H3C交换机的基本配置

#1.基本配置
```
<H3C> //用户直行模式提示符,用户视图
<H3C>system-view //进入配置视图
[H3C] sysname xxx //设置主机名成为xxx这里使用修改特权用户密码
```
#2.用户配置
```
<H3C>system-view
[H3C]super passwordH3C //设置用户分级密码
[H3C]undo superpassword //删除用户分级密码
[H3C]localuser bigheap 1234561 //Web网管用户设置,1（缺省）为管理级用户,缺省admin,admin
[H3C]undo localuserbigheap //删除Web网管用户
[H3C]user-interface aux0 //只支持0
[H3C-Aux]idle-timeout 250 //设置超时为2分50秒,若为0则表示不超时,默认为5分钟
[H3C-Aux]undoidle-timeout //恢复默认值
[H3C]user-interface vty0 //只支持0和1
[H3C-vty]idle-timeout 250 //设置超时为2分50秒,若为0则表示不超时,默认为5分钟
[H3C-vty]undoidle-timeout //恢复默认值
[H3C-vty]set authentication password123456 //设置telnet密码,必须设置
[H3C-vty]undo set authenticationpassword //取消密码
[H3C]displayusers //显示用户
[H3C]displayuser-interface //用户界面状态
```
#3.VLAN配置
```
[H3C]vlan 2 //创建VLAN2
[H3C]undo vlanall //删除除缺省VLAN外的所有VLAN,缺省VLAN不能被删除
[H3C-vlan2]port Ethernet 0/4 to Ethernet0/7 //将4到7号端口加入到VLAN2中,此命令只能用来加access端口,不能用来增加trunk或者hybrid端口
[H3C-vlan2]port-isolateenable //打开VLAN内端口隔离特性,不能二层转发,默认不启用该功能
[H3C-Ethernet0/4]port-isolate uplink-portvlan 2 //设置4为VLAN2的隔离上行端口,用于转发二层数据,只能配置一个上行端口,若为trunk,则建议允许所有VLAN通过,隔离不能与汇聚同时配置
[H3C]display vlanall //显示所有VLAN的详细信息
S1550E支持基于端口的VLAN,通过创建不同的user-group来实现,一个端口可以属于多个user-group,不属于同一个user-group的端口不能互相通信
[H3C]user-group20 //创建user-group 20,默认只存在user-group 1
[H3C-UserGroup20]port Ethernet 0/4 toEthernet 0/7 //将4到7号端口加入到VLAN20中,初始时都属于user-group 1中

```
#4.交换机IP配置
```
[H3C]vlan 20 //创建vlan

[H3C-Vlan-interface20]undo ip addressdhcp-alloc // 取消
[H3C]display dhcp //显示DHCP客户信息
<H3C>debuggingdhcp-alloc //开启DHCP调试功能
<H3C>undo debugging dhcp-alloc
```
#6.端口配置
```
[H3C]interface Ethernet0/3 //进入端口

```
#7.集群配置

S2100只能作为成员交换机加入集群中,加入后系统名改为"集群名_成员编号.原系统名"的格式.
即插即用功能通过两个功能实现: 集群管理协议MAC组播地址协商和管理VLAN协商
```

[DeviceA-vlan30] port gigabitethernet 1/0/1 to gigabitethernet 1/0/10
[DeviceA-vlan30] quit

创建Vlan-interface 30，并配置其IP地址为193.169.100.1/27
[DeviceA] interface Vlan-interface 30
[DeviceA-Vlan-interface30] ip address 193.169.100.1 27
[DeviceA-Vlan-interface30] quit
```
**创建VLAN 62，并将GigabitEthernet 1/0/11加入VLAN 62**
```
[DeviceA] vlan 62
[DeviceA-vlan62] port gigabitethernet 1/0/11
[DeviceA-vlan62] quit

创建Vlan-interface 62，并配置其IP地址为193.169.100.33/27
[DeviceA] interface Vlan-interface 62
[DeviceA-Vlan-interface62] ip address 193.169.100.33 27
[DeviceA-Vlan-interface62] quit
```
**创建VLAN 94，并将GigabitEthernet 1/0/11加入VLAN 94**
```
[DeviceA] vlan 94
[DeviceA-vlan94] port gigabitethernet 1/0/12
[DeviceA-vlan94] quit

创建Vlan-interface 94，并配置其IP地址为193.169.100.65/27
[DeviceA] interface Vlan-interface 94
[DeviceA-Vlan-interface94] ip address 193.169.100.65 27
[DeviceA-Vlan-interface94] quit
```
**创建VLAN 126，并将GigabitEthernet 1/0/11加入VLAN 126**
```
[DeviceA] vlan 126
[DeviceA-vlan126] port gigabitethernet 1/0/13
[DeviceA-vlan126] quit

创建Vlan-interface 126，并配置其IP地址为193.169.100.97/27
[DeviceA] interface Vlan-interface 126
[DeviceA-Vlan-interface126] ip address 193.169.100.97 27
[DeviceA-Vlan-interface126] quit
```
**创建VLAN 158，并将GigabitEthernet 1/0/11加入VLAN 158**
```
[DeviceA] vlan 158
[DeviceA-vlan158] port gigabitethernet 1/0/14
[DeviceA-vlan158] quit

创建Vlan-interface 158，并配置其IP地址为193.169.100.129/27
[DeviceA] interface Vlan-interface 158
[DeviceA-Vlan-interface158] ip address 193.169.100.129 27
[DeviceA-Vlan-interface158] quit
```
**创建VLAN 192
```
[DeviceA] vlan 192

创建Vlan-interface 192，并配置其IP地址为192.168.100.0/24

[DeviceA-Vlan-interface192] ip address 192.168.100.0 24
[DeviceA-Vlan-interface192] quit
```
为了使Device A上VLAN  30 62  94 126 158的报文能发送给Device B，将GigabitEthernet 1/0/48的链路类型配置为Trunk，并允许VLAN  30 62  94 126 158的报文通过，取消允许VLAN 1通过。
```
[DeviceA] interface gigabitethernet 1/0/48
[DeviceA-GigabitEthernet1/0/48] port link-type trunk
[DeviceA-GigabitEthernet1/0/48] port trunk permit vlan 30 62  94 126 158 192
[DeviceA-GigabitEthernet1/0/48] undo port trunk permit vlan 1
[DeviceA-GigabitEthernet1/0/48] quit

关闭STP
```
[DeviceB] undo stp global enable
```
2.配置Device B
创建VLAN 192，并将GigabitEthernet 1/0/1到12加入VLAN 192。

[DeviceB-GigabitEthernet1/0/48] undo port trunk permit vlan 1
[DeviceB-GigabitEthernet1/0/48] quit
```
```
创建VLAN
[DeviceB]  vlan batch  30 62 94  126  158  192
````
关闭STP
```
[DeviceB] undo stp global enable
```
