Guide on Simple Network Management Protocol (SNMP)
What is Simple Network Management Protocol (SNMP)?
SNMP is an application-layer protocol designed to manage network devices. It is used for collecting information from, and configuring, network devices, such as servers, printers, hubs, switches, and routers on an Internet Protocol (IP) network.
Why is SNMP important?
SNMP provides a standardized framework and common language used for monitoring and managing the devices in a network. It is important because it helps network administrators manage network performance, find and solve network issues, and plan for network growth.
How does SNMP work?
SNMP works by sending protocol data units (PDUs) to different parts of a network. SNMP-compliant devices, known as agents, store data about themselves in Management Information Bases (MIBs) and return this data to the SNMP requesters.
Exam Tips: Answering Questions on Simple Network Management Protocol (SNMP)
1. Be able to define what SNMP is and its function in network management.
2. Understand the basic components of SNMP including the SNMP manager, SNMP agent, MIB, and PDUs.
3. Know the different versions of SNMP (v1, v2c, and v3) and the improvements each brought.
4. Be familiar with the concept of SNMP 'traps' and 'polling'.
5. Ability to explain the security features (or lack thereof) in different SNMP versions.
Remember, exam questions are not only about memorizing definitions but demonstrating a clear understanding of how SNMP fits into overall network management.
