Part II cuts through the hundreds of Cisco MIBs and thousands of MIB objects to highlight useful data for managing fault and performance in your network. Within Part II you will find selected MIB objects, show commands, syslog messages, and traps useful for fault and performance management of the included technologies. The information presented in Part II applies to the following Cisco devices: All IOS routers Catalyst switches, including 1900, 2900xl, 2900, 4000 series, 5000 series, 5500 series, and 6000 series Part II chapters are broken into three groups: Systems Managing router and LAN switch systems resources such as memory, buffers, and backplane. LAN Managing the LAN technologies implemented on routers and LAN switches such as ethernet, VLANs, and LANE WAN Managing the WAN technologies implemented on routers such as Frame Relay and dial up. Each of these sections are similarly formatted. First, the technology is introduced. While not exhaustive, the overview should provide you with enough information to understand the rest of the material in a chapter. Then, useful data is presented, split up into a performance section and a fault section. Each chapter presents the most useful MIB variables, SNMP traps, show commands, and syslog messages. Chapters 10 12 begin the discussion by providing information about network system hardware, processes, resources, and interfaces. Examples include CPU utilization, buffers, memory, and general interface management. Chapters 13 17 discuss the recommendations for LAN and WAN technologies. Topics include Ethernet (10BaseT, 100BaseT, and Gigabit), ATM, VLANs, Frame Relay, ISDN, and dial-up. |
