Table 1-2  Application Scenarios of Different Versions
Version Application Scenario
SNMPv1
SNMPv1 is applicable to small-scale networks with simple networking, good stability and 
low security requirements, such as campus networks and small enterprise networks.
SNMPv2c
SNMPv2c is applicable to medium and large-scale networks with low security requirements 
(or are already secure enough like VPN networks) and heavy traffic. The added feature 
Inform helps to ensure that the notifications from the switch are received by the NMS host 
even when network congestion occurs.
SNMPv3
SNMPv3 is applicable to networks of various scales, particularly those that have high 
security requirements and require devices to be managed by authenticated administrators 
(such as when data needs to be transferred on public networks).
