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.

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 same as using the transport preferred command with the none keyword, prevents errant connection attempts.

When creating or modifying vty pools, follow these usage guidelines:

• Before creating or modifying the vty pools, enable the Telnet server using the telnet server command in global configuration mode. See Cisco IOS XR IP Addresses and Services Configuration Guide for the Cisco XR 12000 Series Router and Cisco IOS XR IP Addresses and Services Command Reference for the Cisco XR 12000 Series Router for more information.
• The vty range for the default vty pool must start at vty 0 and must contain a minimum of five vtys.
• The vty range from 0 through 99 can reference the default vty pool.
• The vty range from 5 through 99 can reference a user-defined vty pool.
• The vty range from 100 is reserved for the embedded event manager vty pool.
• The vty range for embedded event manager vty pools must start at vty 100 and must contain a minimum of six vtys.
• A vty can be a member of only one vty pool. A vty pool configuration fails if the vty pool includes a vty that is already in another pool.

If you attempt to remove an active vty from the active vty pool when configuring a vty pool, the configuration for that vty pool fails.
