crypto key generate rsa error

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.

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.
