Viewing the Default Configuration
When you first boot up your Cisco router, some basic configuration has already been performed. All of
the LAN and WAN interfaces have been created, console and VTY ports are configured, and the inside
interface for Network Address Translation has been assigned. Use the showrunning-config command
to view the initial configuration, as shown in Example1-1.
Note If you are unable to view the initial configuration and you get a No Password Set error message, you
must reset the initial password. For details, see the “Recovering a Lost Password” section in Chapter14,
“Troubleshooting”.
