No response from the serial port

If the serial port does not respond, verify that the serial cable is in good condition and the serial port

settings are correct.

Password loss

User password loss

If you lose your password, you cannot enter the system. In this case, you can boot the system by

ignoring the system configuration.

To solve the user password loss:

1. Enter the main BootWare menu, and select 6 to boot the system by ignoring the system

configuration.

The system prompts the following:

Flag Set Success.

The output shows that the setting succeeded.

2. When the main BootWare menu appears again, and select 0 to reboot the system.

System is rebooting now.

System start booting...

Booting Normal Extend BootWare....

3. Set a new password in system view after the system reboots. The console port uses password

authentication, and the password is set to 123456 and stored in plain text.

<Sysname> system-view

[Sysname] user-interface console 0

[Sysname-ui-console0] authentication-mode password

[Sysname-ui-console0] set authentication password simple 123456

When you set the password by using the set authentication password { cipher | simple }

password command, note the following:

{ If you specify the cipher keyword, the password is stored in cipher text. You cannot view the

password by using the display current-configuration command.

{ If you specify the simple keyword, the password is stored in plain text. You can use the

display current-configuration command to view the password in the current configuration.

4. After modifying the user password, save it by executing the save command. H3C recommends

saving the modifications as the default configuration file.

[Sysname] save

After reboot, the system uses the initial default configuration, but keeps the original configuration file

in storage. You can restore the original configuration by using the display saved-configuration

command to display the configuration, and then copying and executing the configuration.

Super password loss

The super password provides access to four super levels, enabling you to perform higher-level

operations.

To recover from super password loss:

1 2 ... 24 25 26 27 28 29 30 31 32 33 34 ... 41 42
