Check the Running Configuration Settings

To check the value of the settings you have entered, enter the show running-configcommand at the Router# prompt:

Router# show running-config

To review changes you make to the configuration, use the EXEC mode show startup-configcommand to display the information stored in NVRAM.

View Your System Configuration

You can use the show version (or show hardware) and the show diag commands to display the system hardware, the software version, the names and sources of configuration files, and the boot images. Use the show diag command to determine what type of port adapter is installed.

For specific information on the show version, show diag, and other commands, refer to the modular configuration and modular command reference publications in the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware.

Perform Complex Configurations

After you have installed your Cisco 7401ASR router hardware and minimally configured the system, you might need to perform more complex configurations, which are beyond the scope of this publication.

For specific information on system and interface configuration, refer to the modular configuration and modular command reference publications in the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware. These publications contain additional information on using the configure command.

Replace or Recover a Lost Password

See the Cisco 7401ASR Installation and Configuration Guide, Chapter 3, “Starting and Configuring” for instructions. It is possible to recover the enable or console login password. The enable secret password is encrypted and must be replaced with a new enable secret password.

Troubleshooting Information

For system start-up troubleshooting information, see the online Cisco 7401ASR Installation and Configuration Guide at http://www.cisco.com/univercd/cc/td/doc/product/core/7401/7401icg/index.htm.
