[USR-TC] port parameters

set switched interface slot:X/mod:Y connection_type Direct_net - Uses the protocol parameter’s setting to create a network (virtual node) connection. Employs user name and password specified in this command. Authentication is done by the network protocol such as PPP. Direct_net does not support the SLIP protocol. If I set connection_type to direct_net how users will be authenticated? As I can get from this description user must be authenticated twice - first with user/pass from interface (this user/pass is only sent to radius, user don't have to know this user/pass) and second by ppp authentication (completed on user site, user has to enter correct user/pass from radius). Am I right?
