Cisco Command Accounting..? [Virus checked]

Hi, sorry if I come up with this question here, since it is not a problem of freeradius by itself, but maybe someone could help me I want to use freeradius also for authenticating our network-admins when they login to our network-devices (e.g. Cisco boxes) Authentication/Authorizsation works fine Accounting (Start/Stop of Login Session) also what I want to do in addition is to log admins activities (commands they enter on the devices) I know that this works for TACACS+, but it doesnt seem to when using Radius-Protocol I've searched already this mailing-list and the web, and it seems that Cisco does not support this feature? Has anyone experience with this or could give me a hint on how to accomplish this? thank you thomas
