CCNA Exploration LAN Switching and Wireless: Basic Switch Concepts and Configuration Lab 2.5.3 Managing IOS and Configuration Files Would you like to reset the system back to the default configuration (y/n)? Caution Returning the switch to the default configuration results in the loss of all existing configurations. We recommend that you contact your system administrator to verify if there are backup switch and VLAN configuration files. If you enter n (no), the normal boot process continues as if the Mode button had not been pressed; you cannot access the boot loader prompt, and you cannot enter a new password. You see the message: Press Enter to continue ........ If you enter y (yes), the configuration file in flash memory and the VLAN database file are deleted. When the default configuration loads, you can reset the password. Step 1 Elect to continue with password recovery and lose the existing configuration: Would you like to reset the system back to the default configuration (y/n)? Y Step 2 Load any helper files: Switch : load_helper Step 3 Display the contents of flash memory: switch : dir flash: The switch file system appears: Directory of flash: 13 drwx 192 Mar 01 1993 22:30:48 c2960-lanbase- mz.122-25.FX.0 16128000 bytes total (10003456 bytes free) Step 4 Boot the system: Switch: boot All contents are Copyright © 1992–2007 Cisco Systems, Inc.

CCNA Exploration LAN Switching and Wireless: Basic Switch Concepts and Configuration Lab 2.5.3 Managing IOS and Configuration Files You are prompted to start the setup program. To continue with password recovery, enter N at the prompt: Continue with the configuration dialog? [yes/no]: N Step 5 At the switch prompt, enter privileged EXEC mode: Switch> enable Step 6 Enter global configuration mode: Switch# configure terminal Step 7 Change the password: Switch (config)# enable secret password The secret password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, and allows spaces but ignores leading spaces. Step 8 Return to privileged EXEC mode: Switch (config)# exit Switch# Step 9 Write the running configuration to the startup configuration file: Switch# copy running-config startup-config The new password is now in the startup configuration. Note This procedure is likely to leave your switch virtual interface in a shutdown state. You can see which interface is in this state by entering the show running-config privileged EXEC command. To re-enable the interface, enter the interface vlan vlan-id global configuration command, and specify the VLAN ID of the shutdown interface. With the switch in interface configuration mode, enter the no shutdown command.
