I've configured a good number of ISR C11174P routers over the last few months using 16.09.04 and i notice when I copy config over (whether using tftp or just copying from a USB stick) that all interfaces are admin down after a reload.
My configs always have 'no shut' under every interface, but when i reload and so a show ip int brief - they're all down, and it's even changed the startup / running config to say 'shutdown' under the interfaces/
I leave it for five minutes and in MOST cases, the ports magically open up, and the config is restored to say no shut.
Is this a bug? Or just a quirk of these devices?
