Lancom Systems L-54AG User Manual

LANCOM L-54ag Wireless

Scope of features: as of LCOS version 7.5x

Radio channels 2.4 GHz

Up to 13 channels, max. 3 non- overlapping (2.4 GHz band)

Radio channels 5 GHz

Up to 19 non- overlapping channels (5 GHz band) with automatic dynamic channel selection (DFS 2)

Roaming

Seamless handover between radio cells, IAPP support, IEEE 802.11d  support

802.11i fast roaming

Pre- authentication and PMK caching for fast roaming

Fast client roaming

With background scanning, moving LANCOM "client mode" access points pre- authenticate to alternative access points which 
offer a better signal before Roaming

VLAN

VLAN ID definable per interface, WLAN SSID, point- to- point connection and routing context (4094 IDs)

Dynamic VLAN assignment

Dynamic VLAN assignment for target user groups based on MAC addresses, BSSID or SSID by means of external RADIUS server.

Q- in- Q tagging

Support of layered 802.1q VLANs

Multi- SSID

Simultaneous use of up to 8 independent WLAN networks per WLAN interface

Security

IEEE 802.11i / WPA2 with passphrase or 802.1x and hardware- accelerated AES, closed network, WEP64, WEP128, WEP152, 
user authentication, 802.1x /EAP

RADIUS server

Integrated RADIUS server for MAC address list management

EAP server

Integrated EAP server for authentication of 802.1x clients via EAP- TLS, EAP- TTLS, PEAP, MSCHAP or MSCHAPv2

Quality of Service

Prioritization according to Wireless Multimedia Extensions (WME, subset of IEEE 802.11e)

Bandwidth limitation

Each WLAN client (MAC address) can be assigned maximum transmit and receive rates and to an individual VLAN ID

Background scanning

Detection of rogue AP's and the channel information for all WLAN channels during normal AP operation.

The Background Scan Time Interval defines the time slots in which an AP or Router searches for a foreign WLAN network in its 
vicinity. The time interval can be specified in either milliseconds, seconds, minutes, hours or days.

Client detection

Rogue WLAN client detection based on probe requests

802.1x supplicant

Authentication of an access point in WLAN client mode at another access point via 802.1X (EAP- TLS, EAP- TTLS and PEAP)

Note

* The effective distance and transmission rate that can be achieved are depending of the site RF conditions.

WLAN access point

Infrastructure mode (autonomous operation or managed by LANCOM WLAN Controller)

WLAN bridge

Point- to- multipoint connection of up to 7 Ethernet LANs (mixed operation optional), broken link detection, blind mode, up to 
32 VLANs simultaneously for WLAN connections.

When configuring Pt- to- Pt links, pre- configured names can be used as an alternative to MAC Adresses for creating a link.

WLAN router

Use of the LAN connector for simultaneous DSL over LAN, IP router, NAT/Reverse NAT (IP masquerading) DHCP server, DHCP 
client, DHCP relay server, DNS server, PPPoE client (incl.Multi- PPPoE), PPTP client and server, NetBIOS proxy, DynDNS client, 
NTP, port mapping, policy- based routing based on routing tags, tagging based on firewall rules, dynamic routing with RIPv2, 
VRRP, spanning- tree protocol to support redundant routes in Ethernet networks

WLAN client

Transparent WLAN client mode for wireless Ethernet extensions, e.g. connecting PCs or printers by Ethernet; up to 64 MAC 
addresses

Router

IP and NetBIOS/IP multi- protocol router

Advanced Routing and Forwarding

Separate processing of 8 contexts due to virtualization of the routers. Mapping to VLANs and complete independent 
management and configuration of IP networks in the device, i.e. individual settings for DHCP, DNS, Firewalling, QoS, Routing 
etc.

HTTP

HTTP and HTTPS server for configuration by web interface

DNS

DNS client, DNS server, DNS relay, DNS proxy and dynamic DNS client

DHCP

DHCP client, DHCP relay and DHCP server with autodetection

NetBIOS

NetBIOS/IP proxy

NTP

NTP client and SNTP server, automatic adjustment for daylight- saving time

Policy- based routing

Policy- based routing based on routing tags. Based on firewall rules, certain data types are marked for specific routing, e.g. to 
particular remote sites or lines.

Dynamic routing

Dynamic routing with RIPv2. Learning and propagating routes; separate settings for LAN and WAN. Extended RIPv2 including 
HopCount, Poisoned Reverse, Triggered Update for LAN (acc. to RFC 2453) and WAN (acc. to RFC 2091) as well as filter options 
for propagation of routes
