The output of Configuration

After the configuration of all devices, the network will be able to authenticate with Cisco WLC WPA2 PSK.

Cisco Wireless LAN Controllers (WLCs) support Wi-Fi Protected Access II (WPA2) Personal (PSK) authentication for wireless clients. WPA2-PSK provides a more secure alternative to the older WPA and WEP security protocols by using stronger encryption and authentication methods. In WPA2-PSK authentication, a shared secret or passphrase is used to authenticate the wireless client to the access point (AP) or WLC. This shared secret is used to generate a Pairwise Master Key (PMK) that creates an encryption key for encrypting data transmitted between the wireless client and the AP/WLC. WPA2-PSK uses a four-way handshake process to establish the encryption key, ensuring secure communication. WPA2-PSK is relatively secure for small-scale wireless networks, but using a shared secret is less secure than unique login credentials. In larger networks, more advanced security protocols such as 802.1X/EAP may be necessary.

We will learn how to set up a fundamental wireless network using WPA2 Pre-Shared Key (PSK) authentication in this tutorial. To employs the topology and configuration that we developed in the session on Cisco WLC fundamental configuration. The physical topology is as follows:

IP Addressing of Components:

There are two VLANs on this network:

• Management VLAN is VLAN 10.
• VLAN 20: A user-accessible wireless network.

Please refer to the table of component IP addresses to configure all devices of the topology given above.
