Declare Client VLANs
Before you start any configuration, you need to add the needed VLANs (VLANs where the wireless clients are assigned). Step 1. Navigate to Configuration > Layer2 > VLAN > VLAN > + Add. Step 2. Enter the needed information. Repeat steps 1 and 2 for all the needed VLANs. Once done, you can continue to step 3. Step 3. Verify the VLANs are allowed in your data interfaces. If you are using port channels, navigate to Configuration > Interface > Logical > PortChannel name > General. If you see it con...
Wizard Based Configuration - Recommended for New 9800 WLC Deployments
For Catalyst 9800 WLCs installation, you can use configuration wizards made available to guide you through the configuration process. If you need to use RADIUS servers on your deployment, you can use the AAA Wizard first and then choose between the Basic or Advanced Wireless Setup. If you do not use RADIUS servers on your deployment, you can go directly to either Basic or Advanced Wireless Setup.
