Network requirements
As shown in Figure 32 , wireless clients access the Internet through BAS. The packets sent out of the wired
port of the AP are tagged with VLAN 1001 when arriving at L2 switch, and then tagged with VLAN 100
when arriving at L3 switch. When the packets reach AC, they carry outer VLAN tag 100 and inner VLAN
tag 1001. Configure WLAN QinQ, so that the packets from the clients are QinQ packets (carrying outer
VLAN tag 200 and inner VLAN tag 2001) when forwarded by AC to BAS.
