How to Recover the Telnet Login Password



How to recover the console port password on Huawei s7700 and s9700 switches? Below is the methods.

You can use Telnet to remotely maintain and manage a device. If you forget the Telnet login password, log in to the device using other methods (such as the Console interface) and set a new password.
l AAA authentication: To log in to the device, you must have a user name and a password.
l Password authentication: To log in to the device, you must have a password.
In this example, the configurations for VTY0 to VTY4 are the same.

Configuring AAA Authentication
If the user remembers the original login user name, a new password can be configured. For example, if the user name is huawei, configure a new password huawei@123 and set the user level to level 2.
<HUAWEI> system-view
[HUAWEI] user-interface vty 0 4
[HUAWEI-ui-vty0-4] authentication-mode aaa
[HUAWEI-ui-vty0-4] quit
[HUAWEI] aaa
[HUAWEI-aaa] local-user huawei password irreversible-cipher huawei@123
[HUAWEI-aaa] local-user huawei service-type telnet
[HUAWEI-aaa] local-user huawei privilege level 2
After the configuration is complete, you can use the user name huawei and password
huawei@123 to log in to the device.
If the user forgets the original login user name, configure a new user named huawei and password huawei@123 using the same method.

Configuring Password Authentication
Password authentication is configured for VTYs 0-4. Configure a password huawei@123.
<HUAWEI> system-view
[HUAWEI] user-interface vty 0 4
[HUAWEI-ui-vty0-4] authentication-mode password
[HUAWEI-ui-vty0-4] set authentication password cipher huawei@123
[HUAWEI-ui-vty0-4] return
After the configuration is complete, you can use the password huawei@123 to log in to the device.
NOTE
After you log in to the device through the VTY0 to 4, run the display current-configuration configuration user-interface command to view the authentication mode of the VTY user.

 Apply to the huawei S7700 switch, especially for the Huawei S7703 and Huawei S7706

How to Recover the Console Port Password



How to recover the console port password on Huawei s7700 and s9700 switches? Here we will tell you three methods to recover the password.

Three methods are provided to recover the console port password.
l Method 1: Log in to the device using Telnet and change the console port password.
l Method 2: Clear the console login password in BootROM and change the console port
password.
l Method 3: Clear the startup configuration file in BootROM, start the device with no configuration, and change the console port password.

NOTE
1. Method 1 is recommended. If you forget the Telnet password, use method 2 or 3.
2. If console port login uses password authentication and method 1 cannot be used, method 2 is recommended.
3. If the console port login uses AAA authentication, method 3 is recommended.
