Logging in through SNMP
By default, SNMP login is disabled. To use SNMP service, complete
the following configuration tasks:
• Assign an IP address to a Layer 3 interface, and make sure the
interface and the NMS can reach each other. By default, the LB
module has the IP address 192.168.0.1/24 configured for the
interface GigabitEthernet 0/1.
• Configure SNMP basic parameters.
Logging in to the LB module from the
network device
When the LB module is inserted in a switch or router, you can use
OAA to log in to the LB module from the CLI of the switch or router.
CLI user interfaces
The LB module uses user interfaces (also called "lines") to control CLI logins and monitor CLI sessions.
You can configure access control settings, including authentication, user privilege, and login redirect on
user interfaces. After users are logged in, their actions must be compliant with the settings on the user
interfaces assigned to them.
Users are assigned different user interfaces, depending on their login methods, as shown in Table 2.

User interface assignment
The LB module automatically assigns user interfaces to CLI login users, depending on their login methods.
Each user interface can be assigned to only one user at a time. If no user interface is available, a CLI
login attempt will be rejected.
For a CLI login, the LB module always picks the lowest numbered user interface from the idle user
interfaces available for the type of login. For example, four VTY user interfaces (0 to 3) are configured,
of which VTY 0 and VTY 3 are idle. When a user Telnets to the LB module, the LB module assigns VTY
0 to the user and uses the settings on VTY 0 to authenticate and manage the user.
User interface identification
A user interface can be identified by an absolute number, or the interface type and a relative number.
An absolute number uniquely identifies a user interface among all user interfaces. The user interfaces are
numbered starting from 0 and incrementing by 1 and in the sequence of console, AUX, and VTY user
interfaces. You can use the display user-interface command without any parameters to view supported
user interfaces and their absolute numbers.
