💡What is Simple Network Management Protocol (SNMP)?
🌀 Simple Network Management Protocol (SNMP) is a way for different devices on a network to share information with one another. It allows devices to communicate even if the devices are different hardware and run different software.
🌀SNMP architecture SNMP has a simple architecture based on a client-server model.
🕯The servers, called managers, collect and process information about devices on the network.
🕯The clients, called agents, are any type of device or device component connected to the network.
They can include not just computers, but also network switches, phones, printers, and so on.
🌀SNMP data hierarchy: SNMP uses a tree-like format, under which data is always available for managers to collect. The data tree consists of multiple tables (or branches, if you want to stick with the tree metaphor), which are called Management Information Bases, or
🕯MIBs: group together particular types of devices or device components. Each MIB has a unique
identifying number, as well as an identifying string.
🕯Each MIB consists of one or more nodes, which represent individual devices or device components on the network. In turn, each node has a unique Object Identifier, or
🕯OID. The OID for a given node is determined by the identifier of the MIB on which it exists
combined with the node’s identifier within its MIB.
🌀SNMP Versions: SNMPV1- SNMPV2- SNMP 3
🌀 Application In Data Center: Using SNMP to connect between DCIM and NMS for Client.
