4.2.2.1 Relationship between line and interface
a) Relationship between synchronous interface and VTY line
The virtual terminal line provides a synchronous interface to access to the system. When you connect to the
system through VTY line, you actually connects to a virtual port on an interface. For each synchronous
interface, there can be many virtual ports.
For example, if several Telnets are connecting to an interface (Ethernet or serial interface), you need to do the
following steps for the VTY configuration:
(1) Log in to the line configuration mode.
(2) Configure the terminal parameters.
For VTY configuration, refer to Part 4.2.4 “VTY configuration example”.

Run showline to chek the VTY configuration.
