SNMP Notes
- Trap: A trap is an alert message—for example, a trap might alert the SNMP manager to the failure of a device. SNMP trap monitoring is crucial, as it notifies you of issues so you can address them proactively.
- Get: This is a basic information request. A Get message is the main way the SNMP manager gets information from an agent.
- GetNext: As the name implies, a GetNext message sends for the next segment of information.
- GetBulk: This lets the SNMP manager request an array of information via a sequence of GetNext requests, meaning a bigger segment of the MIB can be queried.
- Set: Set messages allow the SNMP manager to give agent instructions regarding changes to settings on a monitored device.
- Response: The response is simply the reply from the agent, acknowledging the request. Inform: This is the SNMP manager’s version of the response message, acknowledging receipt of a trap.
Ports: 162 for trap, 161 others.
