5.1.2 User management
When a router is powered on for the first time, the user name and password are not configured.
As a result, any user can configure the router by connecting a PC through the console port.
A remote user can access the router through Telnet if the router is configured with the IP
address of the Routing Process Unit (RPU) or that of the interface board. The remote user
accesses the network by establishing a Point-to-Point Protocol (PPP) connection with the
router.
Configure the user name and password for the router to ensure network security and to
improve user management.
User classification
Users of a router are classified as follows, based on the available services:
• HyperTerminal users: Access the router through the console port or the AUX port.
• Telnet users: Access the router through Telnet.
• File Transfer Protocol (FTP) users: Establish FTP connections with the router to transfer
files.
• Point-to-Point Protocol (PPP) users: Establish PPP connections (such as dialing and
PPPoA) with the router to access the network.
• Secure Shell (SSH) users: Establish SSH connections with the router to access the
network.
User level
The system provides hierarchical management of HyperTerminal users and Telnet users.
Logon users have the same 16 levels as commands. They are marked from 0 to15. The higher
the mark, the higher the priority.
