It's also worth mentioning that most older routers didn't ship with the encrypting feature set because of US cryptographic export laws. Cisco made it where it was up to the customer to upgrade the router once they received it. New routers are subject to the newer laws which don't have those limitations and as a result usually do ship with the encrypting feature set.

If the "crypto" command is not present, then your IOS does not contain the encrypting feature set. Run "show version" or "show flash:" and look at the file name of your IOS file. If your IOS has the encrypting feature set you will see "K8" or "K9" in the file name. If that is missing, you will need to upgrade your IOS. Fortunately Cisco does not charge for that as long as your system is covered by SmartNet.

I have a 2621 cisco router but when I go to the configuration mode and type crypto ? it says "unrecognized command". The router is running 12.1(6). Do I need to upgrade the IOS software? Please help.

Nice tutorial!

I like when a tutorial shows you how to do it especially when you are a beginner. I am an online student who is majoring in Computer networking and it is hard. We use a labsim program to do our work but I am having a hard time with how to create an access-list. The assignment is to Restrict Telnet and SSH Access by creating an access-list. Can you do a tutorial for this.
