interface Vlan-interface101
description to IDC-S3026C-05-FE0/1->IDC-S6503-01-FE
ip address 192.168.2.68 255.255.255.240
1，交换机上绑定了管理IP
2，交换机必须打开了TELNET功能，就是说在交换机上开通了AAA认证中的TELNET功能
以上缺一就不能用电脑TELNETN上交换机。估计你缺少了第二条配置。追问
用什么命令查看交换机是否已经开通了AAA认证中的TELNET功能
参考技术A 如果用户要通过 Telnet、网管等方式对以太网交换机进行远程管理，则交换机上必须要设置 IP 地址，并确保用户和交换机之间路由可达。H3C系列二层以太网交换机同时只能有一个 VLAN对应的VLAN接口可以配置 IP地址，而该 VLAN即为管理 VLAN。管理vlan配置：
management-vlan vlan-id 参考技术B 登陆交换机
sys
aaa 进入aaa模式然后display this
service-type telnet 如果有这个就说明你配置了telnet
ok ？ 参考技术C 这个是路由设置吗

一、华为三层交换机s5700系列
二、实验测试拓扑
三、创建管理IP
1.进入特权模式
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
2.关闭信息中心消息提示
[Huawei]undo info-center enable
Info: Information center is disabled.
3.创建交换机管理VLAN
[Huawei]vlan 200
[Huawei-vlan200]
4.配置管理IP地址
[Huawei]vlan 200
[Huawei-vlan200]management-vlan
[Huawei-vlan200]quit
[Huawei]interface Vlanif 200
[Huawei-Vlanif200]ip address 192.168.200.254 24
[Huawei-Vlanif200]quit
[Huawei]
5.将管理接口加入到管理VLAN
[Huawei]interface GigabitEthernet 0/0/24
[Huawei-GigabitEthernet0/0/24]port link-type trunk
[Huawei-GigabitEthernet0/0/24]port trunk allow-pass vlan 200
[Huawei-GigabitEthernet0/0/24]quit
[Huawei]
四、配置telnet
1.配置telnet
[Huawei]telnet server enable #//Telnet出厂时是关闭的，需要开启
Info: The Telnet server has been enabled.
[Huawei]user-interface vty 0 4 #//Telnet常用于设备管理员登录，推荐使用AAA认证
[Huawei-ui-vty0-4]protocol inbound telnet
[Huawei-ui-vty0-4]authentication-mode aaa
[Huawei-ui-vty0-4]idle-timeout 15
[Huawei-ui-vty0-4]quit
[Huawei]aaa
[Huawei-aaa]local-user admin password cipher admin # //配置管理员Telnet登录交换机的用户名和密码。用户名不区分大小写，密码区分大小写
[Huawei-aaa]local-user admin privilege level 15 #//将管理员的账号权限设置为15（最高）
[Huawei-aaa]local-user admin service-type telnet
[Huawei-aaa]
2.测试登录telnet
<Huawei>tel
<Huawei>telnet 192.168.200.254
Trying 192.168.200.254 ...
Press CTRL+K to abort
Connected to 192.168.200.254 ...
Login authentication
Username:admin
Password:
Info: The max number of VTY users is 5, and the number
of current VTY users on line is 1.
The current login time is 2022-08-19 00:50:57.
<Huawei>
五、配置端口IP和vlan
1.配置VLAN及ip
配置业务vlan10、vlan20、vlan30
[Huawei]vlan batch 10 20 30
Info: This operation may take a few seconds. Please wait for a moment...done.
[Huawei]interface Vlanif 10
[Huawei-Vlanif10]ip address 192.168.10.1 24
[Huawei-Vlanif10]quit
[Huawei]interface Vlanif 20
[Huawei-Vlanif20]ip address 192.168.20.1 24
[Huawei-Vlanif20]quit
[Huawei]interface Vlanif 30
[Huawei-Vlanif30]ip address 192.168.30.1 24
[Huawei-Vlanif30]quit
2.将端口加入到vlan
[Huawei]port-group 1
[Huawei-port-group-1]group-member GigabitEthernet 0/0/1 to GigabitEthernet 0/0/5
[Huawei-port-group-1]port link-type trunk
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-GigabitEthernet0/0/2]port link-type trunk
[Huawei-GigabitEthernet0/0/3]port link-type trunk
[Huawei-GigabitEthernet0/0/4]port link-type trunk
[Huawei-GigabitEthernet0/0/5]port link-type trunk
[Huawei-port-group-1]port trunk allow-pass vlan 10
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
[Huawei-GigabitEthernet0/0/2]port trunk allow-pass vlan 10
[Huawei-GigabitEthernet0/0/3]port trunk allow-pass vlan 10
[Huawei-GigabitEthernet0/0/4]port trunk allow-pass vlan 10
[Huawei-GigabitEthernet0/0/5]port trunk allow-pass vlan 10
[Huawei-port-group-1]quit
[Huawei]port-gr
[Huawei]port-group 2
[Huawei-port-group-2]group-member GigabitEthernet 0/0/6 to GigabitEthernet 0/0/1
0
[Huawei-port-group-2]port link-type trunk

