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

At the switch prompt, enter privileged EXEC mode:

Switch> enable

Rename the configuration file to its original name:

Switch# rename flash:config.text.old flash:config.text

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.

Enter global configuration mode:

Switch# configure terminal

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.

Return to privileged EXEC mode:

Switch (config)# exit

Write the running configuration to the startup configuration file:

Switch# copy running-config startup-config

The new password is now in the startup configuration.

Reload the switch:

Switch# reload

This procedure is likely to leave your switch virtual interface in a shutdown state. You can see

which interface is in this state by entering the show running-config privileged EXEC command.

To re-enable the interface, enter the interface vlan vlan-id global configuration command, and

specify the VLAN ID of the shutdown interface. With the switch in interface configuration

mode, enter the no shutdown command.
