【DHCP实验】使用三层交换机配置DHCP Server服务器（基于全局地址池配置）
实验 使用三层交换机配置DHCP Server服务器（基于全局地址池配置）实验目录实验 使用三层交换机配置DHCP Server服务器（基于全局地址池配置）一、实验拓扑二、实验要求三、实验步骤四、实验测试一、实验拓扑 实验拓扑图二、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、实验步骤代码语言：javascript复制(1) 更改主机名S1 The device is running! 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！！！ [S1]interface Vlanif 30 [S1-Vlanif30]ip address 192.168.30.254 24 [S1-Vlanif30]display this # interface Vlanif30 ip address 192.168.30.254 255.255.255.0 # return [S1-Vlanif30]quit [S1]interface Vlanif 40 [S1-Vlanif40]ip address 192.168.40.254 24 [S1-Vlanif40]display this # interface Vlanif40 ip address 192.168.40.254 255.255.255.0 # return [S1-Vlanif40]quit [S1]display ip interface brief *down: administratively down ^down: standby (l): loopback (s): spoofing The number of interface that is UP in Physical is 2 The number of interface that is DOWN in Physical is 3 The number of interface that is UP in Protocol is 1 The number of interface that is DOWN in Protocol is 4 Interface IP Address/Mask Physical Protocol MEth0/0/1 unassigned down down NULL0 unassigned up up(s) Vlanif1 unassigned up down Vlanif30 192.168.30.254/24 down down Vlanif40 192.168.40.254/24 down down [S1] (4) 配置access接口 [S1]interface GigabitEthernet 0/0/1 [S1-GigabitEthernet0/0/1]port link-type access [S1-GigabitEthernet0/0/1]port default vlan 30 [S1-GigabitEthernet0/0/1]display this # interface GigabitEthernet0/0/1 port link-type access port default vlan 30 # return [S1-GigabitEthernet0/0/1]quit [S1]interface GigabitEthernet 0/0/3 [S1-GigabitEthernet0/0/3]port link-type access [S1-GigabitEthernet0/0/3]port default vlan 40 [S1-GigabitEthernet0/0/3]display this # interface GigabitEthernet0/0/3 port link-type access port default vlan 40 # return [S1-GigabitEthernet0/0/3]quit [S1]display ip interface brief *down: administratively down ^down: standby (l): loopback (s): spoofing The number of interface that is UP in Physical is 3 The number of interface that is DOWN in Physical is 2 The number of interface that is UP in Protocol is 3 The number of interface that is DOWN in Protocol is 2 Interface IP Address/Mask Physical Protocol MEth0/0/1 unassigned down down NULL0 unassigned up up(s) Vlanif1 unassigned down down Vlanif30 192.168.30.254/24 up up Vlanif40 192.168.40.254/24 up up [S1] (5) 启用DHCP [S1]dhcp enable [S1] (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 [S1]ip pool dhcp_vlan30 Info:It's successful to create an IP address pool.
