After SNMPv1 is configured, a managed device and an NMS can run SNMPv1 to communicate with each other. To ensure communication, you need to configure the agent and NMS. This section only describes the configuration on a managed device (the agent side). For details about configurations on an NMS, see the NMS operation guide.
To allow the NMS to manage network devices, configure SNMP.
If the network is secure and has few devices (for example, a campus network or a small enterprise network), SNMPv1 can be deployed to ensure communication between the NMS and managed devices.
SNMPv1 has a security risk. Using SNMPv3 is recommended.
Before configuring a device to communicate with an NMS using SNMPv1, configure a routing protocol to ensure that the router and NMS are reachable.
