Lancom Systems WLC-4006+ 62035 Manuel D’Utilisation

A WLAN controller is a secure and convenient way to manage all of your access points and WLAN routers, whether they are in the local network, at branch offices or at

teleworkers' homes. Controllers can centrally manage firmware updates for the remote devices, and they provide an efficient way of handling configuration and servicing

operations. When you are managing small networks, you no longer have to make any compromises in terms of security and administrative convenience: Ex-factory, the

LANCOM WLC-4006+ supports management of up to 6 access points, making it ideal for the professional administration of small networks. This provides 24/7 monitoring

of the administrator's WLAN settings even in a very small network or, for example, the operation of a hotspot featuring secure user authentication thanks to the integrated

Public Spot function. If the local WLAN network grows larger, or if new sites have to be added in, the WLC can easily be upgraded with +6 Option to handle a maximum

of 30 access points.

In any situation where network security depends on a central component like the controller, appropriate mechanisms must exist to prevent a downtime of the network in

case of its failure. An intelligent and reliable approach is provided by the LANCOM Smart Controller principle: While the administrative data are routed through the

controller, traffic from the client is sent to the access point, and from there directly to the router. If a controller fails, the access point switches to "stand-alone mode" and

the communication between the client and access point remains intact. This way, the operation of the network can be upheld for a predefined period of time. This avoids

the occurrence of downtimes during everyday business through employees losing access to the network or the failure of WLAN-controlled production facilities.

Which is the quickest way to configure hotspot access that is securely separated from the underlying corporate network, without having to adjust the company's existing

VLAN infrastructures? One way would be, for example, to set up a layer-3 tunnel on the LANCOM WLC-4006+. The layer-3 tunnel transports encapsulated layer-2 packets

to the controller, so that no changes have to be made to existing VLANs. This saves the administrator considerable amounts of work, especially in more complex networks.

Which clients are active in the WLAN right now? Are all access points operating with the company-wide security policies as set up by the administrator, or are there rogue

devices on the network? How are the signal strengths from the access points? How much load is there on the network, what are the available data rates? To help

administrators answer these questions, LANCOM offers a variety of software packages that match the size of your network and meet your needs precisely. These packages

range from free, practical monitoring and configuration tools for very small networks (LCMS) up to comprehensive management solutions such as the LANCOM Large Scale

Monitor for medium-sized to very large networks. More information is available from www.lancom.eu/lsm.

Advanced Routing and Forwarding (ARF) from LANCOM is a unique technology for network virtualization. It enables different logical networks, each with their own settings

for DHCP, DNS, routing, and firewall, to operate on a single device and share the same physical infrastructure. For example, networks in the LAN can be assigned to

different VLANs as tagged in the WAN, or assigned to different RAS connections. This network separation continues over the air interface into the wireless LAN: a device

can operate different subnets, known as SSIDs, which are available for different user groups. Each SSID can be encrypted as necessary or provided with a user authentication

(e.g. via 802.1x), to ensure that the data are securely separated. This technique allows a single WLAN infrastructure to support separate networks for the management

board, employees, and customers.

From the very start, LANCOM products are designed for a product life of several years. They are equipped with hardware dimensioned for the future. Even reaching back

to older product generations, updates to the LANCOM Operating System – LCOS – are available several times a year, free of charge and offering major features. LANCOM

offers unbeatable safeguarding of your investment.