[Huawei-port-group-3]group-member GigabitEthernet 0/0/11 to GigabitEthernet 0/0/
15
[Huawei-port-group-3]port link-type trunk
[Huawei-GigabitEthernet0/0/11]port link-type trunk
[Huawei-GigabitEthernet0/0/12]port link-type trunk
[Huawei-GigabitEthernet0/0/13]port link-type trunk
[Huawei-GigabitEthernet0/0/14]port link-type trunk
[Huawei-GigabitEthernet0/0/15]port link-type trunk

[Huawei-GigabitEthernet0/0/14]port trunk allow-pass vlan 30
[Huawei-GigabitEthernet0/0/15]port trunk allow-pass vlan 30
[Huawei-port-group-3]quit
[Huawei]
3.配置两台交换机连接端口
[Huawei]interface GigabitEthernet 0/0/23
[Huawei-GigabitEthernet0/0/23]port link-type tr
[Huawei-GigabitEthernet0/0/23]port link-type trunk
[Huawei-GigabitEthernet0/0/23]port trunk allow-pass vlan 10 20 30
[Huawei-GigabitEthernet0/0/23]
[Huawei]interface GigabitEthernet 0/0/22
[Huawei-GigabitEthernet0/0/22]port link-type trunk all
[Huawei-GigabitEthernet0/0/22]port trunk allow-pass vlan 10 20 30
[Huawei-GigabitEthernet0/0/22]
六、SW2和SW3配置
1.SW2配置
[Huawei]vlan batch 10 20 30
[Huawei]interface GigabitEthernet 0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-port-group-link-tr]port trunk allow-pass vlan 10 20 30
[Huawei-port-group-link-tr]
[Huawei]interface Ethernet0/0/2
[Huawei-Ethernet0/0/2]port link-type access
[Huawei-Ethernet0/0/2]port default vlan 10
[Huawei-Ethernet0/0/2]
2.SW3配置
[Huawei]vlan batch 10 20 30
[Huawei]interface GigabitEthernet 0/0/1
[Huawei-port-group-link-tr]port trunk allow-pass vlan 10 20 30
[Huawei-port-group-link-tr]
[Huawei]interface Ethernet0/0/2
[Huawei-Ethernet0/0/2]port link-type access
[Huawei-Ethernet0/0/2]port default vlan 10
[Huawei-Ethernet0/0/2]
七、测试四台IP互通
八、华为hyprid接口介绍
1.华为hyprid介绍
Hybrid特性是华为交换机的专有特性，该特性为局域网的搭建提供了更多的灵活性和安全性。
2.华为三种端口区别
1.Access类型端口：只能属于1个VLAN，一般用于连接计算机端口；
2.Trunk类型端口：可以允许多个VLAN通过,可以接收和发送多个VLAN 报文,一般用于交换机与交换机相关的接口。
3.Hybrid类型端口：可以允许多个VLAN通过，可以接收和发送多个VLAN 报文，可以用于交换机的间连接也可以用于连接用户计算机。
3.hyprid模式配置SW2
[Huawei]interface Ethernet0/0/1
[Huawei-Ethernet0/0/1]dis this
#
interface Ethernet0/0/1
#
return
[Huawei-Ethernet0/0/1]pori
[Huawei-Ethernet0/0/1]port
[Huawei-Ethernet0/0/1]port lin
[Huawei-Ethernet0/0/1]port link-hy
[Huawei-Ethernet0/0/1]port link-ty
[Huawei-Ethernet0/0/1]port link-type h
[Huawei-Ethernet0/0/1]port link-type hybrid
[Huawei-Ethernet0/0/1]port h
[Huawei-Ethernet0/0/1]port hybrid un
[Huawei-Ethernet0/0/1]port hybrid untagged v
[Huawei-Ethernet0/0/1]port hybrid untagged vlan 30
[Huawei-Ethernet0/0/1]port
[Huawei-Ethernet0/0/1]port hy
[Huawei-Ethernet0/0/1]port hybrid p
[Huawei-Ethernet0/0/1]port hybrid pvid vlan 30
[Huawei-Ethernet0/0/1]quit
4.测试网络联通情况
九、使用hybrid配置trunk效果
1.更换trunk为hybird模式
[Huawei]interface GigabitEthernet 0/0/1
[Huawei-GigabitEthernet0/0/1]dis this
#
interface GigabitEthernet0/0/1
port link-type trunk
port trunk allow-pass vlan 10 20 30
#
return
[Huawei-GigabitEthernet0/0/1]undo port trunk allow-pass vlan 10 20 30
[Huawei-GigabitEthernet0/0/1]port link-type hybrid
[Huawei-GigabitEthernet0/0/1]port l
[Huawei-GigabitEthernet0/0/1]port hybrid tagged vlan 10 20 30
[Huawei-GigabitEthernet0/0/1]dis this
#
interface GigabitEthernet0/0/1
port hybrid tagged vlan 10 20 30
#
return
[Huawei-GigabitEthernet0/0/1]
2.查看网络联通情况
3.查看本征vlan
[Huawei]display port vlan
