Performing Advanced Configuration
Reduce broadcast and multicast traffic to unnecessary destinations
•
- Improve network performance and reduce latency
Increase security
•
- Secure network restricts members to resources on their own VLAN
- Clients roam without compromising security
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.

3. AP management via wired host (SNMP, Web interface or CLI)
4. DHCP Server
5. RADIUS Server
6. VLAN 1
7. VLAN 2
