I tried to disable the username and password prompt of Catalyst switch C3524 by pressing the button at the port panel and then relaese during startup. It appers a switch: but I cannot find any way to skip the username and password.
Any advise? Thanks!
You can delete the file from within the privileged EXEC mode using the command delete flash:config.old - please be sure that you really do not need the file anymore as it cannot be recovered once it is deleted.
If you want to perform the so-called password recovery procedure, then in the switch: prompt, issue these commands:
load_helper ! This command may not be recognized - no problem with that
rename flash:config.text flash:config.old
Your switch will boot essentially without configuration. You will find the old startup-config stored as the file flash:config.old - you may then activate it using the command copy flash:config.old running-config or configure replace flash:config.old (the second command may not be supported) and then use the configuration mode to set up new passwords. Do not forget to save your configuration after these steps.
