问题描述：
5130交换机做接入，上联口是汇聚5560，一开始配的是port trunk permit vlan all,后来剪裁vlan，改为了port trunk permit vlan 300 305 to 306 311 to 312 356 to 357 401 420 to 422，PC就获取不到地址了，汇聚和核心都可以获取到ip，PC配固定地址可上网。保存配置重启后PC就可以获取到ip，本网络中DHCP服务器在Windowsserver2012上。请问这是什么原因？怎么才可以不用重启就能自动获取ip。配置如下：

重启后就可以了，现在就想知道没重启之前为什么不能获取到ip，怎么解决，重启太费时间了，客户要求最好不要重启
