Exploring SNMP: The Backbone of Network Monitoring

Exploring SNMP: The Backbone of Network Monitoring

What is SNMP? SNMP stands for Simple Network Management Protocol, a network protocol that facilitates the exchange of management data between network devices.

History: Developed in 1988, SNMP was created to standardise network management across different devices and has since become one of the most widely adopted protocols for network monitoring.

Security: SNMP enhances security by using encryption and authentication techniques, ensuring secure communication between network devices and users.

Purpose: SNMP is primarily used to monitor and manage network devices, such as routers, servers, and printers. It provides network engineers with a standardised method to gather critical data, ensuring smooth network operation.

How it works: SNMP belongs to the TCP/IP family and uses a client-server architecture. It enables network devices to share information with a Network Management System (NMS) using polling and traps to gather periodic statistics.

Protocols & Ports:
SNMP Polling: UDP 161
SNMP Traps: UDP 162
