+- 配置命令
+
+  ```C#
+  int f0/1  //进去端口模式
+  swi mode access  //访问模式access
+  swi port-security   //启用接口安全模式
+  swi port-security maximum  //设置最大允许终端电脑数量
+  swi port-security violation shutdown  //设置超过最大连接数当违规设备处理关闭
+  swi port-security mac-address sticky  //绑定正确的物理地址
+  ```
+
+- 如果违规安全设置，将如何开启
+
+  ```c#
+  int f0/1  //进入端口
+  shutdown  //关闭端口
+  no shutdown  //开启端口
+  ```
+
+- 清除安全设置
+
+  ```c#
+  clear port-security sticky
+  ```
+
+- 如何测试是否生效
+
+  - 要让交换机记录到正确的MAC地址，需要在PC端ping IP地址
+
+- 查看安全配置
+
+  ```c#
+  show port-security 
+  ```
+
+- 查看端口的安全配置
+
+  ```c#
+  show port-security int f0/1
+  //如果port-security为Enabled，那说明是已启用
