1.4 Configuring a Device to Communicate with an NM
Station by Running SNMPv3
After SNMPv3 is configured, a managed device and an NM station can run SNMPv3 to
communicate with each other. To ensure normal communication, you need to configure both
sides. This section describes only the configurations on a managed device (the agent side). For
details about configurations on an NM station, see the pertaining NM station operation guide.
The NM station manages a device in the following manners:
l
l
In the following configuration, after basic SNMP functions are configured, the NM station can
manage the device in these manners. For details on how to configure finer management such as
accurate access control or alarm module specification, see the following configuration
procedures.
1.4.1 Establishing the Configuration Task
Before configuring a device to communicate with an NM station by running SNMPv3,
familiarize yourself with the applicable environment, complete the pre-configuration tasks, and
obtain the data required for the configuration. This will help you complete the configuration task
quickly and accurately.
Applicable Environment
SNMP needs to be deployed in a network to allow the NM station to manage network devices.
Assume your network has a strict requirement on security, only authorized administrators can
manage network devices, and the security and accuracy of transmitted network data need to be
ensured. For example, the data between the NM station and managed devices is transmitted over
a public network. In this case, SNMPv3 can be deployed. The authentication and encryption
functions provided by SNMPv3 ensure the security of data sending and normal communication
between the NM station and managed devices.
Pre-configuration Tasks
Before configuring a device to communicate with an NM station by running SNMPv3, complete
the following task:

Sends requests to the managed device to perform the GetRequest, GetNextRequest,
GetResponse, GetBulk, or SetRequest operation, obtaining data and setting values.
Receives alarms from the managed device and locates and rectify device faults based on
the alarm information.
