VLAN/SSID
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
