Part II : Managing Devices and Technologies

Part II: Managing Devices and Technologies

Part II is for all audiences and provides concise, detailed information on managing routers and switches. It includes coverage of device and system management, LAN management, and WAN management.

Each chapter provides information on how each of the technologies works, detailed explanations on what the authors consider the most important aspects to manage, and helpful reference to other data that may be useful to network management.

The authors feel that the objectives can be accomplished through conversational instruction using the following method:

1. Provide brief explanations of each of the manageable technologies. How can you determine what to monitor and set thresholds against if you do not understand the technologies you are trying to manage?

2. Recommend the top data variables to manage for a technology, providing all of the information that a network engineer will find useful when setting up fault and performance management. No ad-nausea reprints here; we provide you with the top items to watch for and point you to the MIBs posted on the web for more information.

Although some background and context is provided about devices and technologies, it is not the goal of these chapters to provide exhaustive architectural details. Rather, each chapter provides enough example/context information to support the discussion of SNMP MIB objects, SNMP traps, show commands, and syslog messages.

Throughout Part II there are many output Examples from show commands. The relevant lines of output have been annotated and cross-referenced to explanations that follow the Example. This includes the association of relevant SNMP MIB objects to show command output.
