Patrice Issue "show controller serial <> " for serial interfaces . The end which is a DCE ; you should apply "clock rate <> " under that only Other end (DTE) ; should not hve clock rate command.
Goes withoult saying that please check the physical media as well This is a serial .. as soon as it detects a cable on its connector port ; it will go up .. so even if you connect a open-ended cable ..... it will still say up|down . If it doesnt solve prob .. lemme know which WIC card is this on what router .. also what cable are you using ?
