fast-bss-transition

Enables or disables support for 802.11r Fast-BSS Transition (FT) on the selected WLAN. This feature is disabled by default.

802.11r is an attempt to undo the burden that security and QoS added to the handoff process, and restore it back to an original four message exchange process. The central application for the 802.11r standard is VOIP using mobile phones within wireless Internet networks. 802.11r FT redefines the security key negotiation protocol, allowing parallel processing of negotiation and requests for wireless resources.

Enabling FT standards provides wireless clients fast, secure and seamless transfer from one base station to another, ensuring continuous connectivity.

Supported in the following platforms:

• Access Points — AP505i, AP510i, AP510e, AP560i, AP6522, AP6562, AP7161, AP7502, AP7522, AP7532, AP7562, AP7602, AP7612, AP7622, AP763, AP7662, AP8163, AP8543, AP8533.
• Service Platforms — NX5500, NX7500, NX9500, NX9600, VX9000

Syntax

fast-bss-transition {over-ds}

Parameters

fast-bss-transition {over-ds}

fast-bss-transition over-ds Enables 802.11r FT support on this WLAN over-ds – Optional. Enables 802.11r client roaming over the Distribution System (DS). When enabled, all client communication with the target AP is via the current AP. This communication, carried in FT action frames, is first sent by the client to the current AP, then forwarded to the target AP through the controller.
