If you have management traffic that isn't on the same subnet as the Big-IP management interface, it will typically not use the management default route to get there - it will use a route as defined in the data path of the system (something under list ltm route, or Network, Routes in the GUI).

 

For things you want to force to go out the management interface, you can use the create sys management-route command in tmsh.

 

Is your RADIUS server on the same subnet as the management interface? I think there are some exceptions to the rule about not using the default gateway of the management interface, and RADIUS could be one of those.
