三層交換機與dhcp服務器對接?一、實驗步驟:1、在模拟器上拉出一台三層換機和三台PC,分别用線纜連接好并啟動,接下來我們就來聊聊關于三層交換機與dhcp服務器對接?以下内容大家不妨參考一二希望能幫到您!
一、實驗步驟:
1、在模拟器上拉出一台三層換機和三台PC,分别用線纜連接好并啟動。
2、PC1連接三層交換機的vlanif地址為:192.168.1.1,PC2連接三層交換機vlanif地址為:
192.168.2.1,PC3連接三層交換機的vlanif地址為:192.168.3.1。各接口地址如圖所示。
3、VLAN10和VLAN20配置DHCP服務,讓PC1和PC2自動獲取IP地址,并在VLAN10上做地址排 除,将排除地址192.168.1.220到192.168.1.254用于服務器,VLAN30手工配置IP地址。
4、先在三層交換機上配置三個VLAN——》将各PC連接的端口配置為Access模式,并劃入相應V LAN——》給相應VLAN的三層接口配置網關——》在全局模式下建地址池——》将配置好的 地址池應用在三層接口上,讓PC自動獲取IP地址
二、配置命令:
