Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper
task IDs.
Use the
transport preferred
command to provide a default transport protocol to use when initiating
outgoing connections. The preferred outgoing transport protocol specified with the
transport preferred
command enables you to initiate an outgoing connection without explicitly specifying the transport
protocol.
The Cisco IOS XR software assumes that any unrecognized command is a hostname and the software
attempts a connection. When the protocol is set to
none
, the system ignores unrecognized commands
entered at the EXEC prompt, and does not attempt a connection.
The default setting, the
transport preferred none
command, prevents errant connection attempts.
Task ID
none
Disables the feature.
ssh
Specifies the Secure Shell (SSH) transport protocol.
telnet
Specifies the Telnet transport protocol.
