In the local switched mode of Cisco FlexConnect, what happens to user traffic?

In the local switched mode of Cisco FlexConnect, user traffic is indeed mapped to a VLAN on the adjacent switch. This mode allows the access point (AP) to switch traffic locally, without needing to send it back to the Wireless LAN Controller (WLC) for processing.

This operation is especially beneficial in scenarios where there may be limited connectivity to the WLC or when low latency is required for local resources. The access point can handle local data traffic while maintaining control and management functions from the WLC. By mapping user traffic to a VLAN on the adjacent switch, it effectively utilizes the local switching capability, optimizing performance and reducing unnecessary traffic across the network.

The mechanism also ensures that even if communication with the WLC is impaired, the local traffic can continue to be handled efficiently, leveraging the VLAN mapping on the local switch. This enhances network resilience and user experience, especially in branch or remote office deployments.
