最佳答案
就是三层漫游的时候需要开的，这样能实现客户端漫游时vlan保持不变。
V5的控制器如果需要一个服务模板绑定多个van都是必开的。
实验拓扑
实验需求
实现不同AP下联的属于相同SSID不同vlan的无线终端用户实现漫游。
实验配置
1、WX5540E AC板配置：
#
vlan 20 to 22
#
dhcp server ip-pool vlan20
network 192.168.20.0 mask 255.255.255.0
gateway-list 192.168.20.1
#
dhcp server ip-pool vlan21
network 192.168.21.0 mask 255.255.255.0
gateway-list 192.168.21.1
#
dhcp server ip-pool vlan22
network 192.168.22.0 mask 255.255.255.0
gateway-list 192.168.22.1
#
wlan service-template 200 clear
ssid GDJ
bind WLAN-ESS 200
service-template enable
#
#配置各VLAN的网关地址
interface Vlan-interface20
ip address 192.168.20.1 255.255.255.0
#
interface Vlan-interface21
ip address 192.168.21.1 255.255.255.0
#
interface Vlan-interface22
ip address 192.168.22.1 255.255.255.0
#
interface Bridge-Aggregation1
port link-type trunk
port trunk permit vlan all
#
interface WLAN-ESS200
port link-type hybrid
undo port hybrid vlan 1
port hybrid vlan 20 untagged
port hybrid pvid vlan 20
mac-vlan enable
#
wlan ap xhy model WA2620X id 1
priority level 6
serial-id 219801A0KTM144001504
radio 1
radio 2
service-template 200 vlan-id 21
radio enable
#
wlan ap xhy2 model WA2620i-AGN id 2
serial-id 219801A0CMC146000765
radio 1
radio 2
service-template 200 vlan-id 22
radio enable
#
dhcp enable
2、接入POE交换机配置
#
interface GigabitEthernet1/0/1
port access vlan 20
poe enable
#
interface GigabitEthernet1/0/2
port access vlan 20
poe enable
#
interface GigabitEthernet1/0/3
port access vlan 20
poe enable
3、AC交换板配置：
#配置与POE交换机相连的接口
interface GigabitEthernet1/0/5
port access vlan 20
实验配置
使用AP连接到SSID：GDJ上，查看此时获取到的IP地址是属于那个VLAN的：
获取到的为VLAN22的地址

此时由于wa2620i-AGN的信号过强，无法实现漫游，手工关闭wa2620i-AGN的射频口触发终端漫游
[WX5540E-wlan-ap-xhy2-radio-2]radio disable
终端没有掉线，无缝切换到WA2620X的射频上。
查看此时的客户端状态：
