华为S系列交换机配置用户认证方式失败的解决方法

执行命令authentication-mode password配置认证方式为password认证时,出现如下错误提示信息:

Error: Failed to set user interface authentication mode. Please modify the protocol first.
设备在V200R006及之前版本缺省使用的协议为Telnet协议,在V200R007及之后版本缺省使用的协议为SSH协议。由于SSH协议仅支持AAA认证方式,因此系统缺省使用SSH协议的情况下,配置认证方式为password认证时,系统会提示错误。

此时可以在用户界面视图下,执行protocol inbound { telnet | all },配置VTY用户界面所支持的协议为Telnet协议,具体配置如下:

<HUAWEI> system-view
[HUAWEI] user-interface vty 0
[HUAWEI-ui-vty0] protocol inbound all
[HUAWEI-ui-vty0] authentication-mode password
Warning: The “password” authentication mode is not secure, and it is strongly re
commended to use “aaa” authentication mode.
[HUAWEI-ui-vty0] set authentication password cipher helloworld@6789
Warning: The “password” authentication mode is not secure, and it is strongly re
commended to use “aaa” authentication mode.
