What is Simple Network Management Protocol (SNMP)?
Simple Network Management Protocol (SNMP) is an application-layer protocol that transmits management data between network devices. SNMP belongs to the Transmission Control Protocol/Internet Protocol (TCP/IP) family.
What are the versions of SNMP?
The versions of SNMP include:
1. SNMP Version 1 (SNMPv1)
2. SNMP Version 2 (SNMPv2)
3. SNMP Version 3 (SNMPv3)
What are the components of SNMP?
The components of SNMP include:
1. SNMP manager
2. Managed devices
3. SNMP agent
4. Management information database (MIB)
5. SNMP object identifier (OID)
What Is SNMP Used For?
What is Simple Network Management Protocol? To maintain constant uptime and high-bandwidth network operations, network administrators control network devices and assign interfaces and ports. By strategically assigning the optimal ports that devices can use to communicate, IT teams make it easier for traffic to flow through the network more freely. Otherwise, there will be data “log jams” that result in latency and poor performance. SNMP device monitoring is a significant element of this process.
SNMP enables administrators to monitor how devices are performing and make changes to network devices so that data moves through the network more efficiently. But first, to use SNMP monitoring, the SNMP agent implemented on a network device has to be configured to send monitoring data to an SNMP manager (more on this below). Once done, admins can concentrate on making adjustments to optimize network performance.
Admins can also track the availability and performance of SNMP network devices using the insights SNMP provides, enabling them to better maintain the health of the network. By using the appropriate SNMP monitoring tool, admins can keep track of various SNMP protocol versions and gain a comprehensive view of the entire network. Also, SNMP monitoring tools make data available in simple formats like graphs and dashboards.
How Does SNMP Work?
Your network experiences different kinds of traffic throughout the day as users browse the web, transfer files, download files, and engage in other activities that involve sending and receiving data. SNMP communicates with your network to get details about each network device’s activities. For instance, it monitors the number of packets, bytes, and errors sent by your websites, as well as the number of hits it receives per day.
SNMP also communicates with devices on your network by sending queries or messages—known as protocol data units (PDUs)—to each device. Network administrators can track almost any data value they specify using these messages. This enables them to pull data from each device to see how it is performing.
