Overview of the SCALANCE WLC711 Solution
SCALANCE WLC711 and Your Network
SCALANCE WLC711
User Guide, V8.11, 07/2012, C79000-G8976-C260-03 1-9
produces a Pairwise Master Key which is used by the AP and the user to derive their temporal
keys. (The keys change over time.)
The SCALANCE WLC711 solution provide a RADIUS redundancy feature that enables you to
define a failover RADIUS server in the event that the active RADIUS server becomes
unresponsive.
Privacy
Privacy is a mechanism that protects data over wireless and wired networks, usually by
encryption techniques.
SCALANCE WLC711 supports the Wired Equivalent Privacy (WEP) standard common to
conventional access points.
It also provides Wi-Fi Protected Access version 1 (WPA v.1) encryption, based on Pairwise Master
Key (PMK) and Temporal Key Integrity Protocol (TKIP). The most secure encryption mechanism
is WPA version 2, using Advanced Encryption Standard (AES).
Virtual Network Services
Virtual Network Services (VNS) provide a versatile method of mapping wireless networks to the
topology of an existing wired network.
A VNS is the binding of reusable components:
WLAN Service components that define the radio attributes, privacy and authentication
settings, and QoS attributes of the VNS
Policy components that define the topology (typically a VLAN), filter rules, and Class of
Service applied to the traffic of a station.
Figure 1-4 illustrates the transition of the concept of a VNS to a binding of reusable components.
