AGS+ IOS upgrade

Discussion in 'Cisco' started by Skylar Thompson, Dec 27, 2004.

  1. I've recently brought an old Cisco AGS+ router on-line. It's running IOS
    10 right now, and I'm trying to upgrade it to something a little less
    ancient. According to Cisco's web site, IOS 11.0 is the last version of IOS
    to support the AGS+, so I downloaded that image (gs3-k-mz.110-22a.bin).

    I tried copying it over from a TFTP server with the "copy tftp flash"
    command, and that worked. I then used the "boot system flash" configuration
    directive to tell it to load the gs3-k-mz.110-22a.bin file. When I
    restarted the router, though, it still came up with IOS 10. What am I doing

  2. As far as I can recall the newest 11.0.xx release only works with
    special controller boards and enough memory, check that, should be in
    the release notes.

  3. First thing, does your AGS+ have flash in it? Or is it EPROM? The
    Flash expansion card gets installed sitting ontop of the card cage,
    take off the front and see if you can see something sitting up there
    on the screw posts.

    Other than that, you do have to the latest controller installed,
    and lots of other little restrictions here and there, but since an
    AGS+ with Flash being sold online isn't the most common, I'd start
    looking there to see if you even have the option installed.

  4. You actually need to change the physical jumpers on the configuration
    register (on the CSC/3 or CSC/4 processor card).

    The rightmost jumper is likely set (boot from ROM). You need to move it one
    to the left to tell it to boot from the net, which invokes the logic to look
    for the flash card.

    This is the genesis of the obscure "config-register" command that persists
    even in the modernest of IOS. There actually was a jumper bank on the
    oldest routers.


    And the current config register definitions

  5. It looks like this is the ticket. I'll get someone over there to move the
    jumper. Thanks!
