Introduction to the Cisco IOS and SDM

Command-Line Interface (CLI)

I sometimes refer to the CLI as “Cash Line Interface” because, if you can create advanced

configurations on Cisco routers and switches using the CLI, then you’ll get the cash!

To use the CLI, press Enter after the router finishes booting up. After you do that, the

router will respond with messages that tell you all about the status of each and every one

of its interfaces and then display a banner and ask you to log in. Here’s an example:

-----------------------------------------------------------------------

Cisco Router and Security Device Manager (SDM) is installed on this

device. This feature requires the one-time use of the username

"cisco" with the password "cisco". The default username and password

have a privilege level of 15.

Please change these publicly known initial credentials using SDM or the

IOS CLI. Here are the Cisco IOS commands.

username <myuser> privilege 15 secret 0 <mypassword>

no username cisco

Replace <myuser> and <mypassword> with the username and password you

want to use.

For more information about SDM please follow the instructions in the

QUICK START GUIDE for your router or go to http://www.cisco.com/go/sdm
