SNMP

Simple Network Management Protocol (SNMP) is a standard protocol used for managing and monitoring network devices. Here are the key aspects of SNMP:

• Functionality: SNMP allows network administrators to collect information about the status and performance of network devices such as routers, switches, servers, and printers. It also enables remote configuration and control of these devices.
• Architecture: SNMP operates on a client-server model. The servers, called managers, collect and process information from the clients, known as agents, which are the network devices.
• Management Information Base (MIB): SNMP uses a hierarchical database called MIB to organize and store information about the network devices. Each device has a unique identifier within the MIB.
• Versions: There are three main versions: SNMPv1, SNMPv2c, and SNMPv3. Each version offers different features and security enhancements, with SNMPv3 being the only version providing security.

SNMP is essential for effective network management, providing real-time updates and facilitating efficient network operations.

Transport protocol

SNMP uses UDP as its transport protocol because it doesn't need the overhead of TCP. Its well-known port is UDP port 161.
