functionality is disabled, a client computer cannot connect to the AP interface with an
"any" SSID; the correct SSID has to be specified on client computers.
MAC-address-based access control.
Blocking unauthorized wireless client
computers based on MAC (Media Access Control) addresses. The ACL (Access
Control List) can be downloaded from a TFTP server.
WPA (Wi-Fi Protected Access).
The AP interface supports the WPA standard
proposed by the Wi-Fi Alliance (
http://www.wi-fi.org
). Both WPA-PSK (Pre-Shared
Key) mode and full WPA mode are supported. WPA is composed of TKIP (Temporal
Key Integrity Protocol) and IEEE 802.1x and serves as a successor to WEP for better
WLAN security.
IEEE 802.1x/RADIUS.
User authentication and dynamic encryption key distribu-
tion can be achieved by IEEE 802.1x
Port-Based Network Access Control
and RA-
DIUS (
Remote Authentication Dial-In User Service
).
Wireless client isolation.
Wireless-to-wireless traffic among the associated wire-
less clients can be blocked so that the wireless clients cannot see each other. This ca-
pability can be used in hotspots applications to prevent wireless hackers from attack-
ing other wireless users’ computers.
AP load balancing.
Several APs can form a load-balancing group. Within a group,
wireless client associations and traffic load can be shared among the APs. This func-
tion is available when the AP is in AP/Bridge mode.
Link integrity.
If the Ethernet LAN interface is detected to be disconnected from
the wired network, all currently associated wireless clients are disassociated by the
AP and no wireless client can associate with it.
Association control.
When the AP is in AP/Bridge mode, it can be configured to
deny association requests when it has served too many wireless clients or traffic load
is too heavy.
Associated wireless clients status.
Showing the status of all wireless clients
that are associated with the AP interface.
LAN-to-LAN bridge interface
6 Bridge links.
The bridge provides 6 bridge links based on the WDS (Wireless
Distribution System) technology, so that it can wirelessly connect to at most 6 other
wireless bridges, APs, or wireless routers with WDS support.
Antenna alignment assistance
.
The DRBAP provides a WDS link quality indi-
cator via Wireless Network Manager to facilitate alignment of directional antennas
when deploying pairs of wireless bridges.
Link health monitoring.
This feature enables the administrator to see if the WDS
links of the DRBAP to other peer wireless bridges are working fine.
RF type selection.
The RF type of each WLAN interface can be configured to work in
IEEE 802.11b only, IEEE 802.11g only, or mixed mode (802.11g and 802.11b simultane-
ously).
64-bit and 128-bit WEP (Wired Equivalent Privacy).
Data transmitted over AP or
