For More Information About SDM and About Your Router
For additional information about SDM features, refer to the SDM online help. Additional information
presentation, Flash demo, and links to technical documentation and product updates.
Refer to the Quick Start Guide for your router for other procedures, such as connecting a PC to the router
console port so that you can use the CLI when you need to, and using the router LEDs to verify
installation. The Quick Start Guide may also contain important warranty information.
I Want to Use the Cisco IOS Startup Sequence
If you have already configured the router using SDM, you don’t need to read this section.
Because SDM uses a default configuration file, your router will not execute the standard Cisco IOS
startup sequence. You can use this section to run Cisco IOS setup utility and take advantage of a TFTP
or BOOTP configuration download, or use other features available through the standard Cisco IOS
startup sequence. It also tells you what to do if you want to use SDM in the future.
SDM has created a default configuration for your router. The configuration does the following:
•
•
•
•
Provides an IP address for your Fast Ethernet interface, enabling an interface to your LAN
Enables your router’s HTTP/HTTPS server, allowing HTTP access from your LAN
Creates a default username (cisco) and password (cisco) with privilege level 15
Enables Telnet/SSM access to the router from your LAN
If you want to erase the existing configuration and take advantage of the Cisco IOS startup sequence,
perform the following steps. SDM will remain on the router.
Step 1
Step 2
Connect the light blue console cable, included with your router, from the blue console port on your router
to a serial port on your PC. Refer to your router’s Hardware Installation Guide for instructions.
Connect the power supply to your router, plug the power supply into a power outlet, and turn on your
router. Refer to your router’s Quick Start Guide for instructions.

Step 4
Use a terminal emulation program on your PC, with the terminal emulation settings of 9600 baud, 8 data
bits, no parity, 1 stop bit, and no flow control, to connect to your router.
At the prompt, enter the enable command. The default configuration file does not configure an enable
password.
yourname> enable
yourname#
Step 5
Enter the erase startup-config command.
yourname# erase startup-config
Step 6
Step 7
Confirm the command by pressing Enter.
Enter the reload command.
yourname# reload
Step 8
Confirm the command by pressing Enter.
After you press enter, the router will begin executing the standard startup sequence. If you want to be
able to use SDM to perform subsequent configurations for the router, you must use the CLI to add
statements to the configuration file. See the “I Want to Install or Enable SDM on the Router” section for
this information.
I Want to Install or Enable SDM on the Router
In order to use SDM in the future, you must configure the router to support web-based applications,
configure it with a user account defined with privilege level 15, and configure it to support the Telnet and
SSH protocols.
•
The router’s HTTP/HTTPS server must be enabled, using the following Cisco IOS commands:
ip http server
ip http secure-server
ip http authentication local
If the router uses an IPSec IOS image, the HTTPS server is enabled. Otherwise only the HTTP
server is enabled.
•
SDM requires a user account that is defined with privilege level 15 (enable privileges):
username <username> privilege 15 password 0 <password>
Note
For security purposes, the user account that you define should be different from the default
one used in the example above.
•
•
SSH/Telnet must be configured for local login and privilege level 15:
line vty 0 4
privilege level 15
login local
transport input telnet
transport input telnet ssh
Local logging should (optionally) be enabled to support the log monitoring function:
