Login method
Default state
By default, you can log in to a device through modems. The default
user privilege level of modem login users is 3.
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 VLAN 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 directly, or through Telnet or SSH.
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 through Telnet or SSH
The two methods correspond to the following two user interfaces.
z
AUX 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 DTE.
z
VTY (virtual type terminal) user interface: Used to manage and monitor users that log in via VTY.
A VTY port 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 two AUX user interface, and five VTY user interfaces. These user
interfaces do not associate with specific users. When a user initiates a connection request, the system
automatically assigns an idle user interface with the smallest number to the user based on the login
method. During the login, the configuration in the user interface view takes effect. The user interface
varies depending on the login method and the login time.
