Chapter 3 Configuring General Router Features
Connecting to and Communicating with the Router
Connecting Through a Terminal Server
A terminal server connection provides a way to remotely access the Console port. It is less expensive to
connect to the router through the Management Ethernet 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 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 connection 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.
To establish a connection through a terminal server, perform the following procedure.
SUMMARY STEPS
1. Install and configure the terminal server.
2. Connect the terminal server to the Console port of the target RSP.
3. Power on the router.
4. Identify the target RSP.
5. telnet access-server-address port
6. Press Enter.
7. Log in to the router.
Step 3 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, use terminal
emulation to communicate with the router. For instructions on using a
terminal emulation program, see its documentation.
Step 4 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.
• The router displays the prompt: Username:
Step 5 Log in to the router. Establishes your access rights for the router management session.
• Type your username and password, as described in the “Logging In to
a Router” section on page 3-5.
• After you log in, the router displays the CLI prompt, which is
described in the “CLI Prompt” section on page 3-6.
