Node Classification

NerveCenter 3.7 can communicate with devices that support any of the available versions of SNMP: v1, v2c, v3. All SNMP agents and network devices managed by NerveCenter, are represented as nodes in NerveCenter database. NerveCenter needs to know which version of SNMP to use when communicating with any of these agents. NerveCenter uses whatever SNMP version is assigned to the node object in NerveCenter database. Whenever a node is added to NerveCenter database, the node should have an SNMP version associated with it. Such SNMP version information can be assigned manually or automatically.

This white paper describes how NerveCenter identifies the SNMP version implemented on an agent and classifies the corresponding node object in the NerveCenter database. It also describes various ways NerveCenter uses to classify nodes. Finally, it describes how and when NerveCenter automatically classifies newly added nodes to its database.
