Configure Virtual Terminal Lines for Remote Console Access

Virtual terminal (vty) lines are used to allow remote access to the router. This section shows you how to
configure the virtual terminal lines with a password, so that only authorized users can remotely access
the router.
By default, the router has five virtual terminal lines. However, you can create additional virtual terminal
lines. See the Cisco IOS XE Dial Technologies Configuration Guide at
http://www.cisco.com/en/US/docs/ios/dial/configuration/guide/2_xe/dia_2_xe_book.html.
