Command Mode reset configuration.

Usage Guideline It is necessary to authenticate a user for access management. The pairing of

username and password is a basic authenticating mechanism. 'Password

Recovery' provides administrators a handle for the scenario of administrators

wanting to update password for some reason (e.g. forgetting password). For

concerns of security this feature is only applicable for direct connection to the

console port of the switch and the administrators only has 5 seconds during

which they can input a specific key (shift+6) after boot up procedure is

complete(i.e. when the username prompt or command prompt is shown).

When the specific key is inputted, user can enter reset configuration mode. In

this mode, user can use the command password-recovery to:

(1)Update the configuration for user account: update new password for existed

user or add a user account.

(2)Update the password for the administrator-privileged level: to make the user

have enough access right to manage the system.

(3)Force AAA module to switch the user authentication for console type to local

authentication in case fail to connect the remote AAA server.

A series of prompt message will guide user to complete the Password Recovery

procedure. User could answer "yes" to update the passwords or authentication

function; answer "no" to skip it.

When Password Recovery procedure is done, user could use "logout" command

to exit the reset configuration mode. After that, user could login system again

with the new password.
