Hello everyone,
Today I will share with you how to deal with forget the password for telnet login.
Procedure
If you forget the Telnet login password, log in to the device through the console port and set a new password for Telnet login.
# Take password authentication for VTY0 login as an example. Set the password to Huawei@123.
<Huawei> system-view
[Huawei] user-interface vty 0
[Huawei-ui-vty0] authentication-mode password
[Huawei-ui-vty0] set authentication password cipherWarning: The "password" authentication mode is not secure, and it is strongly re
commended to use "aaa" authentication mode.
Enter Password(<8-128>):
Confirm password:
[Huawei-ui-vty0] user privilege level 15
[Huawei-ui-vty0] return<Huawei> save
# Take AAA authentication for VTY0 login as an example. Set the user name and the password to admin123 and Huawei@123, respectively.
<Huawei> system-view
[Huawei] user-interface vty 0
[Huawei-ui-vty0] protocol inbound telnet
[Huawei-ui-vty0] authentication-mode aaa
[Huawei-ui-vty0] quit
[Huawei] aaa
[Huawei-aaa] local-user admin123 password irreversible-cipher Huawei@123
[Huawei-aaa] local-user admin123 service-type telnet
[Huawei-aaa] local-user admin123 privilege level 15
[Huawei-aaa] return
<Huawei> save
More Information
By default, a user only needs to pass password authentication to log in to the device from the console user interface. To prevent unauthorized users from accessing the device, change the authentication mode of the console user interface to AAA authentication.
That is all I want to share with you! Thank you!
