Overview Of User Login; Logging In To The Devices Through The Console Port; Establishing The Configuration Task - Huawei AR2200 Series Configuration Manual

Huawei AR2200 Series Enterprise Routers
Configuration Guide - Basic Configuration

5.1 Overview of User Login

Users can manage and maintain the router only after logging in to the router. Users can log in
to the router by using the console port, Telnet, or STelnet (SSH Telnet).
To configure, monitor, and maintain the local or remote network devices running AR2200, you
need to configure the user interface, the user management, and the terminal service.
The user interface provides a login plane. The user management guarantees the login security
and the terminal service provides related processes of login protocol.
The AR2200 supports the following login methods:

5.2 Logging in to the Devices Through the Console Port

When a user needs to configure the router that is powered on for the first time or locally maintain
the router, the user can log in to the router through a console port.

5.2.1 Establishing the Configuration Task

Before configuring user login through a console port, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the required data. This will help
you complete the configuration task quickly and accurately.

Login through the console port
Local or remote login through Telnet or STelnet
Application
Users log in to the router through the console port to configure the router
locally. Login through the console port is required when the router is
powered on for the first time.
Users log in to the router by using Telnet for local and remote maintenance.
Telnet helps users maintain remote devices but brings security threats.
SSH (STelnet) provides security protection for users logging in to the
router to maintain the router locally or remotely.
NOTE
Logins by using Telnet bring security risks because no secure authentication mechanism is available and
data is transmitted by using TCP in plain text mode. Unlike Telnet, SSH guarantees secure data transmission
on a conventional insecure network by authenticating the client and encrypting data in both directions. SSH
supports security Telnet (STelnet).
For detailed information about SSH, see the AR2200 Feature Description - Basic Configurations.
