Hi Dwane, what you mean is that you want to first 2 connections via telnet or SSH to be authenticated via the LOCAL database and the subsequent connections to be authenticated via a RADIUS server? I think this can be done only on devices that use the line vty connections.
Since the line VTY numbers go from 0 to 15, you can configure each line separately unsing for example something like this:
aaa authentication login LINE1_2 local
aaa authenticaiton login LINE3_16 group radius
line vty 0
login authentication LINE1_2
line vty 1
login authentication LINE1_2
line vty 2 15
login authentication LINE3_16
The way this works is that when you initially telnet/SSH to your router, it will be connected to the line vty 0 line using the LOCAL authentication same applies to line 1, once you have used both line 0 and line 1 and you try to use line 2 those will be placed under line vty 2 which is authenticating via a radius.
Note radius authentication will only apply or kick in if the the previous lines are used.
