I would like to disable the telnet access to my router and switches and replace it with SSH. What is the requirement, and what are the command to set it up?

First you need a IOS image that supports SSH on your router.

Then you need some terminal application with the same support.

To generate keys (enter in global): cry key generate rsa

Then to limit the access vty with only SSH (enter in line vty): transport input ssh

Then there are some optional commands to tweak SSH as you desire.
