问题描述：

我S5500上做了很多dhcp server，划分了好几个网段，但是今天突然获取不到IP，只有一个网段可以获取到，其他都获取不到，固定IP可以用。[crown-shjfhx]dis dhcp server free-ip IP Range from 172.16.2.1 to 172.16.2.1 IP Range from 172.16.2.21 to 172.16.2.27 IP Range from 172.16.2.29 to 172.16.2.33 IP Range from 172.16.2.35 to 172.16.2.39 IP Range from 172.16.2.41 to 172.16.2.42 IP Range from 172.16.2.63 to 172.16.2.199 [crown-shjfhx]dis dhcp server ip-in-use pool 2fuser IP address Client-identifier/ Lease expiration Type Hardware address --- total 0 entry ---

您好，请知：

1、可使用reset dhcp server ip-in-use释放所有IP后看是否可以获取。

2、另外使用dis logbuffer看下是否有相应的报错提示。

3、也可使用reset dhcp server statistics命令释放连接再看下。

4、如果还是不行，且条件允许，重启交换机再观察。

都试过，还都是不行
