VLAN tagged data is collected and distributed through an AP's wireless
interface(s) based on Network Name (SSID). An Ethernet port on the
access point connects a wireless cell or network to a wired backbone.
The access points communicate across a VLAN-capable switch that
analyzes VLAN-tagged packet headers and directs traffic to the
appropriate ports. On the wired network, a RADIUS server authenticates
traffic and a DHCP server manages IP addresses for the VLAN(s).
Resources like servers and printers may be present, and a hub may
include multiple APs, extending the network over a larger area.
In this figure, the numbered items correspond to the following
components:
1. VLAN-enabled access point
2. VLAN-aware switch (IEEE 802.1Q uplink)
3. AP management via wired host (SNMP, Web interface or CLI)
4. DHCP Server
5. RADIUS Server
6. VLAN 1
7. VLAN 2
