Table 2. New Cisco Wireless LAN Controller Features

Feature

Description

Benefit

Controller Auto- Provisioning

Network administrators can configure wireless LAN controllers (WLC) during boot-up. Users can connect a new WLC to the network, turn on the new device, and have it configured automatically from a pre-existing configuration file.

The AutoInstall process begins any time a Cisco WLC is turned on and a valid configuration file is not found in nonvolatile random-access memory (NVRAM).

Auto-provisioning simplifies large WLC deployments in multiple branch offices or remote locations where network expertise is not readily available. It also facilitates centralized management of the controller installation.

High Availability

Access point and client downtime is reduced by shortening the failure detection time, avoiding the restart of Dynamic Host Configuration Protocol (DHCP) process by reusing the same IP address to reinitiate the discovery process, and enhancing the access point discovery process.

This feature reduces client downtime and results in higher network availability. It also helps to maintain better data and voice sessions, and helps to ensure a consistent end-user experience. This is especially beneficial for industries such as financial services and healthcare.

Hybrid Remote Edge Access Point (HREAP) (802.1x authentication on the access point)

This feature will add the ability for the HREAP to perform 802.1 x authentications on the access point when the WAN connection is down. It uses a preconfigured list of usernames and passwords.

HREAP can authenticate users during a WAN outage without additional hardware, thus providing business continuity.

Increased Scalability

Roaming is now supported across 48 controllers. The controller provides inter-subnet mobility for clients by sending mobility messages to other member controllers.

WLAN controllers expand the mobility space where users can roam across 48 controllers. This provides greater coverage as users roam across a larger network area.

Benefit

Auto-Provisioning of Wireless LAN Controllers

Cisco WCS can automatically configure a new Cisco Wireless LAN Controller when it is detected on the wireless network.

The wireless LAN controller can be located locally or remotely.

Customers with large WLAN deployments using numerous wireless LAN controllers can reduce their WLAN setup time by using the automatic provisioning feature for wireless LAN controllers available through Cisco WCS. This allows network managers to send wireless LAN controllers to branch offices that do not have IT resources and configure these controllers remotely. This helps reduce operational costs and streamlines operations.

Scheduled Shut Off of WLAN and Access Point Radios

A scheduled configuration change of the operational mode (on/off) for Cisco Aironet lightweight access points can be set by Cisco WCS.

Customers can deactivate the unified wireless LAN as needed to meet their security requirements during business or nonbusiness hours.

Google Earth Integration

Google Earth can be launched and used, from within Cisco WCS, to correlate the location and define the RF coverage area of a Cisco Aironet lightweight outdoor mesh access point using the Google Earth map features.

A variety of Google Earth map features can be used within Cisco WCS, including zoom, pan, and tilt.

Google Earth must be installed to enable this feature. (Google Earth Pro is recommended.)

Google Earth features and functionality can be used by Cisco WCS to assist with visualizing and managing Cisco Aironet outdoor mesh wireless LAN deployments.

Diagnostic Channel Security Enhancements for Cisco Compatible Extensions Version 5 Client Devices

Cisco Compatible Extensions Version 5 client devices can request diagnostic channel association to the client to assist with troubleshooting.

A consolidated summary of the troubleshooting tests that were used on the diagnostic channel in conjunction with Cisco Compatible Version 5 client devices can be generated.

Security

Cisco Wireless LAN Controller Integration with Cisco Security Monitoring, Analysis and Response System v5.3.1 (MARS)

Cisco Security MARS traps and parses events from the Cisco Wireless LAN Controller to create a single view of both wired and wireless security events. Cisco Security MARS then identifies threats, suggests mitigation actions that comply with networkwide policies, and generates reporting of security events.

The integration enables event aggregation and correlation within the Cisco Security MARS environment and suggested mitigation actions. Cisco Security MARS performs incident notification and reporting based on current Cisco Security MARS framework.

The integration provides a consolidated view of both the wired and wireless networks, enhanced visibility into the security and network information, and increased ability to identify, prioritize, and respond to network faults and attacks.

This also delivers increased reporting capabilities, compliance, and adherence to network policies.

Expanded Wireless Intrusion Detection System Detection, False Alarm Reduction, and WCS Tuning

Expanded functionality of the wireless intrusion detection system (wIDS) with new signatures including: ASLEAP (LEAP crack tool), 802.11n-specific protocol attributes, 802.11n authentication flood attacks, honeypot access points, and fake access point detection for high-density access point environments.

wIDS signature tuning and management enhancements in Cisco WCS provide a reduction in false alarms and increased event fidelity. New configurable "interval" keyword for all IDS signatures allows consolidation of reporting and alarms for repeating events within a particular timeframe.

Network security is improved with increased detection capabilities, new signatures and identification of 802.11n threats.

Reduced false alarms make administration and maintenance requirements easier to manage.

