No SSH Capability on 3550

I downloaded a new IOS that said IP base w/ crypto because I was unable to enable ssh on the old IOS.  However when I try to run the crypto key generate command I get the invalid input message.

I did a show ver:

You probably downloaded the wrong image. There are images "w/o crypto" and images where crypto is not mentioned. You need the later ones, these have a filename that includes "k9" which stands for crypto-support.

Thanks.

I scrolled down below the image I had originally downloaded and found the K9 image.  I loaded it and ssh works now.

Hi, 

I just recently purchased x2 Cisco 3550 switches to aid in my ICND1 + 2 studies and have discovered that the current IOS version they are running isn't the version that supports "Crypto Key Generate".

Is it possible to obtain "c3550-ipbasek9-mz.122-44.SE6.bin"?

Any help in this mater would be greatly appreciated.

For SSH, you need a k9 image, and you have not installed that. U have
