5.1 User Management Introduction

This section describes basic concepts of user interfaces and user management.

5.1.1 User Interface

A user interface (UI) enables users to log in to the S7700. Through a user interface, you can
configure the parameters on all physical and logical interfaces that work in asynchronous and
interactive modes. In this manner, you can manage, authenticate, and authorize the login users.

Numbering of User Interfaces
You can number a user interface in the following ways:

describes the types of user interfaces supported by the S7700.
Purpose
Local login through the
console interface
Local or remote login
through Telnet or SSH
Relative numbering
Relative numbering indicates that the interfaces of the same type are numbered. The relative
numbering uniquely specifies a user interface of a specified type.
The format of the relative numbering is: user interface type + number. It must comply with
the following rules:
– Number of the CON interface: console0
– Default number of the VTY: vty0, vty1, vty2, vty3, and vty4
Absolute numbering
The S7700 uniquely specifies the default numbers of 0, 34... 38 for the user interfaces of
CON and VTY. You can enter a specific user interface view by entering any of these
numbers.
Mapping between relative numbering and absolute numbering
Figure 5-1 shows the mapping between relative and absolute numbering of a user interface.

Description
It is a linear interface conforming to the EIA/TIA-232
standard. The type of the interface is DCE. Each main
control board provides a console interface.
It is a virtual interface and indicates a logical terminal
line. When you log in to the S7700 through Telnet,
FTP, or SSH, a VTY connection is set up.
