Introduction

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

Components of SNMP

  • SNMP Manager
  • SNMP Agent
  • Community String

SNMP Manager

  • The SNMP Manager is typically a computer that is used to run one or more network management systems (NMS).
  • The SNMP manager is responsible for communication with the SNMP agent on the 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.
