Configuring SNMP Settings for Nodes

A node must have SNMP version information before NerveCenter can poll the node or process a trap from the node. If the node is using SNMP v3, the SNMP agent must be configured properly on the node. See Using the SNMP Test Version Poll on page 58 for help testing communication with a node.

You can manually specify the correct SNMP version for the node or command NerveCenter to classify the node. If you specify the node as SNMP v3 or if the node is classified as SNMP v3, you can set the security level and, if applicable, the authentication protocol used by NerveCenter to poll the node. By default, NerveCenter sets the SNMP v3 security level to NoAuthNoPriv, which means that NerveCenter uses neither message authentication nor encryption when communicating with the agent.
