Change telnet port on cisco router?

Is there a way you can change the port that telnet is listening on on a cisco router prefferably 3660 or anyone really just want to know...I know you can implement ssh over 22 but can you configure any other ports???

Thanks, kenny.

Yes, it is possible because I've done it before, but the command escapes me. If only I had my SNRS book...

I'd just drop telnet all together and set up SSH, which uses port 22.

ip ssh time-out 60
ip ssh authentication-retries 3
!
line vty 0 15
transport input SSH

It doesn't answer your question directly, but it will definitely get around port 23!

Is it possible to run ssh on a different port than 22 then?

Use the 'rotary" command in line config mode to force the router to listen on a different port
