Customizing the Web Authentication Login Screen

Using the CLI to Configure DHCP

Follow these steps to use the CLI to configure DHCP.

Step 1 In the CLI, enter show wlan to verify whether you have a valid DHCP server assigned to the WLAN. If you have no DHCP server assigned to the WLAN, continue with Step 2. Otherwise, continue with Step 4.

Step 2 If necessary, use these commands:

•config wlan disable wlan-id

•config wlan dhcp_server wlan-id dhcp-ip-address

•config wlan enable wlan-id

In these commands, wlan-id= 1 through 16 and dhcp-ip-address= DHCP server IP Address. Step 3 Enter show wlan to verify that you have a DHCP server assigned to the WLAN.

Step 4 Enter ping dhcp-ip-addressto verify that the WLAN can communicate with the DHCP server.

Customizing the Web Authentication Login Screen

Web authentication is a Layer 3 security feature that causes the controller to not allow IP traffic (except DHCP-related packets) from a particular client until that client has correctly supplied a valid username and password. When you use web authentication to authenticate clients, you must define usernames and passwords for each client, and when clients attempt to join the wireless LAN, they must enter a valid username and password when prompted by a login window. These sections describe the default web authentication operation and how to customize the Web Authentication Login window.
