importing 802.1x wireless profile using networksetup

Hi,

I am using MAC OS X version 10.6.4. I have created 802.1x wireless security profile of PEAP security in airport utility. I have exported the profile using the command

>networksetup -export8021xProfiles AirPort pea.xml yes

pea.xml is successfully created. I delete the profile from the AirPort utility and issued the command

>networksetup -import8021xProfiles AirPort pea.xml

I could not see the no wireless profiles being created in 'AirPort Utility'.

Please tell me where I went wrong.

thanks in advance
