+### Cisco路由器DHCP服务配置
+
+#### 基本配置步骤：
+
+```cisco
+! 进入全局配置模式
+Router> enable
+Router# configure terminal
+
+! 创建DHCP地址池
+Router(config)# ip dhcp pool LAN_POOL
+
+! 配置网络地址和子网掩码
+Router(dhcp-config)# network 192.168.1.0 255.255.255.0
+
+! 配置默认网关
+Router(dhcp-config)# default-router 192.168.1.1
+
+! 配置DNS服务器
+Router(dhcp-config)# dns-server 8.8.8.8
+
+! 配置租约时间（可选，默认为1天）
+Router(dhcp-config)# lease 7  [非所有版本的模拟器支持]
+
+! 退出DHCP配置模式
+Router(dhcp-config)# exit
+
+! 排除不分配的IP地址范围 ，比如网关
+Router(config)# ip dhcp excluded-address 192.168.1.100 192.168.1.254
+```
+
+###  DHCP服务验证与排错
+
+#### 验证命令：
+
+```cisco
+! 查看DHCP地址池配置
+Router# show ip dhcp pool
+
+! 查看DHCP绑定信息
+Router# show ip dhcp binding
+
+! 查看DHCP冲突记录
+Router# show ip dhcp conflict
+```
+
+#### 排错命令：
+
+```cisco
+! 清除DHCP绑定（谨慎使用）
+Router# clear ip dhcp binding *
+
+```
