SIMPLE NETWORK MANAGEMENT PROTOCOL 
NAGENDRA NATH MISHRA
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.
ADVANTAGE USING SNMP 
• Standardized 
• Universally supported 
• Extendible 
• Portable 
• Allows distributed management access 
• Lightweight protocol.
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
THREE PARTS OF SNMP 
• SNMP Protocol 
• Structure of management system. 
• Management information base.
SNMP NODES 
• Managed nodes. 
• Management nodes. 
• Nodes which are not manageable by 
SNMP
SNMP AGENTS 
• Extendible agent 
• Monolithic agent 
• Proxy agent. 
• Gateway agent.
FOUR BASIC OPERATION 
• .Get 
• .GetNext 
• .Set 
• .Trap
SNMP AND OSIMODEL
LANGUAGES OF SNMP 
• Structure of management information. 
• Abstract syntax notation one. 
• Basic encoding rules.
SNMP DATA TYPE 
• Counter 
• Gauge 
• Time-Ticks 
• Opaque 
•INTEGER 
•OCTET STRING 
•OBJECT IDENTIFIER 
•NULL 
• IPAddress
