• Interference detection—CiscoWorks WLSE catalogs the physical location of all managed access points and creates a site map of the WLAN

installation. This allows the wireless-aware network to detect points of interfering RF energy that affect network performance. The source of this

energy could be a rogue access point or a device that operates in the same frequency range, such as a cordless telephone or leaky microwave oven.

Interference detection and location is critical to maintaining a reliable WLAN. Administrators can define thresholds to generate fault notifications

when detected interference levels are exceeded.

• Self-healing WLANs—CiscoWorks WLSE can detect and compensate for an access point that has failed by automatically increasing the power and

cell coverage of surrounding access points. The self-healing process provides contiguous coverage to maximize the available coverage of the

WLAN and minimize client impact.

• Automated resite surveys—CiscoWorks WLSE automatically reassesses radio throughput and performance to provide notification if performance

falls below administrator-defined thresholds. New optimal settings can be found by running the site survey wizard, then applied to the network.

• Warm standby redundancy—CiscoWorks WLSE supports redundancy through a primary and backup mechanism. If the primary fails, the backup

automatically takes over. Data such as performance data, fault messages, and radio scans between the primary and backup is synchronized on a

user-defined interval to minimize the loss of collected data when a backup takes over.

Reporting, Trending, Planning, and Troubleshooting

Real-time client tracking, together with a variety of reports, is a powerful tool for troubleshooting and capacity planning. Using only a client name,

user name (supported for Cisco LEAP and PEAP), or MAC address, it is easy to determine to what access point a client is associated in real time.

In addition, the previous 10 associations for the client and associated access points can be accessed to aid in troubleshooting.

Information about network utilization, client association and utilization, historical and current client usage statistics, Cisco Aironet Access Point

Ethernet and radio interfaces status, and error details are displayed in both graphical and tabular form. Reports may be generated both at the

individual device level and the group level. All reports may be scheduled, delivered by e-mail, or exported in comma separated value (CSV),

XML, and PDF formats.

CiscoWorks WLSE also provides comprehensive coverage display overlaid on floor maps to provide visibility into the RF environment. The

Location Manager feature provides coverage by data rate and signal strength. CiscoWorks WLSE also supports RF management for directional

antennas. Details about device settings, including channel and power, can be overlaid on the coverage display.

Integration

Integration with third-party network management systems is provided through syslog messages, SNMP traps, and an XML interface. As part of the

CiscoWorks network management series of products, CiscoWorks WLSE integrates with the CiscoWorks LAN Management Solution and other

CiscoWorks applications to increase the efficiency of managing a converged wired and wireless network. Device inventory and credentials, for

example, can be imported or exported between CiscoWorks WLSE and CiscoWorks Resource Manager Essentials (RME), an application that

provides broad network management for a wide range of Cisco devices. If desired, device discovery may be turned off to allow automatic inventory

synchronization with CiscoWorks RME. CiscoWorks WLSE uses the same default user roles as CiscoWorks RME, but it allows customization.

CiscoWorks WLSE can be launched from the CiscoWorks Cisco Management Connection desktop.
