WLAN-二层隧道转发_无法识别

配置

由于AP无法识别带VLAN Tag 254的帧，所以交换机连接AP的Trunk接口要配置PVID

隧道转发模式，AC上 配置所需VLAN 10 254

AP上线认证方式默认为MAC认证，实验中配置为无认证

可创建AP组，或直接在AP中引用VAP配置文件

修改国家码命令，默认不需要修改

regulatory-domain-profile name default
 country-code CN

SW1：

sysname SW1
#
vlan batch 10 254
#
interface Vlanif10
 ip address 10.1.1.254 255.255.255.0
 dhcp select interface
#
interface Vlanif254
 ip address 10.1.254.254 255.255.255.0

#
interface GigabitEthernet0/0/2

SW1连接AP的接口还可以配置成access或hybrid

acess：

interface GigabitEthernet0/0/2
 port link-type access
 port default vlan 254
#

hybrid：

interface GigabitEthernet0/0/2
 port hybrid pvid vlan 254
 port hybrid untagged vlan 254
#

AC1：

sysname AC1
#
vlan batch 10 254
#

转发流程

STA ping 网关，数字1-4对应下面的抓包

WLAN-二层隧道转发_无法识别_07

1.icmp数据包被封装在capwap协议中，由AP单播发送给AC，内层vlan10，外层vlan254

WLAN-二层隧道转发_无法识别_08

收到capwap报文后解封装，根据内层报文转发
