Chapter 32 Troubleshooting
Step 4 When the boot loader prompts you, enter the break key.
This example shows the messages that appear on the console after the user enters a break key:
The system has been interrupted prior to initializing the flash file system.
The following commands will initialize the flash file system, and finish loading the
operating system software:
flash_init
load_helper
boot
After the message appears, the boot loader prompt resumes.
On the Catalyst 2955C-12 and Catalyst 2955S-12 switches, the port 13 LED blinks green, and the
port 14 LED is off during the initial appearance of the boot loader prompt. On the Catalyst 2955T-12
switch, the port 1 LED blinks green, and the port 2 LED is off during the initial appearance of the boot
loader prompt.
Initialize the flash file system:
Step 5
switch# flash_init
If you set the console port speed to anything other than 9600, it has been reset to that particular speed.
Step 6
Change the emulation software line speed to match that of the switch console port.
Load any helper files:
Step 7
switch# load_helper
Display the contents of flash memory as in this example:
Step 8
switch# dir flash:
Directory of flash:/
The switch file system appears in the directory.
Rename the configuration file to config.text.old.
Step 9
This file contains the password definition.
switch# rename flash:config.text flash:config.text.old
Step 10 Boot the system:
switch# boot
You are prompted to start the setup program. Enter N at the prompt:
Continue with the configuration dialog? [yes/no]: N
Step 11 At the switch prompt, change to privileged EXEC mode:
switch> enable
Rename the configuration file to its original name:
Step 12
switch# rename flash:config.text.old flash:config.text
Copy the configuration file into memory:
Step 13
switch# copy flash:config.text system:running-config
Source filename [config.text]?
Destination filename [running-config]?
Press Return in response to the confirmation prompts.
The configuration file is now reloaded, and you can use these normal commands to change the password.
