Radius for Cisco logout action log.

[epilas]

Hi all,
i have an installation of pfsense version 2.3.1 and FreeRadius 2 package in order to authenticate to Cisco devices. I have managed to complete the appropriate configuration so as to be able to authenticate successfully (or not if a wrong password is supplied) and assign each user the appropriate privilege level.

What i cannot find and i would appreciate any help offered is how to log the LOGOUT action on the freeradius server when the ssh session is terminated. Will i need an SQL server for my accounting info to do so? I cannot find any log parameters on the pfsense that will allow me to achieve this logging action.

Thanks a lot in advance for any help.
