Recovering Lost Passwords
Maintenance
You can remove individual passwords by using the no form of these
commands. For example, enter the no enable secret command to
remove the enable secret password.
17. Configure all interfaces to be administratively up. In the following
example, the Ethernet 0 port is configured to be administratively up:
Router(config-line)# interface ethernet 0
Router(config-if)# no shutdown
Enter the equivalent commands for all interfaces that were originally
configured.
18. Set the configuration register to the original value you noted in step 3 or
the factory-default value (0x2102). The following example shows how to
set the configuration register to the factory-default value:
Router(config-if)# config-register 0x2102
Router(config)#
19. Press Ctrl-Z to exit configuration mode.
CAUTION
Do not take the next three steps unless you have changed or replaced a
password or you might erase your router configuration. If you did not change
or replace a password, proceed to step 23 and log in.
20. Enter the copy running-config startup-config command to save the
new configuration to NVRAM. This command copies the changes you just
made to the running configuration to the startup configuration. The
following message appears:
Router# copy running-config startup-config
Building configuration...
[OK]
Router#
21. Reboot the router:
Router# reload
Proceed with reload? [confirm]
22. Press Return to confirm. When the router reboots it will use the new
configuration register value you set in step 18.
23. Log in to the router with the new or recovered passwords.
