I know you can do this on a PC but how do you do it on a router, can you?

    I don't think you can change this in IOS it uses the OpenSSH code and it's implementation. The closet thing you could come up with is how to do a reverse-telnet type situation with ssh.

    "ip ssh port" will do it but the port must be between 2000 and 10000.

    Me being wrong ---> Regular IOS doesn't use OpenSSH. Cisco did their own implementation. Some of their other devices do use OpenSSH however. <--- Me being wrong

    Nope. Plazma is right and I'm wrong icon_redface.gif. Their old SSHv1 implementation is their own but the new SSHv1/SSHv2 implementation is OpenSSH based.

    Its to implement the reverse telnet/ssh feature. It still listens to the regular port 22.

    It should do what you want though still? I just tried it with my router and I can SSH into port 2001 and get the CLI.

    Why do you want to change it anyway?

    Under vty lines the rotary is so you can change the telnet port

    rotary 5 means it will use 3005 for telnet
