SNMP

SNMP (Simple Network Management Protocol) is an application layer protocol that uses UDP for transport, for monitoring and managing network devices.
System administrators can query devices to gain information on the devices on the network.

It works on ports 161 and 162 and there are 3 components:

  • SNMP Manager: querying and interacting with SNMP Agents on devices
  • SNMP Agent: software running on the devices that responds to the SNMP Manager
  • Management Information Base (MIB): a database that defines the structure of data available to SNMP
