Alert Messages

BD

The alert message generated by Simple Network Management Protocol (SNMP) agents is called a trap.

SNMP is a protocol used to manage and monitor network devices such as routers, switches, and servers. SNMP agents are software modules installed on these devices, which collect and store information about the device and its operations.

When a significant event occurs on the device, such as an error or a threshold being exceeded, the SNMP agent generates a trap message and sends it to the SNMP manager. The trap message contains information about the event, such as the type of event, the device that generated it, and the time it occurred.

The SNMP manager is the software application responsible for monitoring and managing the network devices. When it receives the trap message, it can take appropriate action, such as notifying an administrator or initiating corrective measures.

The other options provided in the question are also SNMP message types:

• GET: used by the SNMP manager to request information from the SNMP agent.
• SET: used by the SNMP manager to modify configuration parameters on the SNMP agent.
• INFORM: similar to a trap, but it requires confirmation from the SNMP manager upon receipt.

In summary, the SNMP agent generates a trap message when a significant event occurs, and the SNMP manager receives and acts upon the trap message.
