It’s really astounding all that we can do with network management today. We have progressed from simply being able to determine which devices were still functioning to being able to monitor traffic levels and even qualify and quantify the traffic. In this Geek Speak we’ll take a look at how to ensure you are doing the basics correctly so you can rest assured you are building on a solid foundation.

In this Geek Speak we’ll take a look at how to ensure you are doing the basics correctly so you can rest assured you are building on a solid foundation. Specifically, we will be examining:

• Understanding the abilities of ICMP and SNMP
• Interpreting ICMP and SNMP data
• Examining SNMP using SNMP specific tools
• Crunching the data - reporting

    • Back to the Basics - Network Management
      First of all, Why Should I Care About This?
      These technologies form the foundation of your entire IT Management abilities. With a solid understanding of the elements of your foundation, you can understand what to expect and what might be missing!
    • 20. Back to the Basics - Network Management
      The Roots of Network Management
      • ICMP
      “Are you there?”
      • SNMP
      “How are you doing?”
      • Syslog
      “News flash!”
    • 21. Back to the Basics - Network Management
      A Survivor! - ICMP Echo (Ping)
      • What kind of data can you expect?
      • 22. Ping is lightweight, low level, and powerful!
      • 23. Small packets = fast results.
      • 24. Handled by the NIC in most cases.
      • 25. Flexible options depending on implementation.
      • 26. Near-zero impact on network.
