Darek,
The port-map command lets you define additional port
#s for the services the router knows about, etc so it
watches these other ports then the default ports
defined in IOS. It doesn't change the port # the
router listens for telnet traffic on.
If you define a port-map for telnet, and do a 'show ip
port-map telnet' they'll be 2 entries. One for port 23
and one for the user-defined. You can't delete the
mapping for 23 either because it is system-defined.
However, the below will let you telnet to port 3001 as
well. Use access-lists/classes to restrict access
further.
