KB.15.15

WARNING! This means that anyone who has physical access to the switch could use this button

combination to replace the switch current configuration with the factory-default configuration, and

render the switch accessible without the need to input a username or password.

You can use the factory-reset command to prevent the Reset+Clear combination from being

used for this purpose.

Syntax:

[no]front-panel-security factory-reset

Disables or re-enables the following functions associated with using the Reset+Clear

buttons in the combination described under “Restoring the factory default

configuration” (page 43):

• Replacing the current startup-config file with the factory default

startup-config file

• Clearing any local usernames and passwords configured on the switch

Default: Both functions enabled.

For redundant management systems, this command only affects the active

management module.

NOTE: The Reset+Clear button combination always reboots the switch, regardless

of whether the [no] form of the command has been used to disable the above two

functions. Also, if you disable factory-reset, you cannot disable the

password-recovery option, and the reverse.

Figure 22 Example of disabling the factory reset option

Restoring the factory default configuration

You can also use the Reset button together with the Clear button (Reset+Clear) to restore the factory

default configuration for the switch. To do this:

1. Press and hold the Reset button.

2. While holding the Reset button, press and hold the Clear button.
