Usage scenarios of different SNMP versions
Version
Usage Scenario
SNMPv1
Applies to small-scale networks whose
networking is simple and security
requirements are low or whose security and
stability are good, such as campus networks
and small enterprise networks.
SNMPv2c
Applies 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.
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.