Rogue Auto-Classification, Expanded Detection

Rule-based classification simplifies and automates rogue event classification through flexible and admin-customizable detection criteria. Additionally, detection has been expanded to include 802.11n-specific rogue access points and to recognize and mark autonomous access points as friendly or nonrogue.

The increased ability to identify and locate rogue access points and devices and determine their current state (while decreasing number of false alerts) lowers operation costs associated with rogue mitigation. It also provides more granular control over detection, policies, and reporting of rogue activities.

Guest Access

Login Failure Message Web Page Customization

Administrators can customize a login failure message Web page per service set identifier (SSID). The customized message can be easily uploaded to the controller via an HTML file.

A customized login failure message with directions for the guest user can reduce help desk calls associated with a guest user being rejected from the network.

Logout Verification Message Web Page Customization

Administrators can customize a logout verification message Web page per SSID. The customized message can be easily uploaded to the controller via an HTML file.

A logout verification Web page verifies the user has logged off the network. The page is fully customizable and thus important messages can be communicated, enhancing the overall guest-user experience and potentially minimizing help desk calls.

Guest Account Creation Limits

Administrators can limit the number of guest users a sponsor (provisioning personnel) can create during a given time period (hours, days, weeks, months).

Limiting the number of guest users a sponsor can provision provides IT with tighter control over guests accessing the network, and the sponsors who are provisioning them, thereby improving overall security.

LDAP Web Authentication Support for Guest Access

Administrators can now authenticate guest users via Web authentication using their existing LDAP infrastructure.

Organizations that use LDAP as their authentication protocol can use their current authentication infrastructure for guests accessing the network. This feature ultimately improves investment protection as well as ease of management, as administrators no longer need to manage multiple authentication databases.

Support for Proprietary Guest Access Solutions

Administrators can integrate their guest solution (WLC and WCS) with proprietary, third-party guest access provisioning or reporting solutions.

This integration provides proprietary, third-party guest access solutions with improved reporting and visibility into guest user activity, thus improving flexibility. Additionally, the ability to import or export guest user statistics between third-party systems and WCS improves ease of management.

Voice Services

WoWLAN Audit Tool

This tool automates configuration checks by allowing customers to define a set of rules in the WCS to validate the configuration of a group of controllers based on the VoWLAN deployment guide recommendations. Violations of the configuration can be presented in the form of a report or alarm.

This check can be performed periodically or manually.

Organizations save a considerable amount of time when performing configuration checks of the controllers based on suggested VoWLAN deployment guidelines.

Cisco Wireless Location Appliance

Table 6. New Cisco 2700 Series Wireless Location Appliance Features

Feature

Description

Benefit

Site Survey Calibration Enhancements

Collecting data points to perform a calibration site survey to support location can be more easily and accurately attained through the following enhanced calibration methods:

Point calibration: User clicks a point on the WCS map and rotates or moves a laptop within the surrounding area. The system receives received signal strength indication (RSSI) values from the controller and determines the variations
Linear calibration: Users needing to perform linear calibration along walls or down corridors can collect data between two different points. While moving the client between the points, RSSI data is collected and the distribution path analyzed for accuracy.

Enhancements to the Site Survey Calibration features allow faster, simpler troubleshooting of the RF environment to help ensure improved location accuracy and to reduce the time required to do so by a third.

Location Optimized Monitor Mode

Location Optimized Monitor Mode (LOMM) is a new access point configuration that enables the detection of Wi-Fi tags even if a wireless network is not actively deployed.

LOMM access points can be easily added exactly where they are needed to provide ideal coverage and location accuracy without disrupting existing network configurations.

LOMM access points are well suited for multiservice network environments that support voice or IDS already and want to add location without causing network interference.

Location Optimized Monitor Mode allows organizations to easily implement location to detect mobile assets equipped with Wi-Fi tags, such as wheelchairs or manufacturing parts, without disrupting the existing network.

In a mixed network environment, adding LOMM access points to support location of Wi-Fi tags conserves network resources and maximizes utilization.

Location Accuracy Tool

The Location Accuracy tool improves the usability of current accuracy testing by providing point-and-click test execution and user friendly reports for enhanced accuracy measurement, including basic troubleshooting, inter-floor level accuracy, and alarm notification reports.

The Location Accuracy tool provides network administrators with increased visibility to issues impacting location accuracy within the RF environment.

The tool simplifies location troubleshooting by providing quick access to test results and reports enabling faster problem resolution.

Location History Enhancements

Enhancements to the Location History feature allow location tracking information to be collected and stored based on the occurrence of specific events.

A transition tracking algorithm logs location events triggered by a predefined condition including when a Wi-Fi tag:

• Changes floor location
• Enters or leaves a specified area
• Moves beyond a 30 foot distance

The Location History feature enables more effective management, storage, and reporting of location tracking data by capturing only predefined significant location events.
