When you forget password

Master Password: w,lXlma

When you forget the user password or the administrator password after logout, you can use a master password to login from a serial console. The master password is only way to login to the Yamaha router without proper passwords.

Master password can be used only from the serial console, and it is necessary that the second parameter of the 'security class' command is configured as 'on', which is an initial value of that command. Using the master password, you can login as the administrator level user directly, and you can change the login password and the administrator password.
