不同vlan通过DHCP中继方式获取IP的配置方法

1. 规划拓扑及VLAN，IP

2. Windows server DHCP服务器配链接描述

注意：如果在域环境下部署DHCP，在安装完成后需要使用活动目录服务器授权DHCP服务

3. 接入交换机配置（2个配置相同）

system-viewvlan batch 10 20 #新建VLANinterface GigabitEthernet0/0/1 #进入接口GigabitEthernet0/0/1 port link-type access #设置端口模式Access，vlan10port default vlan 10interface GigabitEthernet0/0/2 #进入接口GigabitEthernet0/0/2port link-type access #设置端口模式Access，vlan20port default vlan 20interface GigabitEthernet0/0/3 #进入接口GigabitEthernet0/0/3（上行端口）port link-type trunk #设置端口模式Trunk，所有vlan均可通过port trunk allow-pass vlan all

4. 核心交换机配置

system-viewvlan batch 10 20 30 40 #新建vlan10 20 30 40#配置虚拟端口地址（网关地址）interface vlan 10ip address 192.168.10.1 24interface vlan 20ip address 192.168.20.1 24interface vlan 30ip address 192.168.90.1 24interface GigabitEthernet0/0/1 #配置下行端口trunkport link-type trunk port trunk allow-pass vlan all interface GigabitEthernet0/0/2 #配置下行端口trunkport link-type trunk port trunk allow-pass vlan all interface GigabitEthernet0/0/3 #配置连接dhcp端口vlan30port link-type accessport default vlan 30#配置中继：system-viewdhcp enableinterface vlan 10dhcp select relaydhcp relay server-ip 192.168.90.9interface vlan 20dhcp select relaydhcp relay server-ip 192.168.90.9
