AC+AP通信原理

ap1是ap的配置 POE-SW是连接ap的配置，做了本地转发，现有的问题是ap的pvid是1，而sw上面的没有untaged1，反过来sw的pvid是100，ap上面没有untaged，他们是怎么剥离802.1Q标签的呢？

<ap1>dis vlan

 Total VLANs: 3

 The VLANs include:

 1(default), 10, 20

#

interface GigabitEthernet1/0/1

 port link-type trunk

 port trunk permit vlan 1 10 20

<ap1> dis int g1/0/1

GigabitEthernet1/0/1

PVID: 1

Port link-type: Trunk

 VLAN Passing:   1(default vlan), 10, 20

 VLAN permitted: 1(default vlan), 10, 20

 Trunk port encapsulation: IEEE 802.1q

POE-SW

interface GigabitEthernet1/0/7

 port link-type trunk

 undo port trunk permit vlan 1

 port trunk permit vlan 10 20 100

 port trunk pvid vlan 100

 poe enable

[POE-SW-GigabitEthernet1/0/7]dis int g1/0/7

GigabitEthernet1/0/7

PVID: 100

MDI type: Automdix

Port link-type: Trunk

 VLAN Passing:   10, 20, 100

 VLAN permitted: 10, 20, 100

 Trunk port encapsulation: IEEE 802.1q
