如果忘记了Console口登录密码,用户可以通过以下两种方式来设置新的Console口登录密码:
在能通过telnet登录的情况下重新设置:
1. 通过STelnet/Telnet登录交换机设置新的Console口登录密码
这种方法的前提是:用户拥有STelnet/Telnet账号并且具有管理员的权限。以下涉及的命令行及回显信息以STelnet登录设备修改Console口密码为例。用户通过STelnet账号登录交换机后,请按照如下步骤进行配置。
a. 以登录用户界面的认证方式为密码认证,密码为[email protected]为例,配置如下。
[HUAWEI] user-interface console 0
[HUAWEI-ui-console0] authentication-mode password
[HUAWEI-ui-console0] set authentication password cipher [email protected]
[HUAWEI-ui-console0] return
b. 以登录用户界面的认证方式为AAA认证,用户名为admin123,密码为[email protected]为例,配置如下。
[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 [email protected]
[HUAWEI-aaa] local-user admin123 service-type terminal
[HUAWEI-aaa] return
在不能通过telnet登录的情况下通过console线更改:
通过BootROM清除Console口登录密码
交换机的BootROM提供了清除Console口登录密码的功能,用户可以在交换机启动后修改Console口登录密码,然后保存配置。请按照如下步骤进行配置。
通过Console口连接交换机,并重启交换机。当界面出现以下打印信息时,及时按下快捷键“Ctrl+B”并输入BootROM密码,进入BootROM主菜单。
框式交换机打印信息:
Press Ctrl+B to enter boot menu ... 1
Password: //输入BootROM密码 ([email protected]om)
- BIOS Menu (Version: 314)
- 1. Boot with default mode
- 2. Enter serial submenu
- 3. Enter startup submenu
- 4. Enter ethernet submenu
- 5. Enter file system submenu
- 6. Modify BOOTROM password
- 7. Clear password for console user
- 8. Config HigMem to Flash Flag
- 9. Reboot
- (Press CTRL+E to enter Diag menu)
- Enter your choice(1-9): 7
- Caution: Clear password for console user? Yes(y) or No(n): y
- Clear password for console user successfully.
- Choose "1.Boot with default mode", then set a new password by console command line.
- Caution: Do not reboot or power off the device, otherwise this operation will not take effect.
- BIOS Menu (Version: 314)
- 1. Boot with default mode
- 2. Enter serial submenu
- 3. Enter startup submenu
- 4. Enter ethernet submenu
- 5. Enter file system submenu
- 6. Modify BOOTROM password
- 7. Clear password for console user
- 8. Config HigMem to Flash Flag
- 9. Reboot
- (Press CTRL+E to enter Diag menu)
- Enter your choice(1-9): 1
记得最后一步一定要选择1 ,而不能选择9 ,因为上面选择7后明确告诉我们,如果重启则所做更改不会被保存。选择1后就可以免密码登录到命令行界面,然后就可以更改密码了
- <AC6003>sys
- [AC6003]user-interface console 0
- [AC6003-ui-console0]authentication-mode password
- [AC6003-ui-console0]set authentication password cipher

A cipher text password contains 68 characters.

到此处就更改成功了。
盒式交换机打印信息:
Press Ctrl+B or Ctrl+E to enter BootROM menu ... 2
password: //输入BootROM密码
说明:
盒式交换机的某些款型支持使用快捷键“Ctrl+E”进入BootROM主菜单,请根据设备的界面提示操作。
盒式交换机在V100R006C05之前的版本,BootROM默认密码为huawei;在V100R006C05及之后的版本,默认密码为[email protected]。
框式交换机在V100R006C00之前的版本,BootROM默认密码为9300;在V100R006C00及之后的版本,默认密码为[email protected]。
b. 在BootROM主菜单下选择“Clear password for console user”清除Console口登录密码。
c.根据交换机的提示,在BootROM主菜单下选择“Boot with default mode”启动设备。
d. 完成系统启动后,通过Console口登录时不需要认证,登录后按照系统提示配置验证密码。
e. 登录交换机后,用户可以根据需要配置Console用户界面的认证方式及密码。
