Usage guidelines
FT minimizes the delay when a client roams from a BSS to another BSS within the same ESS. During 802.11r FT, a client needs to exchange messages with the target AP. FT provides two message exchanging methods.
Enable FT only when the service template is disabled.
If FT is enabled, you must disable WPA IE and local authentication, and make sure the CCMP cipher suite is used. To disable WPA IE, use the undo security-ie wpa command. For more information about the command, see WLAN Security Command Reference.
Examples
# Enable FT.
<Sysname> system-view
[Sysname] wlan service-template st
