Login method
Default state
By default, you cannot log in to a device through an network
management station (NMS). To do so, log in to the device through the
console port, and complete the following configuration:
z
Configure the IP address of the interface, and make sure the
device and the NMS can reach each other (by default, your device
does not have an IP address.).
z
Configure SNMP basic parameters.
User Interface Overview
User interface (also called line) allows you to manage and monitor sessions between the terminal and
device when you log in to the device through the console port, AUX port, or an asynchronous serial
interface directly, or through Telnet or SSH.
Asynchronous serial interfaces include the following two types:
z
Synchronous/asynchronous serial interface operating in asynchronous mode, whose interface
index begins with
Serial
.
z
Dedicated asynchronous serial interface, whose interface index begins with
Async
.
One user interface corresponds to one user interface view where you can configure a set of parameters,
such as whether to authenticate users at login, whether to redirect the requests to another device, and
the user privilege level after login. When the user logs in through a user interface, the parameters set
for the user interface apply.
At present, the system supports the following four CLI configuration methods:
z
Local configuration via the console port
z
Local/Remote configuration via the AUX port (Auxiliary port)
z
Local/Remote configuration via the asynchronous serial port
z
Local/Remote configuration through Telnet or SSH
The four methods correspond to the following four user interfaces.
z
Console user interface: Used to manage and monitor users that log in via the console port. The
type of the console port is EIA/TIA-232 DCE.
z
AUX user interface: Used to manage and monitor users that log in via the AUX port. The type of the
AUX port is EIA/TIA-232 DTE. The port is usually used for modem dialup access.
z
TTY (true type terminal) user interface: Used to manage and monitor users that log in via TTY,
namely, via an asynchronous serial port.
z
VTY (virtual type terminal) user interface: Used to manage and monitor users that log in via VTY. A
VTY port is a logical terminal line used for Telnet or SSH access.
Users and User Interfaces
At a time, only one user can use a user interface. The configuration made in a user interface view
applies to any login user. For example, if user A uses the console port to log in, the configuration in the
console port user interface view applies to user A; if user A logs in through VTY 1, the configuration in
VTY 1 user interface view applies to user A.
A device can be equipped with multiple console ports, AUX ports, asynchronous serial interfaces, and
Ethernet interfaces, and thus multiple user interfaces of the same port type are supported. These user
