernet0/1 unassigned NO unset up down
Step 9 Select one of the available interfaces for connecting the router to the management network:
Enter interface name used to connect to the
management network from the above interface summary: fastethernet0/0
Step 10 Respond to the following prompts as appropriate for your network:
Configuring interface FastEthernet0/0:
Use the 100 Base-TX (RJ-45) connector? [yes]:
Operate in full-duplex mode? [no]: yes
Configure IP on this interface? [yes]:
IP address for this interface: 10.1.1.1
Subnet mask for this interface [255.0.0.0] : 255.255.0.0
Class A network is 10.0.0.0, 16 subnet bits; mask is /16
