eNSP_DHCP配置

一、拓扑图网络拓扑需包含以下元素PC1DHCP客户端路由器含DHCP服务功能连接线路确保接口对应关系正确二、基础配置PC1配置启用DHCP获取IP地址路由器配置配置路由器接口IP并启用DHCPHuaweisysEnter system view, return user view with CtrlZ.[Huawei]un[Huawei]undo inf[Huawei]undo info-center e[Huawei]undo info-center enableInfo: Information center is disabled.[Huawei]sysna[Huawei]sysname^Error:Incomplete command found at ^ position.[Huawei][Huawei]sysname Router配置路由器接口的ip[Router]int g 0/0/0[Router-GigabitEthernet0/0/0]ip a[Router-GigabitEthernet0/0/0]ip add[Router-GigabitEthernet0/0/0]ip address 10.1.1.1 24[Router-GigabitEthernet0/0/0]三、DHCP配置方式一接口配置[Router]dhcp enableInfo: The operation may take a few seconds.
