Using Recovery Procedures
Step 3
Display the contents of Flash memory:
switch: dir flash:
The switch file system is displayed:
Directory of flash:
13 drwx 192 Mar 01 1993 22:30:48 c3550-i5q3l2-mz-121-0.0.53
17 -rwx 27 Mar 01 1993 22:30:57 env_vars
5 -rwx 90 Mar 01 1993 22:30:57 system_env_vars
16128000 bytes total (10003456 bytes free)
Step 4
Boot 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#
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.
Step 10
You must now reconfigure the switch. If the system administrator has the backup switch and VLAN
configuration files available, you should use those.
