如何用java web做网站seo运营推广
思科设备参考：DHCP自动获取IP地址实验（思科）
一，实验目的
路由器搭载DHCP，让PC通过DHCP自动获取IP地址
二，不划分vlan--全局地址池
实验拓扑
配置命令
Router
<Huawei>system-view
[Huawei]ip pool mypool
[Huawei-ip-pool-mypool]network 192.168.10.0
[Huawei-ip-pool-mypool]excluded-ip-address 192.168.10.10 192.168.10.254
[Huawei-ip-pool-mypool]lease day 2 hour 0 minute 0
[Huawei-ip-pool-mypool]dns-list 114.114.114.114
[Huawei-ip-pool-mypool]quit
[Huawei]dhcp enable
[Huawei]int g0/0/0
[Huawei-GigabitEthernet0/0/0]ip address 192.168.10.254 24
[Huawei-GigabitEthernet0/0/0]dhcp select global
[Huawei-GigabitEthernet0/0/0]quit
[Huawei]display current-configuration
测试结果
PC1 和 PC2 成功获取到 IP 地址
① 打开PC--->基础配置--->IPv4配置--->DHCP--->应用
② 命令行--->输入指令 ipconfig /renew
三，划分vlan--接口地址池
实验拓扑
配置命令
Switch

测试结果
四台 PC 都能成功获取到 IP 地址
