Did you assign an IP to that interface ?

You mentioned you have a back-to-back serial connection, did you configure clocking on the DCE end ?

The down/down issue may be cable related but I'm concerned about the original message "Internet protocol processing disabled".


Are you still experiencing the message after entering an IP on the interface ?


Can you post the router's config along with the show version output ?
