Chapter4 Configuring General Router Features
Connecting and Communicating with the Router
Establishing a Connection Through a Terminal Server
A terminal server connection provides a way to access the Console port from a remote location. It is less
expensive to connect to the router through the Management Ethern et interface (because you do not have
the additional cost of a terminal server). However, if you need to perform tasks that require Console port
access from a remote location, a terminal server is the best connection method.
The procedure for connecting to the router through a terminal server is similar to the procedure for
directly connecting through the Console port. For both connection types, the physical co nnection takes
place through the Console port. The difference is that the terminal server connects directly to the Console
port, and you must use a Telnet session to establish communications through the terminal server to the
router.
Step3 Start the terminal emulation program. (Optional) Prepares a computer for router communications.
•The step is not required if you are connecting through a
terminal.
•Terminals send keystrokes to and receive characters
from another device. If you connect a computer to the
Console port, you must use a terminal emulation
program to communicate with the router. For
instructions on using the terminal emulation program,
see the documentation for that program.
Step4 Press Enter. Initiates communication with the router.
•If no text or router prompt appears when you connect to
the Console port, press Enter to initiate
communications.
•If no text appears when you press Enter and the router
has been started recently, give the router more time to
complete the initial boot procedure, then press Enter.
•If the router has no configuration, the router displays
the prompt: Enter root-system username:. If a
standalone router is starting up for the first time, see
Chapter 2, “Bringing Up the Cisco IOS XR Software on
a Standalone Router.” If a multishelf system is starting
up for the first time, see Chapter3, “Bringing Up the
Cisco IOS XR Software on a Multishelf System.”
•If the router has been configured, the router displays the
prompt: Username:
Step5 Log in to the router. Establishes your access rights for the router management
session.
•Enter your username and password, as described in the
“Logging In to a Router or an SDR” section on
page4-11.
•After you log in, the router displays the CLI prompt,
which is described in the “CLI Prompt” section on
page4-12.
