Can you tell me how does SNMP (Simple Network Management Protocol) work?
The simple network management protocol (SNMP) use for monitoring of network-attached devices for any conditions that warrant administrative attention. For example all of the following devices can use SNMP for managing devices on IP networks:
- Network router
- Network switch
- NAS server
- ADSL ISP router / modem
- Linux / UNIX / Windows servers
- Workstation and more.
Administrator can find or manage network performance, solve problem or even optimize it further. SNMP works at the Application Layer of the Internet Protocol Suite (Layer 7 of the OSI model).
You can find out many resources on the Internet that explain SNMP. Take a look at following articles:
