Configures
The transport protocol
Default
Output and preferred, telnet
; input,
none
Description
This command specifies the transport protocol the router should use.
input
specifies the protocol to use for incoming
connections on a line; output
is for output
connections on a line; and preferred
is the
transport protocol to use when the user does not specify one.
Using the command transport
preferred
none
helps to prevent
typos at the command line from causing a bogus DNS lookup. (With the
default output setting, a mistyped command is frequently interpreted
as a hostname for the telnet, initializing a DNS lookup.)
The protocol
parameter specifies which
protocol to use; possible values are given in Table 15-23.
