一、实验拓扑

f04acda16878410fb343d8b481aee0a5.png

二、实验要求

三层交换机S1通过DHCP的公有地址池给PC1和PC2分配IP地址,PC1属于vlan30,PC2属于vlan40,具体要求如下:

(1) 更改主机名S1

(2) 创建vlan 30 40

(3) 配置vlanif 30接口的IP地址为192.168.30.254,vlanif 40接口的IP地址为192.168.40.254

(4) 配置access接口

(5) 启用DHCP

(6) 配置全局地址池

地址池1名:dhcp_vlan30

地址网段:192.168.30.0/24

网关:192.168.30.254

DNS服务器地址:114.114.114.114和 8.8.8.8

地址池2名:dhcp_vlan40

地址网段:192.168.40.0/24

网关:192.168.40.254

DNS服务器地址:114.114.114.114和 8.8.8.8

(7) 配置vlanif 30和vlanif40虚接口下启用全局地址池


三、实验步骤

(1) 更改主机名S1
The device is running!
<Huawei>system-view 
Enter system view, return user view with Ctrl+Z.    
[Huawei]undo info-center enable 
Info: Information center is disabled.   
[Huawei]sysname S1
[S1]

(2) 创建vlan 30 40
[S1]vlan batch 30 40
Info: This operation may take a few seconds. Please wait for a moment...done.
[S1]

(3) 配置vlanif 30接口的IP地址为192.168.30.254,vlanif 40接口的IP地址为192.168.40.254
!!!注意配置接口IP地址与配置端口access时的先后顺序,应先创建并配置vlan以及接口IP地址,再将各个端口加入相应的vlan中,否则vlan端口启动不了!!!

(8)保存S1交换机上的配置文件
[S1]q
<S1>save
The current configuration will be written to the device.
Are you sure to continue?[Y/N]y
Now saving the current configuration to the slot 0.
Save the configuration successfully.
<S1>


四、实验测试

执行ipconfig命令

执行ipconfig /release ——释放获取到的IP地址参数

执行ipconfig /renew——获取新的IP地址参数

阿里云服务器对比主机租用/托管,阿里云虚拟主机和云服务器的区别。服务器托管/租用和虚拟主机的区别,服务器托管/租用和虚拟主机的区别有: 1、服务器托管是用户独享一台服务器,而虚拟主机是多个用户共享一台服务器; 2、服务器托管用户可以自行选择操作系统,而虚拟主机用户只能选择指定范围内的操作系统;服务器托管用户可以自己设置硬盘,创造数千G以上的空间,而虚拟主机空间则相对狭小。 3、服务器托管用户可以选择防火墙以及防病毒设施,大大提高了安全性,并且服务器拥有独立IP地址,当其他站点访问量过大时或者受到攻击时不会影响我们自己的网站;虚拟主机一般情况下是共享IP的,当其中的一个站点发布违规信息、黑
