How to recover the lost login password of network equipment Console port

Application scenarios:

Logging into the device through the Console port is the most commonly used way to manage the equipment on the spot. Usually, for the sake of security, we will configure the login password for console. Only if the password is entered correctly can we log in to the device for configuration and management.

Treatment method:

1. The first method is to reconfigure the Console login password through other login methods, such as telnet or stelnet login devices.

two。 The second way is to clear the Console login password through the BootROM menu (this way requires rebooting the device, please choose to do it at the appropriate time).

Experimental operation:

The first method (through other login methods) steps:

If the authentication method is a password when logging in, the steps are as follows:

System-view

[HUAWEI] user-interface console 0

[HUAWEI-ui-console0] authentication-mode password

[HUAWEI-ui-console0] set authentication password cipher Huawei@123

[HUAWEI-ui-console0] return

Save

If the authentication method at login is AAA authentication, the steps are as follows:

System-view

[HUAWEI] user-interface console 0

[HUAWEI-ui-console0] authentication-mode aaa

[HUAWEI-ui-console0] quit

[HUAWEI] aaa

[HUAWEI-aaa] local-user admin123 password irreversible-cipher Huawei@123

[HUAWEI-aaa] local-user admin123 service-type terminal

[HUAWEI-aaa] return

Save

The second method (through the BootROM menu) steps:

(1) first, you need to log in to the device through Console, and then restart it with reboot. When a print message similar to "Press Ctrl+B to enter boot menu" appears in the interface, press the shortcut key "Ctrl+B" in time and enter the BootROM password to enter the BootROM main menu. (some switch models are called BootLoad menus, such as S5720HI/S12700)

The default password for BootRom is described below: in V100R006C03 and later versions, the default password is Admin@huawei.com, regardless of whether it is a box switch or a frame switch. But in previous versions of V100R006C03, the box switch was huawei and the box switch was 9300.

(2) after entering the BootROM main menu, select "Clear password for console user" to clear the Console login password.

(3) after the clearance is successful, select "Boot with default mode" to start the device under the BootROM main menu. Please note that do not select the "Reboot" option here, otherwise the password will be invalidated this time.

(4) after the system boot is completed, the system will prompt whether to configure the password for the first login. At this time, you can reset the password for the Console login. Please save the set password properly.
