1/直连二层组网直接转发
配置建议
建议在与AP直连的设备接口上配置端口隔离，如果不配置端口隔离，尤其是业务数据转发方式采用直接转发时，可能会在VLAN内形成大量不必要的广播报文，导致网络阻塞，影响用户体验。
隧道转发模式下，管理VLAN和业务VLAN不能配置为同一VLAN，且AP和AC之间只能放通管理VLAN，不能放通业务VLAN。
配置配置
1 GW配置
[r1]inter g0/0/0
[r1-GigabitEthernet0/0/0]ip add 192.168.101.100 24
2 SW配置（接入层）
[sw]vlan batch 100 101
interface Ethernet0/0/1
port link-type trunk
port trunk pvid vlan 100
port trunk allow-pass vlan 100 to 101
interface Ethernet0/0/2
port link-type trunk
port trunk pvid vlan 100
port trunk allow-pass vlan 100 to 101
port-isolate enable group 1
3 AC配置
接口状态
interface Vlanif100
ip address 192.168.100.1 255.255.255.0
dhcp select interface //配置接口的DHCP
#
interface Vlanif101
ip address 192.168.101.1 255.255.255.0
dhcp select interface //配置接口的DHCP
dhcp server excluded-ip-address 192.168.101.100 //排除GW的IP地址
AC-WLAN配置
[AC6005]dis thiscapwap source interface vlanif100
[AC6005]wlan
[AC6005-wlan-view]ap-gr
[AC6005-wlan-view]ap-group name wfy

Ac上还需要有一条默认路由指向上层路由器
2/直连二层组网隧道转发
现在是隧道模式，其特点如下
并且在该模式下，在AC和AP之间的交换机，仅可以放行AP的管理VLAN通行即可
实际配置
Gw不变，
SW1
interface Ethernet0/0/2
port link-type trunk
port trunk pvid vlan 10
port trunk allow-pass vlan 10
interface Ethernet0/0/1
port link-type trunk
port trunk allow-pass vlan 10
AC配置
[AC6005]capwap source inter vlan 10
interface GigabitEthernet0/0/2
port link-type trunk
port trunk pvid vlan 10
port trunk allow-pass vlan 10
interface GigabitEthernet0/0/1
port link-type access
port default vlan 20
#
interface Vlanif10
ip address 192.168.10.1 255.255.255.0
dhcp select interface
#
interface Vlanif20
ip address 20.0.0.2 255.255.255.0
dhcp select interface
dhcp server excluded-ip-address 20.0.0.1
WLAN配置
只有一处改动，
那就是在VAP模板中的forward-mode 转发模式
vap-profile name wfy
forward-mode tunnel
service-vlan vlan-id 20
ssid-profile wfy
security-profile wfy
OK no problem
其实最主要的就是要搞明白，接入交换机上接口的VLAN配置，以及trunk的配置，
究竟哪里设置pvid，哪里放行具体的vlan,
