Appendix C Troubleshooting Initial Startup Problems
Replacing or Recovering a Lost Password
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 (rommon1>).
Step 6
Set the configuration register using the configuration register utility; enter the
confreg
command at the
ROM monitor prompt as follows:
rommon1> confreg
Step 7
Answer yes to the enable
ignore system config info?
question, and note the current configuration register
settings.
Step 8
Initialize the router by entering the reset command as follows:
rommon2> reset
The router initializes, the configuration register is set to 0x142, and the router boots the system image
from flash memory and enters the System Configuration Dialog prompt as follows:
--- System Configuration Dialog --
Step 9
Enter no in response to the System Configuration Dialog prompts until the following message is
displayed:
Press RETURN to get started!
Step 10
Press Return. The user EXEC prompt is displayed as follows:
Router>
Step 11
Enter the enable command to enter privileged EXEC mode. Then 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 look something like this:
enable secret 5 $1$ORPP$s9syZt4uKn3SnpuLDrhuei
enable password 23skiddoo
.
.
line con 0
password onramp
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.
