NOTE
To configure, monitor, and maintain the local or remote Secure Router 8000 Series network devices,
configure the user interface, user management, and the terminal service.
The user interface provides the logon mechanism, user management guarantees logon security,
and the terminal service provides the logon protocol.
The Secure Router 8000 Series supports the following logon methods:
•
logon through the console port
•
local or remote logon through the AUX port
•
local or remote logon through Telnet or SSH
9.1.2 Telnet terminal services
A
When the number of remote logon users reaches the maximum number of virtual type
terminal (VTY) user interfaces, the system notifies you that all user interfaces are in use and
you cannot use Telnet to log on.
Telnet is an application layer protocol in the TCP/IP protocol suite. It provides remote logon
and a virtual terminal service through the network.
The router provides the following Telnet services:
•
Telnet server: You can run the Telnet client program on a PC to log on to, configure, and
manage the router.
•
Telnet client: You can run the terminal emulation program or the Telnet client program
on a PC to connect with the router. You can use the telnet command to log on to other
routers to configure and manage them. In Figure 9-1, Router A serves as both the Telnet
server and the Telnet client.
