Can somebody help me find this IOS Image file for a 2811 Router: c2800nm-adventerprisek9-mz.153-3.XB12.bin

It is not available from the Cisco website, but I know that it is out there.

Can somebody help?




  • Thank you for your reply.

    But actually, it was never available!

    I know that because I work with 2800's and I've been checking the Cisco website almost every day for the last 5 Years and I have never seen IOS version 15.3.3

    Frankly I have no idea where IOS 15.3.3. came from, but I know it is out there.

    The Cisco website only has version 15.1.4M  There is simply nothing beyond 15.1.

    But recently I bought an 1841 Router that came with IOS 15.3.3 loaded on it!

    That was a BIG surprise for me, because the Cisco website also has IOS 15.1 for 1841's.

    So I started looking for IOS 153-3.XB12.bin and I found multiple references to it in the IEOC Blog.

    That's why I posted a message.

    In a Blog Post Brian McGahan wrote the following about this IOS:

    I haven’t used the 15.3 release extensively, but it seems to work. I would run the 15.3 and then if you have problems fallback to 15.1T.

    Just in case, this is the Link to this Post:  http://blog.ine.com/2014/05/13/ines-ccie-rs-v5-hardware-topology/

    In any case, the point is that it is out there, so I'm hoping somebody can help me find it.

    If It is not available from the Cisco website, there must be a reason for it?  maybe image replaced by next version ?

  • I did some more research about this IOS version and I found out that this image file was created ONLY for Training purposes; not for commercial use.

    That's why it was never available for download from the Cisco site.

    So I guess that only large training facilities (like INE) have access this image file!

    Therefore, I'm still hoping that somebody can help me find it.
