CCNA® Wireless Study Guide

Chapter 7. Introduction to the Cisco Unified Wireless Network (CUWN)

THE CCNA WIRELESS EXAM TOPICS COVERED IN THIS CHAPTER ARE:

• Install a basic Cisco wireless LAN

  • Describe the basics of the Cisco Unified Wireless Network architecture (Split MAC, LWAPP, stand-alone AP versus controller-based AP, specific hardware examples)

  • Describe the modes of controller-based AP deployment (local, monitor, HREAP, sniffer, rogue detector, bridge)

  • Describe controller-based AP discovery and association (OTAP, DHCP, DNS, Master-Controller, Primary-Secondary-Tertiary, n+1 redundancy)

WLAN Deployment Models

CUWN was brought into this world to address grief-inducing WLAN management issues like these:

• Integrating disparate devices types into your WLAN while making them play nicely and work well together

• Maintaining a consistent security configuration with an ever-increasing number of APs being added into the enterprise

• Monitoring the environment for new sources of interference and redeploying existing devices as necessary

• Properly managing channel allocation to minimize co-channel and adjacent channel interference, while ensuring that enough APs are deployed in areas requiring high capacity
