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
