How NerveCenter Classifies a Node's SNMP Version

There are two main ways that NerveCenter classifies nodes:

For a detailed study of classification, refer to the white paper "OPEN NerveCenter: Node Classification," which ships with the NerveCenter online guides. Following is a summary of classification.

Each time NerveCenter attempts to classify a node, NerveCenter sends a series of classification requests (GetRequest messages) to the node. NerveCenter classifies the node based on the responses to these requests. Each request corresponds to an SNMP version -- either v1, v2c, or v3.

While classifying a node, NerveCenter attempts to detect the maximum supported version on the agent up to a maximum specified version, which you can configure in NerveCenter Administrator. So, for example, if you set a maximum classification version of v2c, NerveCenter never attempts to classify nodes any higher than v2c. (However, you can manually specify any version for a node and then test communication with the agent using that version.)

Based on the response to its messages, NerveCenter changes its SNMP version setting for the node.
