那为什么wa4330的ap就可以配置呢，配置如下：

wlan ap a-ap19 model WA4330-ACN
serial-id 210235A1K6C188000611
map-configuration flash:/newmap1.txt
vlan 1
radio 1
channel 48
max-power 3
rate mandatory 24
rate multicast auto
rate supported 18 36 48 54
rate disabled 6 9 12
radio enable
channel auto-select whitelist 36 40 44 48
channel band-width 40
option roam-navigation enable rssi 20 beacon-power 20
option client reconnect enable rssi 20
service-template 10
service-template 12
service-template 3
service-template biyao_js1
client max-count 20
radio 2
max-power 3
radio enable
channel auto-select whitelist 149 153 157 161 165
channel band-width 40
option roam-navigation enable rssi 20 beacon-power 20
option client reconnect enable rssi 20
service-template 10
service-template 12
service-template biyao_js1
client max-count 20

应该是radio1和radio2同属一个频段，所以只能配置一个，除次之外就只能是bug了
