What is fast secure roaming (FSR)?
A. FSR is one of the features that WDS offers. FSR is supported by Cisco Aironet 1200 and 1100 Series APs in conjunction with Cisco client devices or Cisco-compatible client devices. With FSR, authenticated client devices can roam securely at Layer 2 (L2) from one AP to another without any perceptible delay during re-association. FSR supports latency-sensitive applications, such as: • Wireless Voice over IP (VoIP) • Enterprise resource planning (ERP) • Citrix-based solutions WDS provides fast, secure handoff services to APs, without the drop of connections. The services are for applications, such as voice, that require roaming times that are less than 150 ms.
