vlan pool技术主是是解决在大型组网中全部显示一个名称SSID，但不同区域连接的用户对应不同的vlan，这样防止一个vlan太多用户，广播域太大，以实现一个SSID对应一堆vlan，且可以实现漫游。
用hash算法比较常用：
AC命令行配置（命令和图形配置不对，是按自定义AC配置逻辑写的）：
dis current-configuration
vlan batch 100
vlan pool vlan_pool_test //定义业务vlan地址池
vlan 11 to 12
assignment hash
//用哈希方式分配，也可以用顺序方法，看现场情况，终端比较固定的用hash，不固定的多变的用顺序

接入交换机上也要相应放行这些vlan:
interface Ethernet0/0/1
port link-type trunk
port trunk allow-pass vlan 11 to 12 20 192
interface Ethernet0/0/2
port link-type trunk
port trunk pvid vlan 192
