Fast Roaming
Fast roaming, also known as IEEE 802.11r or Fast BSS Transition (FT), allows a client device to roam quickly
in environments implementing the WPA2 Enterprise security, by ensuring that the client device does not need
to re-authenticate to the RADIUS server every time it roams from one access point to another.
Fast transition roaming is an amendment to the IEEE 802.11 standard that permits continuous connectivity
aboard wireless devices in motion, with fast and secure handoffs from an AP to another managed AP in a
seamless manner. In order to ensure voice quality and network security, a portable station must be able to
maintain a secure, low-latency voice call while roaming between APs that are handling other traffic.
This device supports the FBT (Fast BSS Transition) as defined in 802.11r for fast handoff with WPA2
Enterprise security. For Voice over WI-FI Enterprise, only a subset of the features defined in 802.11r are
supported. The fast BSS transition decreases latency during roaming.
FBT is enabled per VAP per radio.
Note
Before you configure FBT on a VAP, be sure to verify that the VAP is configured with WPA2 security,
pre-authentication disabled and MFP disabled.
