Rick,

After posting the question, I realized it could be the WIC card. I am using a serial WIC card on the 1720 series router to test the point-to-point configuration on the router with a 2612 router with serial WIC card. The production router has a RJ45 WIC interface. The commands were accepted by the production router.

Thanks.
