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 operating modes
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
Routing functions
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
Rapid Spanning Tree 802.1d Spanning Tree and 802.1w Rapid Spanning Tree support for dynamic path selection with redundant layer 2 connections
