Serial Port Not Routing

    I have two 2501's hooked up back to back via the serial connections. Problem
    is on one port the interface goes to an up/down status and does not work.
    The same exact config on the other serial interface stays in the up/up mode
    and can route. It's not the cable, clocking or the configuration. Is my IOS
    corrupt?

    Thanks

    Do you have "no keepalive" configured on the one that stays up/up?

    No, 'no keepalives' are not on any of the interfaces.
    Should I post the 'sh int serial x' config?

    IP addresses were removed from the old Interface prior to adding them to the
    new one. Clock is set at 56000 on the both R3 Interfaces.

    Thanks,

    Post the config files for both Serial Interfaces in question.
    Make sure you only have the clock rate on the DCE side, the other side does
    not get the command.

    Thank you for your offering of help but I had to tear down the lab over the
    weekend in preperation of a move shortly.
    I will repost once I am settled.
