Configuring an Initial User for Discovering an SNMP v3 Agent

To discover an SNMP v3 node, NerveCenter sends a GetRequest message to that node with the following parameters:

• SecurityLevel: set to (noAuthNoPriv)
• MsgUserName: set to zerolength (` `)
• MsgAuthoritativeEngineID: set to zerolength (` `)
• Empty variable bindings (variable-bindings=` `)

  Note    For exact procedural details about configuring SNMP v3 agents, consult the user documentation supplied by your SNMP v3 agent provider.

A properly configured SNMP v3 agent responds to the GetRequest with a Report PDU, which includes its local snmpEngineID (supplied within the msgAuthoritativeEngineID field). After NerveCenter obtains the snmpEngineID, NerveCenter can discovers the node as an SNMP v3 agent.

This process of discovering SNMP v3 agents is recommended in SNMP v3 specifications. Most of the SNMP v3 agents are preconfigured with an "initial" user and respond in the manner previously described to the GetRequest, so you generally won't have to perform any special type of configuration on your agent. Refer to the user documentation supplied by your SNMP v3 agent provider for detailed information.
