I upgraded a Catalyst 2950 switch and there wasn't enough room so I deleted the flash. The upgraded went well using tftp. It booted up fine. The I0S version includes crypto. But, I can't access switch via web browser or CNA. Port scan shows port 80 0pen. What am I missing?
Here is the flash.

Below is config that is pretty much unconfigured.

I believe that the root of this problem is in the way that you upgraded the 2950. The graphical management interface for this switch is not in the bin file that is the operating image but is in other files in flash associated with the image file. There are two approaches to upgrading these switches - you can upgrade using the tar file which includes the options like the graphical management interface or you can upgrade by copying just the bin file. It looks like you upgraded using the bin file and not the tar file. This results in not having the files in flash that support the graphical management interface. If you want to use a browser or CNA to manage this switch you probably need to do the upgrade over again and use the tar file this time.

Rick,
I used the tar file to up load what is in the current flash.
C2950 EI AND SI IOS CRYPTO AND WEB BASED DEVICE MANAGER
c2950-i6k2l2q4-tar.121-22.EA14.tar
Release Date: 02/NOV/2010
Could it be wrong tar I uploaded? I see HTML in the flash.
Thanks,
Tom

Here is what was part of the original post:
Directory of flash:/
2 -rwx 112 Mar 01 1993 01:00:48 +00:00 info
3 -rwx 3722814 Mar 01 1993 01:02:58 +00:00 c2950-i6k2l2q4-mz.121-22.EA14.bin
If the code upgrade was done using the tar file I would expect to see a directory entry at the top level of flash showing the version information and the bin file (and html etc) within that directory. But here the bin file is at the top level of the flash.
Did you do the upgrade using the archive download command or using a copy tftp flash command?

Rick,
I got it working after adding the lines below. I haven’t determined if it needs them both or just one of them. Thanks for replying to my post though.

Thanks for posting back and telling us that you have fixed the problem. And congratulations on finding the solution.
I would think that the second line would be more important than the first one.
