Chapter 51 Troubleshooting
Recovering from a Lost or Forgotten Password
Step 1 Elect to continue with password recovery and lose the existing configuration:
Would you like to reset the system back to the default configuration (y/n)? Y
Step 2 Load any helper files:
Switch: load_helper
Step 3 Display the contents of flash memory:
switch: dir flash:
The switch file system appears:
Directory of flash:
13 drwx 192 Mar 01 1993 22:30:48 switch_image
16128000 bytes total (10003456 bytes free)
Step 4 Boot up the system:
Switch: boot
You are prompted to start the setup program. To continue with password recovery, enter N at the prompt:
Continue with the configuration dialog? [yes/no]: N
Step 5 At the switch prompt, enter privileged EXEC mode:
Switch> enable
Step 6 Enter global configuration mode:
Switch# configure terminal
Step 7 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 8 Return to privileged EXEC mode:
Switch (config)# exit
Switch#
Note Before continuing to Step 9, power on any connected stack members and wait until they have
completely initialized.
Step 9 Write the running configuration to the startup configuration file:
Switch# copy running-config startup-config
The new password is now in the startup configuration.
Note 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.
