  • 1. Cisco WCS Administration Monitoring the Network with Cisco WCS

2. Initial Screen Home 3. Home > Edit Tabs 4. Home > Edit Content 5. Home > Personalized Tab 6. The Monitor Menu 7. The Alarm Dashboard

  • Refreshes every 15 seconds
    • Four levels:
      • Clear = no alarm
      • Yellow= minor alarm
      • Orange = major alarm
      • Red = critical alarm

8. Monitor > Controllers 9. 10. Monitor > Access Points 11. 12. Monitor > Clients 13. 14. Associated Clients (vs. Time) 15. Monitor > Clients > Troubleshoot 16. Monitor > Security 17. 18. Monitor > Security Rogues 19. Monitor > Security Miscellaneous 20. Monitor > Alarms 21. Monitor > Events 22. Cisco WCS Location

    • Ability to locate any 802.11 active device
    • Accuracy:
      • 90% to within 10 meters, 50% to within 5 meters
      • Depends on environment characteristics and calibration
    • On demand, one device with Cisco WCS alone
    • Up to 2500 devices with Cisco Location Appliance
      • 30-day history (configurable)
    • Can identify and locate non-802.11 interference with Spectrum Intelligence sensor

23. Location Tracking Methods

  • RF Closest AP
    • Pro: Simple, with no new technology requirement
    • Con: Limited accuracy, since an AP can easily cover several thousand square feet
  • RF Triangulation
    • Pro: More accurate than a single RF RSSI
    • Con:Limited accuracy; does not account for effects of building material which may cause reflection, attenuation or multipath
  • RF Fingerprinting
    • Pro: GPS-like accuracy
    • Con: More comprehensive (requires RF prediction tools)

24. Location Tracking Using Closest AP 25. Location Tracking Using Triangulation 26. Location Tracking Using RF Fingerprinting

    • RF fingerprinting traces signal strength for every signal heard by a Cisco AP in the network, which allows accounting for reflection and multipath.
    • Then a RF fingerprint is created from every point on the coverage map, which allows Cisco WCS to accurately place an icon and create a probability color grid.

27. Cisco WCS Location Without Appliance 28. Cisco WCS Location with Appliance

  • Cisco WCS with Location and Location Appliance accuracy
    • 90% to within 10 meters, and 50% to within 5 meters

29. Searching for a Device 30. Search > Clients 31. Search > Clients (Cont.) 32. Recent/Present Map 33. Summary

    • The home page for each user consists of tabs that can be personalized.
    • Cisco WCS also has a Monitor menu, where each type of device can be verified.
    • An alarm dashboard can give an alert in case of an unusual event.
    • Controllers can be monitored and managed.
    • APs can be verified individually or through a network summary.
    • Detailed information about clients can be displayed.

34. Summary (Cont.)

    • Each security-related event can be checked before you take further action.
    • Cisco WCS has a summary page where alarms are grouped and displayed, even when the alarm-triggering event is not in the network anymore.
    • All events can be accessed and assigned to different administrative users, depending on their nature.
    • Cisco WCS has a location capability to identify the position on a map of any wireless device.
