A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building.
We will follow above topology to configure WLAN using WPA2 PSk, Complete these steps in order to configure a WPA2 PSK in the WLC GUI:
1. Navigate to Configuration > Wireless > WLAN > WLANs, and create a new WLAN:
2. Enable WPA2, and map it to the desired interface:
3. Click the Security tab, check the WPA2 Policy checkbox, and select AES as the WPA2 Encryption. In the Auth Key Mgmt drop-down list, select PSK. Enter the PSK that the client will use in order to connect:
WPA2-PSK Configuration with CLI
This is the procedure to use the command-line interface (CLI) in order to configure DHCP snooping for the VLANs that are used for clients. VLAN20 is used for clients and the pool is configured on the same WLC. The TenGigabitEthernet1/0/1 from the Cisco 5700 WLC is connected to the uplink switch. If the DHCP server is configured on the server beyond the WLC or on an external DHCP server, you must trust DHCP snooping and relay information.
