Thanks for this, I have been racking my brain trying to figure out why it could not ping anything. The setup does not set a default route. We are demoing, and this saved me a ton of time.
Hi there, thanks for your question! When configuring a Catalyst 9800, it is important to understand the behavior of VLAN 1 and how it is used in different AP modes. Here are some key points to consider. 1. VLAN 1 Usage: - Local Mode/Flex Central Switching: - Specifying `vlan-name = default` assigns the client to VLAN 1. - Using `vlan-id 1` assigns the client to the wireless management VLAN. - FlexConnect Local Switching Mode: - Specifying `vlan-name = default` assigns the client to VLAN 1. - Using `vlan-id 1` assigns the client to the FlexConnect native VLAN. 2. Default Behavior: - If no VLAN is configured under the policy profile, the WLC assigns `vlan-id 1`, so clients will use the wireless management VLAN in local mode and the AP native VLAN for FlexConnect. 3. Best Practices: - It is generally recommended to avoid using VLAN 1 for client traffic due to potential security and management issues. - Configure a specific VLAN for client traffic by navigating to `Configuration > Tags & Profiles > Policy` and setting the VLAN field under Access Policies. 4. Web GUI Access: - Ensure that the VLAN used for management traffic is properly configured and allowed on the data interfaces. - Verify that the VLANs are allowed in your data interfaces by navigating to `Configuration > Interface > Logical > PortChannel name > General` or `Configuration > Interface > Ethernet > Interface Name > General`. We hope this information helps, and please let us know if you're still having trouble. Thanks!

I have been working on those controllers for 3 years on différent versions, i discover New bugs every Time ! Really not as fiable as 3504 or 5520
this is such a great video. I did not need to call support anymore I could do this on my own, pretty easy to follow.
Thanks!
What vlan did you use? I keep.getting stuck with vlan1 to let me webgui
