Understanding Cisco uBR10012 Router Configuration Fundamentals
The enable secret password is encrypted and cannot be recovered; it must be replaced. The enable
Note
and console passwords can be encrypted text or clear text.
Proceed to the next step to replace an enable secret, console login, or enable password. If there is no

Caution Do not perform the next step unless you have determined that you must change or replace the enable,
enable secret, or console login passwords. Failure to follow the steps as presented here could cause
your router configuration to be erased.
Enter the configure memory command to load the startup configuration file into running memory. This
Step 13
action allows you to modify or replace passwords in the configuration.
Router# configure memory
Step 14 Enter the configure terminal command for configuration mode:
Router# configure terminal
Step 15 To change all three passwords, enter the following commands:
Router(config)# enable secret newpassword1
Router(config)# enable password newpassword2
Router(config)# line con 0
Router(config)# password newpassword3
Change only the passwords necessary for your configuration. You can remove individual passwords by
using the no form of the previous commands. For example, entering the no enable secret command
removes the enable secret password.
You must configure all interfaces to not be administratively shut down as follows:
Step 16
Router(config)# interface fast ethernet 0/0/0
Router(config)# no shutdown
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
Step 17
or Step 7.
Press Ctrl-Z or type end to exit configuration mode:
Step 18
Router(config)# end
Do not perform the next step unless you have changed or replaced a password. If you have skipped

Step 13
causes the system to erase your router configuration file.
Step 19 Enter the copy running-config startup-config command to save the new configuration to nonvolatile
memory:
Router# copy running-config startup-config
Enter the reload command to reboot the router:
