Hi,

First you must make sure that you are using an IOS that supports SSH, please use the Feature Navigator:

http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp

Here you are a simple example and please check the below document for more details:

username test password test

hostname Routerx

ip domain-name cisco.com

crypto key generate rsa

line vty 0 15

transport input ssh

login local

Configuring Secure Shell

Is there a 'best practice' as related to running ssh instead of telnet on switches such as the 2950? I have put the crypto image on one of my switches to test but it obviously uses more memory.

In absolute terms SSH is more secure than Telnet and for most people that makes it better and for some it is perhaps a "best practice". But you are correct that it requires a crypto image and for many versions that does involve more memory.

So in your case which is more important: better security or minimizing memory requirements?
