    cisco router

    hi all i have an old cisco 2600 router that i'm currently playing with, i'm not sure the exact ios buts its 12 something i think, the problem is when i use the show interfaces command it returns no results at all, almost as if the serial and ethernet slots are not there? has anyone come across anything similar? am i using the right command on this early version of the ios? is there anywhere that will tell me what ios i need?

    thanks in advance as always.

    No, i haven't come across that problem before

    if the IOS version is IOS 12.x it's not terribly old.....

    can you get a show run, if so what are the results ?

    Hi,

    Try

    show ip int brief

    at the priviliage exec mode (i.e. when you are at # prompt)

    This should show you the interface status and weather its down or up.

    Show controllers might also be worth a try

    You could also try reseating the WICs if its a modular one.

    i suspect you've got dodgy hardware....you could try doing what sparky suggested and resintall the IOS,

    but tbh if it's something you got off ebay and if it's the earlier non XM version of the 2600 series my hunch is you've got faulty hardware.

    Don't bin in yet, Keep persisting and check the cisco troublshooting docs. You could go into rommon and mess about with the config-registers, but you're better off focusing you're troubleshooting on IOS reinstall.

    The serial interface is modular and i have checked that and all is ok but still won't show up? the ethernet is onboard.
    I suspect a dody IOS if i'm honest but as i understand you can't just download them if you don't have some sort of contract and as i came across the router second hand thats not an option.
