Network Tip No. 35: Stopping the router from crazy output

Stopping the router from crazy output...

An annoying problem output everytime you mistype a command and the router thinks you just typed a hostname. For example:

  Router#shwo
  Translating "shwo"...domain server (10.1.1.1)
  % Unknown command or computer name, or unable to find computer address
  Router#

The way to handle this is to change the preferred transport method:

  ! Console port
  line con 0
      transport preferred none
  ! VTY Ports
  line vty 0 5
      transport preferred none

The output shows the lack of a failed connection based on our mistyped keyword:

  Router#shwo
      ^
  % Invalid input detected at '^' marker.
