配置在交换机的动态主机配置协议(DHCP)受信接口设置
客观
监听的动态主机配置协议(DHCP)提供安全机制防止收到错误DHCP响应信息包和记录DHCP地址。它通过对待在设备的端口执行此如委托或不信任。
被连接到DHCP服务器和允许分配DHCP地址的一个可信的端口是端口。在可信的端口收到的DHCP消息允许穿过设备。自动地转发自这些端口的信息包。如果监听的DHCP不是启用的，默认情况下所有端口委托。
没有允许分配DHCP地址的一个不信任的端口是端口。默认情况下，所有端口被认为不信任，直到您宣称他们在Settings页的接口委托。
此条款打算显示您如何配置DHCP在您的交换机的受信接口设置。

配置DHCP受信接口设置
Note:您的交换机基于Web的工具外观可能根据您的设备确切的模型变化。下面的镜像从SG350X-48MP被采取。
步骤1.访问您的交换机基于Web的工具并且选择IP Configuration> IPv4管理和接口。
步骤2.选择DHCP监听/中继> DHCP监听的委托的接口。
第 3 步：在委托的接口表下，请点击端口或您要然后配置的接口点击编辑。
Note:在本例中，端口GE41被选择。
第 4 步：在Settings窗口编辑的接口，请验证选择的端口在接口地区是您在上一步选择了的那个。否则，请点击下拉箭头并且选择正确的端口。
第 5 步：在受信接口地区中，请点击一个单选按钮设置特定端口到委托或没委托，然后点击适用。
Note:在本例中，是被选择表明配置端口是一个可信的端口。
第6.步。一旦成功消息出现，请点击Close。
步骤7.，如果当前应用，请验证在委托的接口表里在选择的端口的新被配置的设置。
第8.步(可选)永久保存配置，点击闪亮 
图标在页的顶部部分。
您应该成功当前配置了在您的交换机的受信接口设置。
