9.1 Introduction 

9.1.1 Overview of User Login 

To configure, monitor and maintain the local or remote devices, configure the user interface, 
the user management and the terminal service. 

The user interface provides the login plane. The user management guarantees the login 
security and the terminal service provides the login protocol. 

The product supports the following login methods: 

z

 

Login through the console port 

z

 

Local or remote login through the AUX port 

z

 

Local or remote login through Telnet or SSH 

9.1.2 Telnet Terminal Services 

Telnet Services 

Telnet is an application layer protocol in the TCP/IP protocol suite. It provides remote login 
and a virtual terminal service through the network.   

The router provides the following Telnet services: 

z

 

Telnet server: You can run the Telnet client program on a PC to log in to the router, 
configure and manage it. The router acts as a Telnet server. 

z

 

Telnet client: You can run the terminal emulation program or the Telnet client program 
on a PC to connect with the router. With the 

telnet

 command, you can log in to other 

routers to configure and mange them. As shown in 

Figure 9-1

, Router A serves as both 

the Telnet server and the Telnet client. 

Figure 9-1

 

Telnet client services 

PC

RouterA

 RouterB

Telnet Server

Telnet Session 1

Telnet Session 2

 

 

z

 

Redirection terminal services: You can run the Telnet client program on a PC to log in to 
the router through a specified interface. Then connect with the serial interface devices 
that are connected to the asynchronous interface of the router, as shown in 

Figure 9-2

. 

The typical application is to connect the 8/16-port asynchronous interface of the router 
with multiple devices for their remote configuration and maintenance.
