Step 5 Rename the configuration file to config.text.old.
This file contains the password definition.
switch: rename flash:config.text flash:config.text.old
Step 6 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 7 At the switch prompt, enter privileged EXEC mode:
Switch> enable
Step 8 Rename the configuration file to its original name:
Switch# rename flash:config.text.old flash:config.text
Note Before continuing to Step 9, power on any connected stack members and wait until they have
completely initialized. Failure to follow this step can result in a lost configuration depending on
how your switch is set up.
Step 9 Copy the configuration file into memory:
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 change the password.
Step 10 Enter global configuration mode:
Switch# configure terminal
Step 11 Change the password:
Switch (config)# enable secret password
The secret password can be from 1 to 25 alphanumeric characters, can start with a number, is case
sensitive, and allows spaces but ignores leading spaces.
Step 12 Return to privileged EXEC mode:
Switch (config)# exit
Switch#
Step 13 Write the running configuration to the startup configuration file:
Switch# copy running-config startup-config
The new password is now in the startup configuration.
