S5560X-30F-EI+DHCP address range无法配置

设备类型：S5560X-30F-EI

软件版本：S5560X-6628P47

问题描述：

配置DHCP的address range报错There are IP addresses allocated in the current range，

dhcp server ip-pool vlan16

 gateway-list 192.168.16.1

 network 192.168.16.0 mask 255.255.255.0

 dns-list 202.96.209.133 202.96.209.5

配置address range时候报错

address range 192.168.16.6 192.168.16.10

There are IP addresses allocated in the current range. 

但实际上这个地址段没有使用。

我用HCL模拟器模拟却可以配置
