Version
Usage Scenario
SNMPv2c
This version is applicable to medium and
large-scale networks whose security
requirements are not strict or whose security
is good (for example, VPNs) but whose
services are so busy that traffic congestion
may occur.
Using informs can ensure that the messages
sent from managed devices are received by
the NM station.
SNMPv3
This version is applicable to networks of
various scales, especially the networks that
have strict requirements on security and can
be managed only by authorized
administrators, such as the scenario where
data between the NM station and managed
devices needs to be transmitted over a public
network.
If you plan to build a new network, choose an SNMP version based on your usage scenario. If
you plan to expand or upgrade an existing network, choose an SNMP version to match the SNMP
version running on the NM station to ensure the normal communication between managed
devices and the NM station.
1.2 Configuring a Device to Communicate with an NM
Station by Running SNMPv1
After SNMPv1 is configured, a managed device and an NM station can run SNMPv1 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
Sends requests to the managed device to perform the GetRequest, GetNextRequest,
GetResponse, GetBulk, or SetRequest operation, obtaining data and setting values.
l
Receives alarms from the managed device and locates and rectify device faults based on
the alarm information.
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.
1.2.1 Establishing the Configuration Task
Before configuring a device to communicate with an NM station by running SNMPv1,
familiarize yourself with the applicable environment, complete the pre-configuration tasks, and
