Quick points about Wireless in Cisco SD-Access
In today’s highly mobile and dynamic enterprise environments, wireless has become the primary access medium for a wide range of business-critical devices.
A properly designed and deployed SD Access architecture provides the necessary infrastructure for SD-Access wireless.

SD Access has a number of key advantages for Wireless including:
- Simplifying the Control and Management Plane and Optimizing the Data Plane
- Integrating Policy and Segmentation end to end
- Unified Policy between Wired and Wireless
Key aspects of SD-Access Wireless
- WLC and APs are a part of the fabric site.
- Fabric enabled APs terminate VXLAN directly into the Fabric Edge
- WLC centralized control plane and all the innovative RF features that Cisco has today will be leveraged in SD Access wireless like AP Mgmt, RRM, Mobility
- Seamless roaming and scalability built in. SD Access allows customers to have a wireless solution with a distributed data plane without the complications of spanning VLANs across access switches
- Simplified Guest setup and segmentation without the need for a WLC anchor controller
- Secure Policy based automation and SD Access breaks the dependencies between Policy and network constructs (IP address and VLANS) simplifying the way we can define and implement Policies
- Policy is based on Virtual Networks (VNIs) and Scalable Group Tags (SGTs) and are consistent for both wired and wireless users
- WLC must be physically co-located to the APs or have a guaranteed latency <20 ms between the WLC and APs
- WLCs is physically connected to the Border Node or on a Fusion or Services switch
