port-name

    Specifies the name of the application port or the dedicated port
    that you want to delete. An application port connects to a remote
    device on a terminal server, whereas a dedicated port connects to
    a special service.

    Use the SHOW PORT command for a list of the application ports and
    the dedicated ports that are defined for your service node. You
    cannot use the DELETE PORT command to delete an interactive or
    forward LAT port.
