    hey, i have a few things that needs to be clarified. I know about network layer 1, layer 2 and layer 3 error causes but in real life, you encounter so many different things. Moreover, if case is the serial interface,
    i can count the possible issues such as DCE or clocking problem, encapsulation problem, NIC problem etc for
    interface status "up" , line protocol "down" and cable problem, device is off, for "down", "down"

    However, i wanna ask about Cisco 877 modem connected through fastethernet interfaces to the Cisco
    1131 WAPs. If we mention fasthethernet what should i think about

    1) fastethernet is up , line protocol is down ? and 2) fastethernet is down, line protocol is down?

    for the first, is there any WAPs currently connected? Or , once it was connected but not connected now?

    for the second, is it the same as serial interfaces?

    If the two devices are connected on Fast Ethernet ports, why would you treat the line/link up/down alerts any differenet to if it was just a PC connected to a switch?
