SSID/VLAN/Security
The AP provides several security features to protect your network from unauthorized access. The SSID/VLAN/Security tab contains the
following sub-tabs that allow for configuration of security features:
•
Management VLAN
• Security Profile
• MAC Access
• Wireless
The AP also provides Broadcast SSID/Closed System and Rogue Scan to protect your network from unauthorized access. See the Broadcast
SSID and Closed System and Rogue Scan sections from more information.
Management VLAN
VLAN Overview
Virtual Local Area Networks (VLANs) are logical groupings of network hosts. Defined by software settings, other VLAN members or resources
appear (to clients) to be on the same physical segment, no matter where they are attached on the logical LAN or WAN segment. They simplify
traffic flow between clients and their frequently-used or restricted resources.
VLANs now extend as far as the reach of the access point signal. Clients can be segmented into wireless sub-networks via SSID and VLAN
assignment. A Client can access the network by connecting to an AP configured to support its assigned SSID/VLAN.
AP devices are fully VLAN-ready; however, by default VLAN support is disabled. Before enabling VLAN support, certain network settings
should be configured, and network resources such as a VLAN-aware switch, a RADIUS server, and possibly a DHCP server should be
available.
Once enabled, VLANs are used to conveniently, efficiently, and easily manage your network in the following ways:
•
Manage adds, moves, and changes from a single point of contact
• Define and monitor groups
• 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.
