华为交换机开启Telnet服务及修改端口

1.以登录VTY0的验证方式为密码验证，密码为mf88855514为例，配置如下。
<Huawei> system-view
[Huawei] user-interface vty 0 4
[Huawei-ui-vty0-4] protocol inbound telnet
[Huawei-ui-vty0-4] authentication-mode password   //设置认证模式为密码认证
[Huawei-ui-vty0-4] set authentication password cipher mf88855514    //设置密码为：mf88855514
[Huawei-ui-vty0-4] user privilege level 3   //设置用户等级（0-15）缺省为：0
[Huawei-ui-vty0-4] return  //返回
<Huawei> save     //保存

2.以登录VTY0的验证方式为AAA授权验证，用户名为mingfeng，密码为mf88855514为例，配置如下。
<Huawei> system-view
[Huawei] user-interface vty 0 4
[Huawei-ui-vty0-4] protocol inbound telnet
[Huawei-ui-vty0-4] authentication-mode aaa  //设置认证模式为AAA认证（用户名和密码）
[Huawei-ui-vty0-4] quit
[Huawei] aaa   //进入AAA视图
[Huawei-aaa] local-user mingfeng password irreversible-cipher mf88855514   //创建用户：mingfeng 密码为：mf88855514
[Huawei-aaa] local-user mingfeng service-type telnet      //设置用户的服务类型为：Telnet
[Huawei-aaa] local-user mingfeng privilege level 3   //设置用户等级（0-15）缺省为0
Warning: This operation may affect online users, are you sure to change the user privilege level ?[Y/N]y
[Huawei-aaa] return   //返回用户视图
<Huawei> save    //保存

3.查看Telnet的端口状态

[Huawei]display telnet server status

TELNET IPV4 server :Enable

TELNET IPV6 server :Enable

TELNET server port :23

4.修改Telnet的端口

[Huawei]telnet server port 2323 //端口默认为23

[Huawei]dis telnet server status

TELNET IPV4 server :Enable

TELNET IPV6 server :Enable

TELNET server port :2323
