SNMP allows for remote and local management of networked devices. It is comprised of agents, which collect information from managed nodes, and managers, which request information from agents. SNMP uses a client-pull model, where the manager pulls data from the agent, and a server-push model, where the agent pushes trap messages to the manager. It has four basic operations: get, getnext, set, and trap.

2. SIMPLE NETWORK MANAGEMENT PROTOCOL
 SNMP is a tool (protocol) that allows for remote and local
management of items on the network including servers,
workstations, routers, switches and other managed devices.
 Comprised of agents and managers
 Agent - process running on each managed node collecting
information about the device it is running on.
 Manager - process running on a management workstation that
requests information about devices on the network.

3. ADVANTAGE USING SNMP
• Standardized
• Universally supported
• Extendible
• Portable
• Allows distributed management access
• Lightweight protocol.

4. CLIENT PULL AND SERVER PUSH
• SNMP is a “client pull” model.
The management system (client) “pulls” data
from the agent (server).
• SNMP is a “server push” model
The agent (server) “pushes” out a trap message
to a (client) management system

5. THREE PARTS OF SNMP
• SNMP Protocol
• Structure of management system.
• Management information base.

6. SNMP NODES
• Managed nodes.
• Management nodes.
• Nodes which are not manageable by
SNMP

7. SNMP AGENTS

• Monolithic agent
• Proxy agent.
• Gateway agent.

8. FOUR BASIC OPERATION
