Introduction

This article discusses about the steps to configure SNMP on Dell N series switch.

Components of SNMP

SNMP Manager

SNMP Agent

Community String

SNMP Manager

• SNMP Manager is typically a computer that is used to run one or more network management systems(NMS).
• SNMP manager is responsible for communication between SNMP agent implemented Network Devices. (Switches, routers, servers etc.)

SNMP Agent

• SNMP agent is a program that is packaged within the Network Elements (switches, routers, servers etc.).
• Enabling the agent on the Network Element allows it to collect information from the device and makes it available to the SNMP manager when queried.

Community String

• The SNMP Community String is like a user id or password that is sent along with each SNMP Request which allows or denies access to a Network Elements (Switches, routers, servers etc.).
• If the community string is correct, the device responds with the requested information. If the community string is incorrect, the device simply ignores the request.
