Chapter 2 Configuring the Cable Modem Termination System for the First Time
Understanding Cisco uBR10012 Router Configuration Fundamentals
Replacing or Recovering Passwords
Complete the following steps to recover or replace a lost enable, enable secret, or console login
password:
Step 1
Attach an ASCII terminal to the console port on your Cisco uBR10012 router.
Step 2
Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 2 stop bits.
Step 3
If you can log in to the router as a nonprivileged user, enter the
show version
command to display the
existing configuration register value. Note the value for later use. If you cannot log in to the router at all,
continue with the next step.
Step 4
Press the
Break
key or send a Break from the console terminal.
•
If Break is enabled, the router enters the ROM monitor, indicated by the ROM monitor prompt
(
rommon n>
), where
n
is the number of the command line. Proceed to Step 6.
•
If Break is disabled, power cycle the router (turn the router off or unplug the power cord, and then
restore power). Proceed to Step 5.
Step 5
Within 60 seconds of restoring the power to the router, press the
Break
key or send a Break. This action
causes the router to enter the ROM monitor and display the ROM monitor prompt (
rommon 1>
).
Step 6
To set the configuration register on a Cisco uBR10012 router, use the configuration register utility by
entering the
confreg
command at the ROM monitor prompt as follows:
rommon 1>
confreg
Answer
yes
to the enable
ignore system config info?
prompt and note the current configuration
register settings.
Step 7
Initialize the router by entering the
reset
command as follows:
rommon 2>
reset
The router initializes, the configuration register is set to 0x142, the router boots the system image from
Flash memory and enters the System Configuration dialog (setup), as follows:
--- System Configuration Dialog --
Step 8
Enter
no
in response to the System Configuration dialog prompts until the following message appears:
Press RETURN to get started!
Step 9
Press
Return.
The user EXEC prompt appears as follows:
Router>
Step 10
Enter the
enable
command to enter privileged EXEC mode.
Step 11
Enter the
show startup-config
command to display the passwords in the configuration file as follows:
Router#
show startup-config
Step 12
Scan the configuration file display looking for the passwords; the enable passwords are usually near the
beginning of the file, and the console login or user EXEC password is near the end. The passwords
displayed will look something like this:
enable secret 5 $1$ORPP$s9syZt4uKn3SnpuLDrhuei
enable password 23skiddoo
.
.
line con 0
password onramp
