Other security features of CiscoWorks WLSE include:
• Security policy monitoring—All access points on the network are monitored for consistent application of security policies. Alerts are generated for
violations and can be delivered by e-mail, syslog, or SNMP trap notifications.
• Monitoring of IEEE 802.1X server availability—IEEE 802.1X Extensible Authentication Protocol (EAP) servers, including Cisco Secure access
control servers (ACSs), are monitored for response time. Cisco LEAP, EAP-Flexible Authentication via Secure Tunneling (EAP-FAST), Protected
EAP (PEAP), and generic RADIUS authentication types are supported.
• Secure user interface—CiscoWorks WLSE provides a secure HTML-based user interface that may be accessed anywhere, even through firewalls.
In addition to the Web-based GUI, a command-line interface like that in Cisco IOS Software provides direct console, Telnet, or SSH access for
basic configuration and troubleshooting. CiscoWorks WLSE communicates with access points using HTTP Secure Sockets Layer (SSL) sessions
for management.
• Role-based access model—CiscoWorks WLSE has a flexible, role-based user access model. For example, help desk personnel can be limited to
viewing reports and faults. Several common authentication modules are supported, including TACACS+, RADIUS, and Microsoft NT Domain
authentication.
Performance Optimization and High Availability
Interference detection and location is critical to maintaining a reliable WLAN. RF measurements sent to CiscoWorks WLSE include measurements
for both 802.11 and non-802.11 interference. If the interference exceeds an administrator-defined threshold, a fault is generated so that the
administrator can quickly locate and suppress the source of the interference.
• Air/RF scanning and monitoring—Cisco Aironet access points are multifunctional, with built-in RF scanning and measurement capabilities.
CiscoWorks WLSE analyzes these RF measurements, provides notification if performance degrades, and displays air/RF coverage (Figure 2). It
also analyzes RF measurements from Cisco Aironet and Cisco Compatible client devices. Client air scanning and monitoring provides 10 to 20
times more RF measurement data than access-point RF measurements alone. Because WLAN clients can freely move about all areas of a building,
the addition of client scanning and monitoring extends RF monitoring into areas most likely to contain rogue access points while allowing for
more accurate detection.
