H3C交换机配置DHCP中继2010年03月21日 星期日 19:02目前网络中，很少使用交换机来做DHCP server，一般都是在交换机上配置DHCP中继来完成内网的IP地址分发。拓扑环境环境说明：DHCP server链接到H3C交换机的e1/0/1端口上，并属于vlan100；pc1与H3C交换机e1/0/2互联，属于vlan2；pc2与H3C交换机e1/0/3互联，属于vlan3.交换机配置实例：H3Cdhcp-server 0 ip 172.16.0.254 指定DHCP服务器地址H3Cvlan 100H3C-vlan100port e1/0/1 将服务器端口放入vlan100H3C-vlan100quitH3Cinterface vlan-interface 100H3C-Vlan-interface100ip address 172.16.0.1 255.255.255.0H3Cvlan 2H3C-vlan2port Ethernet 1/0/2H3C-vlan2quitH3Cinterface Vlan-interface 2H3C-Vlan-interface2ip address 10.1.1.1 255.255.255.0H3C-Vlan-interface2dhcp-server 0 在vlan2中指定dhcp中继H3Cvlan 3H3C-vlan3port Ethernet 1/0/3H3C-vlan3quitH3Cinterface Vlan-interface 3H3C-Vlan-interface3ip address 10.1.2.1 255.255.255.0H3C-Vlan-interface3dhcp-server 0 在vlan3中指定dhcp中继SwitchAdhcp enable2. 创建（进入）VLAN100SwitchAvlan 1003. 将G1/1加入到VLAN100SwitchA-vlan100port GigabitEthernet 1/14. 创建（进入）VLAN接口100SwitchAinterface Vlan-interface 1005. 为VLAN接口100配置IP地址SwitchA-Vlan-interface100ip address 192.168.0.1 255.255.255.06. 创建（进入）VLAN10SwitchAvlan 107. 将E0/1-E0/10加入到VLAN10SwitchA-vlan10port Ethernet 0/1 to Ethernet 0/108. 创建（进入）VLAN接口10SwitchAinterface Vlan-interface 109. 为VLAN接口10配置IP地址SwitchA-Vlan-interface10ip address 10.10.1.1 255.255.255.010. 使能VLAN接口10的DHCP中继功能SwitchA-Vlan-interface10dhcp select relay11. 为VLAN接
