Latest IOS for 1720 with ENET WIC

    I'm getting lost going round and round in circles. The Cisco software
    configurator doesn't seem to support the 1720 series.

    The current IOS is c1700-o3y-mz.121-5.yb4. I thought that
    c1700-o3y-mz.122-23a would provide the same options, but when the second
    file is installed the router boots correctly but there is no Ethernet0
    device. How do I identify which IOS supports an ENET WIC?

    thanks

    Mark

  2. Try have look at this:

    The requirement is 12.2(2)XJ or later.

    Hello guys,

    I am having the same issue a few posts ago. I have version IOS (tm) C1700
    Software (C1700-SY-M), Version 12.2(16a), RELEASE SOFTWARE
    (fc2)
    and I can't get my Enet to work either. Isn't 12.2(16) newer than 12.2(4)

    I had a similar problem, and after some research at Cisco and some help
    from this group found that c1700-y-mz.122-11.T10.bin is the one you want.
    It actually supports two WIC-1ENET cards. If you need additional features,
    there should be other variants of the same base code.

  5. Cisco doesn't have a linear train of code release. It branches all the
    time, which is why when you want to search for features and supported
    items, you really need to get familure with Feature Navigator big time.
    (www.cisco.com/go/fn).

    In this case, you are running the train 12.2(16a) with no letters, but the
    requirement is to be running the XJ branch train.

    No, 12.2(16a) doesn't automaticaly include anything in the XJ train.
    But 12.3(x) probably does, but you'd have to check the FN.

    Whenever Cisco introduces new features, or new hardware, they
    generally branch off a new train to support the new whatever, while
    they continue to fix bugs on the other trains. This leads to much more
    stable code releases overall, as bugs introduced by new features/new hardware
    can be fixed and isolated in their own trains, while the mainline
    trains keep stable.

    Thus, 12.2(16a) while might be newer than 12.2(2)XJ, doesn't have the
    feature sets built into the XJ train. They are different code
    branches, and if you need an XJ branch, then having 12.2(16a) is not
    sufficient.

    For the extreme opposite case, look at companies like Ascend. Their
    code release schedule was extremely linear. Every new major release had a
    new feature or new hardware support. Every new release had major bugs
    that didn't necessarily get fixed because they were too busy putting
    in new features. You'd have to go up and down the code tree
    trying out releases to live with the bugs that release had and
    minimize the bugs in the feature sets that you really wanted to use.
