crypto key generate rsa error

BadFish

Good evening all,
I am working on a lab and am trying to configure ssh on a 2950 switch ios version 12.1(11).
I have created a local user and password however when I try and generate the rsa I get this error:

Cisco(config)#crypto key generate rsa
               ^
% Invalid input detected at '^' marker.

Cisco(config)#

any suggestions?

BadFish,

What is the name of the image you're using? I would check the Cisco Feature Navigator to be sure that the IOS you're using supports the command. It appears that the IOS you're using doesn't. Perform a "show version" to determine your IOS. I hope this helps.

What's the actual image name from the show version command (assuming someone didn't rename it)?

Is it the crypto image or the non-crypto image?

Chances are the image doesn't support the crypto functions. I ran into this with my 1721 router and had the same issue until I figured out that version of my IOS didn't support it. For some reason they decided they wanted to load all my routers with the IP-base IOS.

As far as I know 2950s do not support SSH. On my last job we switched out all of our 2950s for newer switches in order to move completely to SSH.

Login to the Cisco website and grab a k image.

Is there a way for me to get an image without having to pay for support? :

IOS images for basic switches like a 2950 are free to download without a SMARTnet contract. You just need to register a user on cisco.com.
