    FYI to all-
    when ordering a new router or switch OR upgrading one of the newer Cisco devices, the Cisco IOS has been renamed and repackaged.

    In the past, the IOS file would look like this-
    c2600-is-mz.120-7.T

    The problem with that is knowing what features are contained in the “is” version.

    The new IOS file would look like this-
    c3845-ipbase-mz.123-11.T7.bin

    This began in IOS 12.3

    I see that this applies to these routers- 1700, 2600XM, 2691, 3700, 2800, 3800 but not the 2600 and 3600 series routers.

    Here is the link to the Cisco IOS packaging website that explains this in more detail. There is also a powerpoint presentation and video-

    I have attached a graphic showing the new IOS versions.

    Happy Upgrading!
