SNMP Network Management: The Essentials

THE WORKSHOP

Network Management is about monitoring and managing multi-protocol networks using the SNMP Protocol. The workshop reviews the SNMP Protocol structure, Network management applications, and query agents. There will be a detailed discussion on identifying objects, MIBs and SNMP devices.

WORKSHOP OBJECTIVES:

  • You will understand the structure and operation of SNMP
  • You will use SNMP to identify faulty devices
  • You will use RMON to analyse remote network information
  • You will interpret and explain MIB I and MIB II (Public/Private/Proprietary)
  • You will track the important variables on your network
  • You will install and configure a typical Network Management Package
