Cisco rookie here.  I had to swap out a failed router and used the existing config from the old router on the new.  I changed the name of the serial interface to reflect the serial name on the new router.

Everything is working fine on the ethernet interfaces, however the serial says down down.

Here is the config of that interface.

interface Serial0/0/0
