Login method | Default state |
| By default, you cannot log in to a device through a network |
| management system (NMS). To do so, log in to the device through the |
| console port, and complete the following configuration: |
• 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.). |
| • 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.
The system supports the following CLI configuration methods:
•Local configuration via the console port
•Local/Remote configuration through Telnet or SSH
The methods correspond to the following user interfaces.
•AUX user interface: Used to manage and monitor user that log in via the Console port. The type of the Console port is
•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
Only one user can use a user interface at a time. 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 AUX 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 one AUX user interface and 16 VTY user interfaces. These user interfaces are not associated with specific users. When a user initiates a connection request, the system automatically assigns the 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.
Numbering user interfaces
User interfaces can be numbered by using absolute numbering or relative numbering.
Absolute numbering
Absolute numbering identifies a user interface or a group of different types of user interfaces. The specified user interfaces are numbered from number 0 with a step of 1 and in the sequence of AUX, and
