The default preamble length value is short. This command does not 
apply to 802.11a radios.

To change the preamble length advertised by 802.11b/g radios, use the 
following command:

set radio-profile name preamble-length {long | short}

To configure 802.11b/g radios that use the radio profile rp_long to 
advertise support for long preambles instead of short preambles, type the 
following command:

WX1200# set radio-profile rp_long preamble-length long
success: change accepted.

To reset a radio profile parameter to its default value, use the following 
command:

clear radio-profile name parameter

The parameter can be one of the radio profile parameters listed in 
Table 12 on page 209. 

All radios that use this profile must be disabled before you can delete the 
profile. If you specify a parameter, the setting for the parameter is reset 
to its default value. The settings of the other parameters are unchanged 
and the radio profile remains in the configuration. If you do not specify a 
parameter, the entire radio profile is deleted from the configuration.

To disable the radios that are using radio profile rp1 and reset the 
beaconed-ssid parameter to its default value, type the following 
commands:

WX1200# set radio-profile rp1 mode disable
WX1200# clear radio-profile rp1 beaconed-ssid
success: change accepted.

To remove a radio profile, use the following command:

clear radio-profile name
