Yes, I am doing the thing you suggested, I need to check how the Packet
structure to Networks
I can't assign the Packet-Type, even I use "Authentication" and 1, it will

Any guideline about how to assign value for the Struct type defined in
dictionary?

        recv Access-Request {
             subrequest @tacacs::Authentication-Start {
                User-Name := parent.request.User-Name
                User-Password := parent.request.User-Password
                *Packet.Packet-Type := 1*
                tacacs
            }

        }
