21 Wireless LAN configuration

 

This chapter covers

  • Preparing a Cisco WLC for configuration via the GUI
  • The physical ports and logical interfaces of a Cisco WLC
  • Configuring simple wireless LANs with WPA2 PSK authentication

Over the past three chapters, we’ve covered the fundamentals of wireless LANs, starting with the basics of radio frequency (RF) communications and 802.11 standards, various wireless LAN architectures, and the many protocols used to secure communications over the airwaves. In this chapter, we’ll bring it all together and see how to configure basic wireless LANs in the graphical user interface (GUI) of a Cisco wireless LAN controller (WLC). Specifically, we will cover the following CCNA exam topics:

  • 2.7 Describe physical infrastructure connections of WLAN components (AP, WLC, access/trunk ports, and LAG)
  • 2.8 Describe network device management access connections (Telnet, SSH, HTTP, HTTPS, console, TACACS+/RADIUS, and cloud managed)
  • 2.9 Interpret the wireless LAN GUI configuration for client connectivity, such as WLAN creation, security settings, QoS profiles, and advanced WLAN settings
  • 5.10 Configure and verify WLAN within the GUI using WPA2 PSK
