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:

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

    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:

    % Invalid input detected at '^' marker.
