Error trying to use Crypto Command on 2950 Switches- NEED HELP BADLY

Hi, I have three switches in my home CCNA Lab, one is a L3 3550 which supports SSH fine. I am having big issues with the 2x 2950 switches, I upgraded the IOS to c2950-i6k2l2q4-mz.121-22.EA14 which according t Cicso.com is image that supports SSH.

When I go into global config and try to generate the keys by typing crypto ? it doesn't allow me to use that command, says not recognized

does anyone know why this is happening? as its driving me crazy, really need some help.
If cannot get SSH working on the 2950's I may as well get two more 3550's
Thanks,
Rodney FL USA.

I'd start by confirming that you're running the IOS version that you think you are. Can you copy/paste a 'show version'?

Hmm, I can do this command in packet tracer on a 2950 no problem.

You'll need a different IOS - I had the same issue when I first got my 2950's. Don't remember exactly which version you need, but a quick google search would probably tell you...

edit - I used c2950-i6k2l2q4-mz.121-22.EA13, so I'm assuming 14 should also be good. As volume suggested, did you verify the version that your switch is running after the upgrade??

I am having the same issue as the original poster. I am using some 2950's as in home lab switches and I have updated the IOS to c2950-i6k2l2q4-mz.121-22.EA13.bin, however I still don't have access to the crypto commands in global config. What am I doing wrong here?

clarson

have you set a domain name for the switch? what is the model of the switch (c/g/t)?

As Volume said, sounds like you have the wrong IOS version. Big giveaway if you are trying to type the command and it's not even available. Try a show version and do some googling to check its supported

Any image that supports SSH will have a "k9" in it.
