  1. Optimizing Converged Cisco Networks (ONT) Module 6: Implement Wireless Scalability

  2. Module 6: Implement Wireless Scalability Lesson 6.3: Managing WLANs

  3. Objectives • Identify the components of Wireless LAN networks. • Describe the differences between distributed and centralized WLANs. • Describe the purpose and features of the CiscoWorks Wireless LAN Solution Engine. • Describe the purpose and features of the Cisco Wireless Control System. • Explain how the Cisco Location device can be used in WLANs.

  4. Cisco Unified Wireless Network

  5. Cisco Unified Wireless Network (Cont.)

  6. Cisco WLAN Implementation • Distributed WLAN solution • Autonomous AP • Wireless LAN Solution Engine (WLSE) • Centralized WLAN solution • Lightweight AP • Wireless LAN Controller (WLC) Cisco offers 2 “flavors” of wireless solutions:

  7. Wireless LAN Solution Components

  8. Autonomous WLAN: Autonomous access point Configuration of each access point Independent operation Management via CiscoWorks WLSE and WDS Access point redundancy Lightweight WLAN: Lightweight access point Configuration via Cisco Wireless LAN Controller Dependent on Cisco Wireless LAN Controller Management via Cisco Wireless LAN Controller Cisco Wireless LAN Controller redundancy Comparison of the WLAN Solutions

  9. CiscoWorks WLSE Software Features • CiscoWorks WLSE is a solution for managing the Cisco autonomous access point infrastructure: • Configuration of access points • Fault and policy monitoring • Reporting • Firmware upgrade on access points and bridges • Radio management • CiscoWorks WLSE administration • Deployment wizard for access points

  10. CiscoWorks WLSE Key Benefits • Improved WLAN security • Simplified access point deployment • RF visibility • Dynamic RF management • Simplified operations

  11. CiscoWorks WLSE and CiscoWorks WLSE Express CiscoWorks WLSE CiscoWorks WLSE Express • Both offer centralized management appliance for autonomous access point solutions • CiscoWorks WLSE Express: • Used for SMB, commercial, and branch offices (up to 100) • AAA server included • CiscoWorks WLSE: • Used for medium-to-large enterprises (up to 2500) • Requires external AAA server

  12. Simplified CiscoWorks WLSE Express Setup • Setup options: • Automatic configuration download from DHCP server: • DHCP enabled by default • Options 66 and 67 provide TFTP IP address and filename • Use setup command to configure CiscoWorks WLSE Express

  13. CiscoWorks WLSE Configuration Template

  14. CiscoWorks WLSE Benefits

  15. Cisco Wireless Control System (WCS) Features • Solution for managing Cisco lightweight access point infrastructure • Flexible and secure network management tool: • Intuitive GUI • Browser accessible via HTTPS • Device management via SNMP(supports SNMPv1, SNMPv2, and SNMPv3) • Ease of system maintenance • Three versions of Cisco WCS: • Cisco WCS Base • Cisco WCS Location • Cisco WCS Location + Cisco 2700 Series Wireless Location Appliance

  16. Cisco WCS Versions

  17. Cisco WCS Base Software Features • Autodiscovery of access points • Autodiscovery of rogue access points • Map-based organization of access point coverage areas • User-supplied campus, building, and floor plan graphics • System-wide control of streamlined network, controller, and managed APs: • Configuration with customer-defined templates • Status and alarm monitoring • Automated and manual data client monitoring and control • Automated monitoring of rogue APs, coverage holes, security violations, controllers, and APs • Full event logs • Automatic channel and power level assignment • User-defined automatic controller status audits, missed trap polling, configuration backups, and policy cleanups

  18. Cisco WCS Location Software Features • All Cisco WCS Base software features • On-demand location of rogue access points to within 33 feet(10 meters) • On-demand location of clients to within 33 feet • Ability to use Cisco Wireless Location Appliances

  19. Cisco WCS System Requirements • Runs as a normal application or a service on: • Microsoft Windows 2000 • Microsoft Windows 2003 • Red Hat Enterprise Linux ES • Configures and monitors one or more WLAN controllers and associated access points.

  20. Cisco WCS Network Summary Page All reporting is available for a seven day rolling window to allow detailed trending reports.

  21. Cisco WCS Controller Summary Page Cisco WCS can support 50 Cisco Wireless Controllers and 1500 access points.

  22. Cisco Wireless Location Appliance Overview • Cisco 2710 Series Wireless Location Appliances combine the features of a Cisco WCS server and a stand alone chassis to: • Compute historical location data • Collect historical location data • Store historical location data • Configuration and operation uses Cisco WCS with an easy-to-use GUI. • Uses a CLI console session for initial configuration before using the GUI.

  23. Cisco Wireless Location Appliance Architecture

  24. Cisco Wireless Location Appliance Applications • Visibility and tracking of 1500 mobile devices for 30 days • Work-flow automation and people tracking • Telemetry • WLAN security and network control • RF capacity management and visibility

  25. Self Check • Which type of WLAN deployment uses controllers and lightweight APs? • What is the purpose of the controller? • How is the Wireless Location Appliance used?

  26. Summary • The Cisco Unified Wireless Network is an end-to-end unified wired and wireless network that cost-effectively addresses WLAN security, deployment, management, and control issues. • The distributed WLAN solution is based on autonomous access points and uses the Wireless LAN Solution Engine (WLSE) for management. The centralized WLAN solution is based on lightweight access points and wireless LAN controllers. • The Cisco Wireless Location Appliance uses advanced RF fingerprinting technology to track thousands of 802.11 wireless devices simultaneously from directly within a WLAN infrastructure.
