Chapter 4 Observing System Startup and Performing a Basic Configuration Replacing or Recovering a Lost Password The enable secret password is encrypted and cannot be recovered; it must be replaced. The enable and console login passwords may be encrypted or clear text. Proceed to the next step to replace an enable secret, console login, or enable password. If there is no enable secret password, note the enable and console login passwords, if they are not encrypted, and proceed to Step 17. Caution Do not execute the next step unless you have determined you must change or replace the enable, enable secret, or console login passwords. Failure to follow the steps as shown might cause you to erase your router configuration. Step 13 Enter the configure memory command to load the startup configuration file into running memory. This action allows you to modify or replace passwords in the configuration. Router# configure memory Step 14 Enter the privileged EXEC command configure terminal to enter configuration mode: Hostname# configure terminal Step 15 Change all three passwords using the following commands: Hostname(config)# enable secret newpassword1 Hostname(config)# enable password newpassword2 Hostname(config)# line con 0 Hostname(config-line)# password newpassword3 Step 16 Change only the passwords necessary for your configuration. You can remove individual passwords by using the no form of the above commands. For example, entering the no enable secret command removes the enable secret password. You must configure all interfaces to be not administratively shut down as follows: Hostname(config)# interface fastethernet 0/0 Hostname(config-int)# no shutdown Step 17 Enter the equivalent commands for all interfaces that were originally configured. If you omit this step, all interfaces are administratively shut down and unavailable when the router is restarted. Use the config-register command to set the configuration register to the original value noted in Step 3 or Step 8, or to the factory default value 0x2102 as follows: Hostname(config)# config-register 0x2102 Step 18 Press Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration mode and return to the EXEC command interpreter. Caution Do not execute the next step unless you have changed or replaced a password. If you skipped Step 13 through Step 16, skip to Step 20. Failure to observe this caution causes you to erase your router configuration file. Step 19 Step 20 Step 21 Enter the copy running-config startup-config command to save the new configuration to NVRAM. Enter the reload command to reboot the router. Log in to the router with the new or recovered passwords. OL-5013-09 This completes the steps for recovering or replacing a lost enable, enable secret, or console login password.
