+### DHCP服务器
+
+#### 一、作用
+
+1. 自动分配IP
+2. 集中管理
+3. 提高效率
+
+#### 二、基本配置步骤
+
+```
+//1. 创建DHCP地址池
+	ip dhcp pool XXXX(命名)
+//2. 配置网络地址和子网掩码
+	network 192.168.10.0 255.255.255.0
+//3. 配置默认网关
+	default-router 192.168.10.254
+//4. 配置DNS服务器
+	dns-server 8.8.8.8
+//5. 配置租约时间
+	lease 7(可选，默认1天)
+//6. 退出DHCP配置模式
+	exit
+//7. 排除不分配的IP地址范围，如网关
+	ip dhcp excluded-address 192.168.10.254
+	
+	
+//1. 查看DHCP地址池配置
+	show ip dhcp pool
+//2. 查看DHCP绑定信息
+	show ip dhcp binding
+//3. 查看DHCP冲突记录
+	show ip dhcp conflict
+//4. 清除DHCP绑定
+	clear ip dhcp binding *
+```
+
+#### 三、使用DHCP服务器
+
+```
+//配置DHCP中继(当DHCP服务器不在本地网络)
+	interface g0/0
+	ip helper-address 10.1.1.1
+```
+
