Chapter 2 Configuring the Cisco CMTS for the First Time
Understanding Configuration Fundamentals
Caution Do not perform 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 presented here could cause your router
configuration to be erased.
Step 12 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 13 Enter the configure terminal command for configuration mode:
Router# configure terminal
Step 14 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, enter the no enable secret command to
remove the enable secret password.
Step 15 You must configure all interfaces to be not administratively shut down as follows:
Router(config)# interface fast ethernet 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.
Step 16 Use the config-register command to set the configuration register to the original value noted in Step 3
or Step 7.
Step 17 Press Ctrl-z or type end to exit configuration mode:
Router(config)# end
Caution Do not perform the next step unless you have changed or replaced a password. If you have skipped
Step 12 through Step 15 previously, then proceed now to Step 19. Failure to observe this sequence
causes the system to erase your router configuration file.
Step 18 Enter the copy running-config startup-config command to save the new configuration to nonvolatile
memory:
Router# copy running-config startup-config
Step 19 Enter the reload command to reboot the router:
Router# reload
Step 20 Log in to the router with the new or recovered passwords.
